take a look at tire balance as well... Mine had a bit of a shake and I thought it was the rotors. When I had different wheels put on the shaking went away. When it was at the shop I looked at the pads and it looked like there was plenty of life left in them.

Anyone can give me any info on where to find the DME Test Plan for a 1984 911? Can it be bought or downloaded from anywhere?

check your 02 sensor.

What weight of oil should I use in my 84 911? is synthetic needed? I live in socal so its usually warm even though our winter just kicked in.

I searched but couldn't find a clear answer. Any help would be appreciated. Thanks.

There is instruction on this site in the DIY section. You have to be a contributor to see it. It is money well spend..... 996TT oil change instruction

You have to drain the oil from 4 position. The bottom of the oil tank, the engine case and the two turbos. The oil in California, I guess Mobil 0W40 is the one used by many peoples....

+1 The DIY is very good here.

Correct, 4 places. Be careful when you do the oil tank, it will dump oil all over the place. I run 0W40 in SoCal and it runs fine... some track days on it as well and no issues.

Can you use a Durametric to see if you have a ECU flash? I have a 996 Turbo and the previous owner said it was tuned. I want to verify if it was or not, would the Durametric do it and if so, how?

Durametric Pro and 993 plug in Orange Ca 92867.

What does the drive link function do? I'll try when i get home but want to know what it does first.

unplug the battery when the engine is running. if the engine dies, the alternator is bad. if the car still runs, the alternator is fine.

Could I please get a code as well

01 996tt

cdr-220

type 4462

serial y5037123

thanks

You can use any jack, as long as the jack pad fits securely on one of the jacking points and does not "slip off" sideways (or front to back) the jacking point as you lift that side of the car. Take a look at the shape of the jacking points and you will see that it has a hole in the middle. Some vendors sell jack pads that specifically fit that profile.

After you have safely lifted the car by one of its jacking points with your jack, you should place a jack stand under an appropriate part as a safety, back up feature in case your jack fails. If you are replacing your wheels with winter wheels, it is a good safety practice to place one of the wheels (that is not at that moment mounted on the car) under the car in an area near where you are removing a wheel.

Where is a good place to put a jack stand? I wasn't able to find one while working on my car a few weeks back.

P0300 is the general misfire code that's always set whenever there's misfires and P030x is the cylinder specific misfire. If he has access to a Durametric, there should be some "fault type" info for P0300 that could help isolate the problem. There's a whole bunch of stuff to check including electrical related (plugs, coil packs, wiring) and mechanical (secondary air system, valves, exhaust system, fuel injector/supply). Also, if there is any "freeze frame" info from the Durametric tool, there could be some info to help troubleshoot in the way of what the fuel adaptation (fuel trim) was doing when the misfires triggered the CEL. Also, a flaky crankshaft position sensor can be a source even if it didn't trigger a code.

I do have the Durametric. How do I use it to help me more. I just got it and haven't played around too much with it.

Methyl hyrate is methyl alcohol. You can get it at hardware stores,paint stores. Its used in the fuel tank and it absorbes water. Its a fuel antifreeze. In a full tank i would dump about a litre in. I have used it since i was a kid to run my toy steam engine. Its a great fuel.

It sure sounds like a fuel problem to me . I would bite the bullet and take your car into a porsche shop. Just get em to find out WTF is going on. Or.. You could buy a fuel pressure tester which is a tester to test your fuel pressure. :)

Since the car is starting up fine but then sputters to a halt its IMO running out of gas. Could be fuel filter,fuel pump. Since all cars now have in tank fuel pumps its expensive replacing them because in most cases you have to drop the tank. Labour costs can get high + fuel pumps in most vehicles are friggin outragously expensive.

Curious. What were the conditions before your problem started. Was it cold? Raining? Just filled up the tank with unknown fuel? Ran you car close to empty? Did it just start doing this out of the blue?

I bought the car used. It sat for a few years without it being driven. When I got it, I replaced the air filter and filled up the fuel tank (It was towed to my house from cross country and there was no fuel it in when it arrived). I drove it around town for a little and it kind of ran rough when I got near home and the check engine light turned on. When I checked the light it was a misfire on cylinder 5... then I changed the spark plugs and moved all the coils around. This is where I am at... a few weeks ago it was freezing here at night.

I might go try to find some Methyl and put it in there to see if that might help... is that all I ask for at a hardware store? If that doesn't work, I'll check all the fuel lines and see if I can figure out why it wouldn't be getting fuel... do you think its just cylinder 5 not getting it or all of the engine?

I went by the dealer and the car doesn't have a serviceable fuel filter. It is built into the fuel pump and I'd have to drop the fuel tank to get to it.

Any other ideas to look at?

Yup. Its being fuel starved. Check fuel filter/replace it or anything related to fuel. I would also dump some methyl hydrate into your fuel tank in case you have water in your fuel. Cold weather water turns to ice and blocks fuel lines etc.

What is methyl hydrate? Where do I buy it from and how much do i put in it? Thanks for everything... I will look into the fuel filter.

It sounds to me not compression issues or valve issues with so few k on the car.

Question.. When the motor fires up, does it fire up and seem to run normal then sputter and die? Or, does it run like crap from the get go?

Good luck.

It starts and runs fine for 15-30 seconds and then starts to die. If I rev it it will stay running, but if I stop it will slowly die. any ideas?

Have you checked compression on that cylinder to make sure there is no issues with the valves or cylinder itself?

If low compression -- than check leakdown for source.

If no issue there -- do you get oil or fluid build up in that cylinder?

Lastly -- maybe there is a fuel lnjector probelm.

Thanks... how do you check compression... will a Durametric tool tell me or is there more work to it?

I used those before for a VW and they were good. I'd say it was better then the OEM stuff. I was looking for some rotors for my Boxster and was going to buy those but they didn't have the right side in stock. I ended up buying some from pelican parts, they were cheaper and its OEM. I'm new to Porsche, but from all my research they are suppose to have really good brakes.

Its on an 05 Boxster 2.7L manual. 26,300 miles.

I got codes P0300 and P0305.

I changed the coils on cylinder 5 and 6 and still got the same codes.

I changed all the spark plugs and changed the coils around on each side and still got the same codes.

All the coils looked good, no cracks.

I checked to make sure they were plugged in all the way and they were.

When I start it, it runs a little and dies. It will start again, and if I rev it it will drive (I had to move it from my driveway), but dies.

I figured it can't be the spark plugs, since they are new. It can't be the coils since they are not in their original spot.

Any help? Anything else I can look for?

O2 sensor, pre cat if I remember right. It all three cylinders come on at once it is usually an O2 sensor.

How do I access the engine on my 05 Boxster? I don't have an owners manual to look it up.

I'm down in Orange (orange county) and work in Irvine. My dash board looks like a christmas tree. I replaced the battery so I know that a few of the lights is from that. I can pick it up and drop it off from your location or I can meet up with you during my lunch. I don't really want to drive the car though until i reset the lights. Let me know, thanks.
