    JFP, Jon and Loren...  many thanks for the support and direction.  I removed the battery and panel all looked good, I also removed the top hat cover next to the bulkhead on the trunk side, again no tell tale signs of cracks there either.

     

    I guess next will be to look at the charcoal canister and gas fill check valve.  I think I'll change out the charcoal canister first. 6 years ago when I installed the LS3 V8 I had a problem connecting up the charcoal canister to the new conversion.  A friend of mine from the airport holds certificates on welding, A/C, Electrical, Diesel engines on unlimited tonnage for ships.  He's a civilian contractor hired by the navy to be in charge of maintenance on big ships...  Where he goes is always a secret.  This guy will always be the smartest person in the room... Anyway the Porsche might still be sitting in the garage if he hadn't figured out how the system worked.  Took him 30 minutes to draw out the system and 10 minutes to change some hoses.  But the charcoal canister had been full of gas, but the system has never given me a lick of trouble since, so long story short, that is why I might start with the canister...

     

    Loren, say again how you assign points...  Thanks

  2. I put the car on the lift and removed the belly pans...  I was hoping that would find the source of my stinky gas smell once the belly pans were removed.

    Nope, no stains on the belly pans and no wet hoses.  So I guess the next step is to check/replace the fill pipe check valve and or the charcoal canister.  Can anyone tell me if the check valve is stuck open will the car run fine and could be the source of my gas fumes...

     

    If there's a problem with the check valve will it show up on my Durametric program?

     

    Thanks,

  3. Do you have a TPS... Throttle position sensor or because your throttle body is cable driven you do not...    Can you manually pull the throttle back to an idle either at the pedal or throttle body...

     

    I have a similar problem, but properly not related.  I replaced the TPS and throttle body, now it takes several ,minutes for the engine to return to idle...

  4. Jon,  That's a good idea to step back before throwing a lot parts at the car.  I have my T-Bird restomod project on the lift right now.  To do it right I need to drop down the belly pans for a good once over.  

    Speaking of belly pans...

    Here's a tip if you're tired of replacing the belly pan brackets/retainer clamps.  I used aircraft loose nut plates and riveted them to the braces.

  5. The fumes went away, now there back with a vengeance...  I changed the gas cap which was cheap and worth a try, what are the possible choices?

     

    1.  Per 356, check for hairline cracks in the gas tank sending unit...

     

    2. Per Judgejon, replace the check valve behind the right side fender liner.

     

    3. Could the charcoal canister be full.  Where is the charcoal canister?

     

    4. Can this problem be identified with my Durametric program...

     

    Thanks, all replies will be appreciated...

  6. Jon,

     

    The Bride of Frankenstein would blow the doors off your ''409'...  With a taller ring and pinion she clocks out

    on paper at 206 MPH at redline in 6th gear, but not with me in it...

     

    On an earlier post I mentioned that the idler pulley bolt backing out which is not good...  If you ever have to replace that bolt

    I would recommend using loctite.

  7. 17 hours ago, DBJoe996 said:

    A check engine light on simply means one of the parameters the ECU monitors was off, and it always records a code that tells you specifically what was wrong.  There are literally thousands of various codes that will throw the CEL.  Next time, read the code before you clear codes.  That code or codes will point you in the right direction.

     

    Also, I would  get in touch with whomever did the LS3 conversion and ask them how they rigged the "fly-by-wire" throttle conversion.  There is going to be a lot of frankenstein parts involved with an LS3 conversion.  Just the fact the GM OBDII port didn't work but the Porsche OBDII port did is really questionable.  Did they somehow "marry" (connect) the Porsche ECU to a GM ECU?  How?

    Joe,

     

    I know I'm in dangerous territory pushing this conversion, but it's been a fun to drive car, gooobs of power and reliable.  My point Joe is the electrical was the most challenging part of the conversion snd was a major expense to get it done right. It does bring together different parts, but the word Frankenstein might be a little over the top...  Today the after market people have develop easier programs that tend to be plug and play where as 8 years ago you better have your Phd in order...

  8. No, I believe both ECU's have their own job...  The Conversion utilized the GM gas pedal, so like you I was surprised when the Porsche OBD port cancelled the check light.  It has been years since I hooked up the Durametric program, but I did today with these results...

     

    I just thought I need to see if I can date when these codes were thrown...  At the top of the attachment it says, "Current /Fault Codes.  I want to get to the bottom of

    this pretty quick, I've never have been flat bedded home so far.  I did get stuck in Winslow, AZ for one night with the original engine.  The idler pulley bolt backed out, 

    a local towing service came out with his flatbed, took me to the Chrysler dealer, charged me $85..   They had the Porsche dealer in a neighboring town overnight

    the parts.  I was on the road again by 10:00 the next morning...  All in all it was a memorable experience and meant some nice people.

  9. Coming home in the middle of the day, probably high 90's, good oil temp and water temp

    was good when all of a sudden my gas pedal went away and the LS3 V8 cough and quit.

    I tried to restart without success, Finally it started and got me home without further incident.

     

    I plugged y OBD II reader in to the GM port and it wouldn't clear, then plugged it into the

    Porsche port and it cleared.  I have 90,000 miles on the 2003 C4S model and 25,000 on the LS3 motor.

     

    NMy question is this a routine mileage event or something else?  Certainly it was more of

    a "have your car service" event since the gas pedal went away and the engine stopped.  I was surprised that I

    cancel/erase it on the Porsche OBD port.

     

    I was hoping for some rare insight which has its complications, but still puts a smile on my face...

     

    Thanks,

  10. Mike,

     

    Obviously it's something,  I installed a short shift kit in my '03' and don't remember any wiring attach to the the shifter?  But then again I can't remember what I had for breakfast.  On a rare coincidence have you checked the lamps in the tail light housings....  I doubt that the back up lights are on their own fuse, but have you checked that?

     

    Keep us posted even if it means embarrassing yourself...

     

    Mitch

  11. BM,

     

    When you say the A/C kicks in what does mean...  The first thing I would check is to be sure the clutch on your compessor is engaging,  Stick your head under the back bumper close to the A/C compressor then have someone turn the A/C on...  You should hear the pulley coming together with the clutch plate.  Also, if it's working you can no longer turn the clutch plate..

     

    And you're sure that you have the correct amount of Fregon, I believe our system takes 1.9 lbs. of R134 Freon... Also, it's good to include the year and model of your car.  There's a lot of posting on the blowing insulation.  I have it and it doesn't seem to have  made any difference.

     

    I share your frustration as I have a delayed start with my A/C after a cold start of about 5-10 minutes, once the car is warm up the A/C fires right off...  I'm sure you'll get some good

    input from the other members...

     

    Good luck and Welcome

  12. I love the looks and hips on the wide body...  I had a '84' Turbo Look, with original paint to sample, but got tired of the whales tail.  I think the 996 

    is a great design and will hold it's looks for a long time.  After all the test of good design is how will it age and look 10-20 years out.  I think the 996 will do well,

    it checks all the boxes for me.

     

    I see you're from CA, where is Mendonesia California...  LOL

  13. Might be an easy place to start, although I replaced it about 4 years ago.  I'll give a close inspection and go from there.

    I replaced the bumper cover with a modified 997 GT2 bumper cover.  It was an aftermarket fiberglass piece.  It was so far off from fitting, not even close.

    I already had the wrong one sold to me sold to me by another dealer so I was a concern buyer, the guy swore it would fit.  I probably have over 40 hours in fiberglass work to get it this close.

    The big advantage is for the 3rd water radiator to have good flow through air...

     

    Plus, I like the LED DTR lights....   Also, I have 3 front directional lights, 1 in the headlight unit, the LED DTR light has an amber turn signal light and we wired

    up the fender side marker light to also be a directional light.

     

    Thanks all for your help...

  14. What has your Porsche Service Center said in regards to the rust...  No question the rust is extreme, are you sure the shocks are original equipment?  I think you'll have to suck it up and have the shocks replaced at your expense.  There's always associated cost with owning any car, let alone a Porsche. 

     

    Wayne Dempsey's book "101 projects for your Porsche" says you could spend up to $3,000 and 20 hours to replace the shocks, bushing, tie rods, , sway bar and associated hardware.  If you're a DIY hands on it might be a good project.  Dempsey's book would would walk you through the task.
