yes it is my first one.... We have been together for about 9 years so we think it is a good time.

As far as the mis goes. I changed the spark plugs, and it does not seem to run any better. can I put 98 coils on my 99? Are they the same! I will swap those out if I thought it would make a difference. I think If finally threw a code when I was just rolling up my windows so I will check to see what came up in the morning. I also checked all the plug wires none melted. I am still only getting about 7 to 8" of vacuume. IS this normal for a turbo car?

Here is a link to the video we took today. Is there anyway to tell if it is spark or fuel related.

Are you logging any of your driving? I'd be hesitant getting in it much on a base tune. Do you have a fuel pressure gauge in the car? Seems you could be losing fuel when you give it some throttle. I can't wait to see the pics tomorrow.

I do not have anyway to log it.... I do not have Hptuners. I am not trying to get in it. But I can tell you that it seems fine until you come to a stop then it wants to die. It also feels like it is getting way to much fuel. May be because there are a couple cylinders not firing

When I put my blower on the car ran like absolute ****, also had a vac leak, I finally got burned reusing the intake manifold gaskets, changed them... #15vac at idle. Might want to check for a vac leak. If evey thing checks out, get it on a dyno I sent my computer to a sponsor for a base line and it was pig rich, missing, popping ect. After three pulls on the dyno, the tuner was taking a break and i was changing plugs with the car on the rollers. Each car is different and you'll be surprised how far off it can be. PS. your turbo's sound sick.

Thanks, Tomorrow I think I am going to switch the coil packs to the oppisite sides and see if that make a difference. It has been 8 months since the car has been driven and I am ot sure how many times those things have been moved so Maybe I switched them.
