I tried to search but didnt know what to look for. so JDM H22 doesnt go like it should. After 2-3 minutes after we start the engine the car isnt pulling like it should, it becomes slow as hell. If we restart the engine its normal again for like 2-3 minutes. its my friends car, he did auto to manual conversion, and thats when the problems oocured. hes runing H23 tranny on H22. its not the ECU cuz we tried ECU from my JDM H22 which is manual. can anybody help? maybe sensors?

 

You sure everything was lined up when you put the belt on, and did you check your timing with a light?

 

no CELs?

check all the wiring?

did a compression check? (don't take the h22 sellers word for it)

 

no the engine is good. it was runing strong while it was auto. problems begun when he sawpped the tranny. and the car itself is JDM right hand drive and the engine is original which came with car from the factory. it happened after manual conversion.
