ok so i got a 96 bronco with a 302 auto 133k. for the past month or so its been starting hard. 1st start of the day it starts ok but kinda stumbles over itself but then its fine. if i let if warm up then shut it off and start it back up. its fine. but if i let it warm up shut it off and try to start it about 1hr later it cranks for about 7 sec, then finally starts. Also i can feel a real slight misfire at low rpm's. either at idle its like a small vibration in my seat or around 1100 rpms driving. I have already replaced, IAC,FPR TPS, MAF, ICM, EGR valve and sensor, plugs, wires,cap,rotor,coil,air filter,fuel pump relay, pump has 40psi so its good,new oem injectors, cleaned intake, alternator and battery are good, as good compression and there aren't any codes. might be a few things I'm forgetting but i can't figure this out. any help would be appreciated thanks.

 

you might just have a bad motor. replace it or rebuild it. if you replaced all that and the problem is still there than its a major problem. do you dog it out alot? that might be the problem. i got an 87 bronco and that happened top me so i just rebuilt the motor now its like new

 

no it has plenty of power still really gets up and goes. just starting and around 1100 rpm it has a problem
