Ever since I got my engine put back together with the new cam, I haven't been able to get it to run right. It won't idle right about two thirds of the time. I pull up to a stop sign and if I don't play with the gas pedal for about 5 seconds it will die. After that it will idle all day. Sometimes all I have to do is put it in gear from park and it will die. At cruise speed it will just start bucking like the power wire to the computer is being disconnected for about 1/2 second at a time. It bucks so hard I'm afraid it is going to break something in the drivetrain. At medium acceleration, it runs great most of the time but if I put my foot to the floor it vibrates so bad I can't even see out of the mirrors and at about 4500 RPM the check engine light comes on. When I pull the codes it says low and high voltage at the TPS at the same time? I'm thinking the vibration is coming from misfiring. I've changed the TPS, the computer, the dist. cap, rotor and plugs. I ohmed out the plug wires and they're ok. I've got the TPS set @ .52 V at idle and the potentiometer is working. When I changed the cap this last time, the contacts inside were totally covered with what looked like soot from a tailpipe?? Could a coil taking a shit cause all this? I have a new fuel pump, both filters, had the injectors cleaned and flowtested. Fuel pressure is set at 45 PSI. I have spark at all plugs however it seems weak. I have to get the end of the wire right up against the header before I can see a spark and then it just doesn't seem like it's very stong. :cussing: Sometimes I can drive for an hour or more with no problem, but I can park the car long enough to fill the tank and when I restart it it's missing so bad I'm not sure I'm going to make it home. I'll get a mile or two down the road and it will just kind of pop and all is well again for a while.I've got a new coil on the way from Jegs but it won't be here till Tuesday. Sorry for the long post, but I'm at my wit's end.
