please please help! revving problems!
ok. i have a 1989 ford f-150 with a 302. i just put a different motor in it, and here is my problem. sometimes when i start it it will run good, and rev to at leat 5,000 rpm's, then i shut it off and it will rev real slow to 3'500 rpm's maybe if i'm lucky. i have changed fuel pump,fuel filter,coil,distributor,ecm,tps. my comprssion is 125 to 145psi. i have been at this for a month now and i don't have no clue what else to do. I really really need some help here. please any suggestions i will try!
