I'm in the ogden area, I have a 90, 35th anniversary sc. 134k. Clean with a few blemishes. Overall she's a 7 outta 10. It's my 4th sc. Others I've lost due to divorce etc. Anywhoo... this black Beauty... I just can't get it to act right. I'm think crank sensor, or dis. Your thoughts? Anyone in salt lake or ogden area care to help out?
Here's what she does.
Crank, crank, crank little throttle and fire.
Sputters, bogs the rpm's and dies.
Give her throttle she screams and revs great!
Let off the throttle and she bogs down, up, down and tries to die.
No up shift light while cranking btw.
Unplug MAF and it seems to smoothen out idle, haven't taken it down the road this way yet.
Just swapped out the HB due to a stripped pulley bolt and got rid of the slight wobble.
Ok, so a little testing goes like this....
Tried to get her to go down the road, ok cool.... she takes off, and shifts smooth, then like it bucks and Jerks and won't shift like it's confused on what to do, no matter the throttle. More is bad, less smoothes out but will not shift due to rpm's I'm guessing.
Let's see... oh, I can hear the fuel returning into the tank, but it's like a surging, not a constant flow. U can hear it in the car, rather annoying I might add... it's a gush, gush, gush, gush... etc
My thoughts are:
1- crank sensor, or
2-dis and the stupid dielectric grease, or
3-bad coil pack? Questioning that one due to the way it revs up and don't miss.
4- fuel pump and low fuel pressure? Not sure yet on that one.
5-bad ignition switch. Due to a 71 Plymouth GTX I had years back, it had a faulty ignition switch. The car ran like dog crap unless I turned the key ever so slightly. Then she'd clean up and be back to screaming! I have an 89 tbird lx in the back shop I was thinking swapping ignition switches out to eliminate the possibility.
After searching, and studying, and searching and more searching. I can't come up with an answer, and lack of parts readily available to swap out and assist with troubleshooting just sucks btw! No CIL's. Anyone maybe have some insight? Anyone near me able to maybe come have a few beers and give her a look over and see if I'm missing something so stupid I should be kicked in the cherries? Thanks all!
