so some of u read and helped me out on my thread about my car actin up, especially berry bledsoe lol
so berry i would like some more help from u and others

well i found out wat the problem was, after replacing EVER sensor in the car . it was the ECU
so i put in a A9P, which mine was an A9L, and as soon as i put it in is started up great and runs pretty good too. My only issue is that when i first started it and now ever time as well, the r.p.m. jumps way up to 2500r.p.m. and then gradually settles down. iv done the base idle reset and it didnt make a difference. AND i checked the tps but for some reason it wont go below 4.7vlts no matter wat i do. im confused because it was set perfect before i swapped the ecu. and the CEL just wont go away.
my question is, would the A9P be why its doing this?
or wat else?
