Ok heres the deal. I took the Y8 out of one car, it ran perfect as an auto. I put it in my buddies car with a manual trans and now it has a terrible hesitation under a load at low Rs. Engine has a fresh tune up and is gettin plenty of fuel. The only thing that has changed from old car to new is the intake manifold and throttle body. There is no vacuum leaks and no wiring issues.

Could it be a bad TPS?

Any other suggestions?

Thanks in advance.

 

No one?? Damn people come on.

 

Can't believe no one has anything to say.

 

thats what happened to my car i got an obd1 d15b vtec and it was throwing a tps sensor and a map sensor code.. so what i did was disconnect the batter and took off the tb and re adjusted the tps and hooked everything back up and it ws good to go.. and when i checked the CELs again they were gone and it ran fine and no more rough idle to it..

hopefully it works for ur car..

 

Any CEL codes? Does the ECU match the engine?

 

No CELs, and yes the ECU matches the engine.
