  1. So, I'm going to order coils as 3 and 5 are apparently misfiring. The question here is: Are the left and right side coils the same, or is there a left and right side coil setup? Yes, to some this might be a dumb question, and it might be, but I don't want to order one part to learn I acquired the wrong side. Thanks!
  2. Thanks! I'll start with the coils and plugs -- I wanted to do a good tune up anyway. I don't have a code reader (it's on my Christmas wish list) so I can't check to see what the alarm is...
  3. Hello all! I've got a 1999 996 Carrera that hasn't had any mechanical issues outside of a water pump replacement earlier this year. Just today I noticed that when in 3rd to 5th gear (I haven't had it on freeways to see if it's in 6th too, but most likely it does) in the mid rpm ranges (2500 - 3000+) there is a vibration that I can feel through the gas pedal and throughout the car. When the gas is let up and/or when the vehicle is coasting the vibration goes away. The vibration seems to only occur on acceleration and does seem to be coming from the rear. The check engine light came on as well, at first it was flashing and is now constant. Any tips on what this could be? Drive shaft? Engine mount? Catalytic converter? .....?
  4. Got it all done. Yes, without the vacuum filling pump it was time consuming. The key there was to run the heater when filling it. Every morning I check the level and top it up. No worries now as the temp only goes above the 180 mark at extended stops, but it only goes up to around 190. One small question: When I put it all back together the check engine light came on. I figured it was from disconnecting the sensor on the air intake, so I disconnected the battery's positive cable and it did the trick. However, this morning after a small jaunt the light came on again. Suggestions?
  5. Update.... All parts are in. Yes -- it was the water pump. Not a difficult surgery with the exception of the most inboard 10mm bolt (between the water pump and drive pulleys). That was not a lot of fun to remove/replace. Anyway, first batch of coolant is in. To check the rules for filling the coolant I believe I follow this procedure: 1) Flip the pressure release valve and remove res cap. 2) Fill coolant 50/50 mixture to neck of reservoir. 3) Run engine. 4) Fill again and replace cap. 5) Let engine run and warm up until cooling fan kicks on. 6) Remove cap and fill again. 7) Lather, rinse, repeat... British cars are so much less complex. *laughs* Then again, balancing those Zenith-Strombergs every other day did kinda suck. At least this is a once-every-ten-year (or so) thing.
  6. Part is ordered... Not as expensive as I initially thought *wipes brow*. Paul -- I read your post -- GREAT job! And yes, I'll be needing that new fangled vacuum pump to load the juice when I fill it up. I'll also be replacing as many plastic fittings with brass as I encounter them. Thanks for the suggestion!
  7. I'm interested in this "fix" too. I live in Florida, so the heater is kind of a vestigial organ here.
  8. Update... I let her sit all weekend. This morning I figured I was going to drain the coolant anyway, so using the 'ol shadetree pitcher and gardenhose fill technique, I filled (and filled, and filled) the reservoir until I noticed the puddle forming under the car. Looking under the car it appears that ALL of the fluid is running out the water pump. So guess what I've got to do... Next stop -- price a water pump for a 1999 Porsche Carrera. Woot!! Nice thing is that the water pump doesn't appear to be a difficult fix on these (other than lowering the engine a bit), unlike V-8s with the water pump inside the engine. Wish me luck... Ugh.
  9. Lots to look into... Small update...... I'll keep y'all posted on the progress as it unfolds. The fluid definitely is coming from the left rear side of the engine, which does point me toward coolant reservoir tank, cap, or combination thereof. The fluid is pretty clear, which might mean there was a greater concentration of water to coolant, possibly done where I bought it as they might have thought a car's a car. As the car rolls the temp goes down (it did start to creep up this evening, unlike earlier today) but definitely rises a bit at red lights (still well inside of "safe" temps), so I don't think it would be the water pump *fingers crossed*. There is also a belt chirp coming from the right side on acceleration, then a small burst of energy when the chirp stops -- could that be related to the cooling system or A/C? Either way the belt needs to be tended to as well. I intend to have the dealer do all the diagnosis (and pay for it) and go from there. If they used the wrong coolant and the old coolant turned to gel (as I've read about, but not sure of the truth behind it) I'd much prefer the financial burden be on someone else's shoulders for that mistake. I'm used to playing with my cars, but I prefer to have everything at 100% BEFORE tinkering so I have a better idea where to start when something goes south. I hope I didn't buy someone else's nightmare. *laughs*
  10. Hi Guys and Gals... I've got a '99 Carrera that I recently purchased. This afternoon I noticed a coolant smell and at slow parking lot speeds I saw steam coming from the rear. The temp gauge isn't registering hot but the light at the upper right of the gauge is blinking. Pulling in to my drive I saw a trail of liquid (obviously coolant) behind the car. So, with this information I did some research via the owner's manual that says "permanent" coolant. I've never heard of such a thing. It also says to pre-mix the coolant based on ambient temperatures, which makes me think it's just like any other coolant. More research online. Porsche recommends Porsche coolant (go figure) the same way Harley Davidson recommends HD oil. More research. I read that Porsche uses an "organic" coolant that if mixed with other coolants will turn into a gel and, well, BOOM -- a very expensive boom at that. I'm looking for educated guesses here. I don't know what coolants (if any) the previous owners used. If they used Porsche coolant, is there a brand that is similar or exceeds this spec? Is there a way to tell what kind of coolant the previous owners used? I mean, it smells like coolant, but I can't see the colors that were described in other articles -- pink-ish, green, or yellow. Should I just drain the entire cooling system and start from scratch? What do the pros here recommend...???
  11. I was wondering if the "disconnect the positive cable, turn the key over for a few seconds, then reconnect the positive cable" thing would work. It seems to be the fix for the 5999999 odometer reading, maybe it'll work with my inconvenience.....
  12. Yes, the display worked prior to the battery install. It's one of those things where I don't really use it, so I didn't notice it right away. I guess it was one of those "Huh." moments....
  13. Hey all! New here to the forum. Anyway, here's the issue ---- 1999 Carrera Cabrio, 85K miles, 6sp. The odometer/tripometer isn't showing up on screen. I don't have the onboard computer for mileage, etc., just the basic instrument cluster. Speedo and all other dash functions work, only that one screen isn't supplying info. Last week I did have battery work done -- could this be a part of the problem? Any advice would be welcomed. Thanks!!
