friend had some1 program his car 95z28 obdI. now his car is completly dead off the line and does not run like it should at all. the programer used lt1 edit on his car and reverted back to his stock file and car still ran like ***. he sent his pcm to pcm4less they tuned his car originally. he was still having this problem after he got it back so he tried another computer from a perfactly working car and it still was messing up. he replaced the opti, new tranny,new plugwires,plugs,diff mass air, new map sensor new tps sensor, cam sensor wireing harness, and cam sensor. he tested the fuel pressure regulator at idle and its fine.


if he had donuts on the car at a dead stop it would not peel tires.
he gets on it from a dead stop and it feels like its driving in 3rd gear when its 1st. its worse down low then up top.

 

Is there any leaks in the intake ie the elbow

 

no leaks.

 

compression check?

 

he tested his fpr and pump
i am sure he did a compresion test but i will ask him a lil later today.
