Thank you! I am trying to get used to this message system. I was unable to post a reply to someone yesterday. I have a vacuum egr that has been replaced.
😄 No, the problem hasn’t been resolved yet! I just couldn’t figure out how to respond to the question for some reason.
Here’s the update in this ongoing mystery saga...and at the end, I explain my reasons for trying so hard to fix this car, even when it didn’t make sense...
The Cadillac is at the smog repair shop, but it idles too high to test or fix right now. They want to know about the idle speed motor which has already been replaced twice.
Here are some symptoms: I have noticed after 5 years that after the battery is disconnected or drains, the car will drive fine for 20 minutes and then surge and sputter and cut out. It has consistently done this for 5 years, no matter which mechanic thought they fixed it (they don’t drive it for 20 minutes).
In the last 5 years, 3 backyard mechanics and a shop have worked on it.
They have replaced parts, some of them 3-4 times. Here is what I found in my receipts for the last 5 years. And I know I have lost some receipts. The car supposedly passed smog the day before I got it. It drove fine around the block. I took my back yard mechanic to check it out and he thought it was in good shape, so I bought it. It has not smogged since then.
Each mechanic thought they fixed it multiple times. I would drive it 20-30 minutes before taking it to smog. Just as I would arrive it would start surging and sputtering again.
We got a code once that the ECM/prom was not getting signal. And the first star smog repair place that I just now took it to noticed some spliced wires under the hood. He refused to accept it and sent me to A1 Electric smog repair. I hope they can figure it out.
Here are the parts I found in my receipts, many that have been replaced more than once. And I lost a bunch of receipts.
5 fuel pumps, fuel pump relay, fuel pump relay connector, fuel line, fuse holder, 4 fuel filters, Throttle body fuel injectors, Throttle position sensor (twice), Throttle body gasket, Throttle body (tps?), ECM control module (twice), EGR gasket (twice), EGR valve (twice), EGR valve control solenoid, idle speed control motor (twice), JTT 2824F sensor, spark plug wires, spark plugs, AC Delco parts 214-2287 plus another part, Brake booster, Fuel Sending Unit (twice), vacuum tubing, TBI gasket, Orifice tube, crbcin, 3 V belts 219-586, air smog pump, O2 sensor, wire harness connector plug socket. Someone re-connected a ground to the gas tank.
In addition to all that, after one of the earlier mechanics told me he fixed the Cadillac, I replaced the suspension as a result of the steering being loose. I replaced the steering gear box, front Pittman arm, front idler arm, upper & lower control arm bushings, front upper and lower ball joints, steering gear seal kit, inner tie rods, outer tie rods, adjusting sleeves, sway link kit, tie rod ends, sway bar links, and alignment.
Several years ago, once I got the green light from my mechanic (😅) and got the suspension done, I was so exited the car was finally fixed. I breathed a sigh of relief and joy as I drove
it off their lot...but...the steering was still loose, and the car surged and sputtered and cut out...again...before I could even drive it home.
It is true I have wasted time and money on this car that I probably shouldn’t have. I think it’s kind of like an addiction to gambling. I keep thinking...the car starts and runs good for 20 minutes. It has already had every part replaced in it, surely someone is going to find the source of why it surges and sputters after 20minutes. And then I’ll have a nice running beautiful car. And I do have an emotional tie to this car. I bought it for my son for his 18th birthday because he was crazy about it and wanted it so badly. And I wanted leverage past his 18th birthday. I told him I would put the title in his name after he was tested and stayed clean from pot and alcohol for 6 months.
Pot and alcohol made him suicidal and we almost lost him.
The car never worked right and it was worthless as leverage. But after 5 years, our son has finally been sober for 5 months. I would sure love to surprise him with this car finally working, after he has been sober for 6 months!
