This car has been the neglected stepchild for the last three years and I’ve thrown just enough money at it to keep it sort of drivable but never fully committed to tearing it down and doing it correctly.
@fj55-100 invited us to a fun run in St George and I was determined to make this junk reliable enough to take out of town so we set out once again to try to find the intermittent running like crap’ola issue, to date I’ve changed the fuel pumps, fuel filter, injectors, both Knock Sensors, Idle Air Control Valve, Coolant Temperature Sensor, O2, Cam Position Sensor, Air Intake Temperature Sensor, Manifold Absolute Pressure Sensor, Coils, plugs and plug wires, coil wire harnesses and it always runs good for a day or so then starts the intermittent popping issue. I’ve had the data logger hooked up for hours and it always runs good and we believe we’ve finally solved the issue then the next time out the problem comes back (not once could we get it to have the issue with the logger hooked up) so needless to say I missed the St George run.
The last trip out the car completely $hit the bed and started missing and popping so bad I barely made it back to the trailer and at some point in that outing the center support bearing for the front drive shaft started howling, I’ve always wanted to deal with all the mechanical stuff before I tear it down to make it into a pig but the new plan was just tear it apart and replace everything electrical and add the pig skin at the same time. I was looking at the new Holly computer and couldn’t make up my mind exactly how much money I wanted to throw at this so I figured I would start tearing it apart and get to that center bearing to see if it tore up my drive shaft, to get to the bearing you have to remove the headers and passengers floor so this seemed like as good as time as any to start removing the wiring harness.
A friend of mine convinced me not to remove the harness with a sawsall and see if we could definitively find the issue we’ve been fighting for three years and I reluctantly agreed, we had a feeling that something on the passenger’s side was causing my issues so we started unwrapping the harness on that side first and discovered a splice to lengthen the coil pack wires, everything tested good with continuity and no shorts but just for the heck of it I pulled it apart and really started to inspect it with a magnifying glass and noticed that the shrink tubing had ultra-small rub through marks on a couple wires, these wires were taped together tightly and inside a plastic split loom buried deep in and inaccessible area. Still not sure if this was a real issue my friend convinced me to repair the splice and put the car back together and test it before I cut everything out and throw it in the trash (remember I was so over all this I was going to remove the wiring with a saw and forklift and putting all this crap back together was not something I was even remotely considering)
So as it turns out that SOB was right and it was a good decision to put it back together and the car runs well. Now I’m back in the quandary of tear it apart to make it a pig or finish a few last mechanical issues first.
I know lots of words without pictures so this is some from the outing when everything went bad and I barely made it to the trailer.
What you can’t see in this video is this little hill is solid ice and we would get about half way up then come sliding backwards what felt like 50MPH completely out of control. Right about were the video ends everyone is running for their life and I’m flying back down.
