Ok so my car was running fine after i did the mess under the intake. After driving for a while my car now sputters really bad as its idling and when im driving my check engine light will go off and on, sometimes in first gear my car will jerk forward a bit. Ive sprayed carb cleaner checked for vacuum leaks didnt find any so everything is tightened up good, tried to do a stomp test but nothing happens when i do so i cant get any codes to check where the problem may be. I have no clue were to start here. o2 sensor maybe? dont think its ever been changed, maybe a problem with me ecu?

Decided to try it again this morning and now it starts goes to about 2krpm then dies instanly. Maybe my icv is dead although it seemed to be keeping it alive last night it was just running rough, engine shaking, sounded like random missing.

Why does nothing happen when you do the stomp test? Are you doing it right? I didn't even know these cars had a way to check codes like that until about 6 months ago.

I couldn't tell ya. I press the pedal to the floor and release 5 consecutive times fairly quickly but not too quick and wait nothing happens I've tried over and over but nothing

Key is in the on position, cel works just test doesnt happen idk why but im guessing my head gasket is blown due to the fact my oil level is higher than usual and the oil is realy runny ive also lost some coolant with no hose leaks

so i guess im going to gather the materials to do this job myself as i dont have the money to get a shop to do it.

run a compression test first. it could save you a lot of money

I'll do that this weekend. Another thing my temperature guage has never worked since I've had the car it goes from dead to blue when I turn it on but never moves from there so I guess if my car overheated and it is the headgasket I wouldn't have known although I never seen smoke coming from the hood... So since I may be spending some cash fixing all this what should I check to get my temp guage to work.

For what its worth, on my 91 M42 for the stomp test I have to stomp 5 times then hold it to the floor for a 6th time for the sequence to work.

You might just have a missing or stuck thermostat. That's the usual symptoms...either that or a bad sensor.
