i did the coolant temp sensor, did nothing...next is air temp...then ill do 02 sensors(both are fairly new tho)

i did the air temp and the ignition module...still doing the same thing...next is the 02 sensors, and if that doesnt do it i dont know what will

when you put the clutch in,was there a ground strap that one of the bellhousing bolts went through?

before spending the money on sensors you need to have the computer scanned for codes.

Are you still running the stock MAF? If not, which one are you using?

The best thing to do is like Lee said and scan the computer first. It will be alot cheaper if you diagnos it instead of swapping parts, that will get expensive. Looks like a multi meter is going to be you best friend for awhile to find the culprit.

yep!,I've BTDT!,that's why I asked if he checked his voltage @ the TPS and all,I went through that,threw ALOT of money at my car,and it was a non-grounded TPS that took me 5 minutes to fix!

Thats what I'm talking about. I have learned not to guess and take my time and check everything if I have too to find the culprit. Thats the type of stuff that would grip my butt is when I would guess and keep getting it wrong and it be something that simple as not being grounded.

roger that!,first investment to make when dealing with any of these cars,IMHO,is a digital voltmeter!

I've had a bad mass air sensor cause about what your describing . Car would run fine when cold or driving it easy but give it any throttle and it would miss and shake car badly . Code reader wouldn't read that it was bad.
