Engine Performance problem
1989 Other Oldsmobile Models 6 cyl Front Wheel Drive Automatic 154845 miles
Hi. I had problems, which we corresponded about in 07. Since then, things have gotten much worse. I have had a problem with the car starting when it wants to. In 07, I replaced the harmonic balancer, cam and crank shaft sensors, the ignition control module, and the mass air flow sensor. It was running well, except that the first time every day I got in the car to drive it, I had trouble getting it started. It would usually take two tries. At some point, late in 07, the Service Engine Soon light started coming on continuously. And the car had been having an ongoing problem with starting. It took 2, then 3, then 4, then more times, 6 sometimes, cranking it over, to get it started. I often had to use my battery charger, that has a jump start, to start it. Then the car, once it was warmed up, got to the point where I could not get it restarted. This problem was intermittent, but then got a whole lot worse and reached it's peak in April, when I barely made it home a quarter mile with my car. I waited overnight to start it and had to jump start it and had a very hard time keeping it running that day. So it sat in my garage for a few weeks, until I got it to a repair facility, and I had no problem getting it there. The trouble code it has been giving me is 41. Now, as to what has been done in 08. The cam shaft sensor, the ignition control module, the coil pack, and the computer brain (which I did myself--what a job to get it out!) Have been replaced. The parts I replaced twice were under lifetime warranty, so the cost has not been as bad as it could be. Now, the thing just had the ignition control module and the coil pack replaced, yesterday. This is what happened afterward. It was very difficult to start the car. It took a lot of tries--I don't even remember how many, and I had to use the battery charger, because it wore down the battery. When it was cold, it ran fine. Once it warmed up, it started to sound like it was bogging down and when you gave it gas, it would hesitate, badly. It sounds like it's missing, almost. My brother thinks it may be a fuel supply problem, but then why the trouble code 41 and why the problem only when it's hot and why does it get worse the longer it runs? By the time it had been running for awhile, when you put your foot to the floor, with it in gear, it was bogging down very badly. One other thing. After my brother had been running and revving the engine for awhile, it did not want to restart. So, since we had been told by the mechanic who had been working on it that it would start without the cam shaft sensor being connected, he disconnected it and it started right up. Then he reconnected it and it continued to start, but it still ran badly and it just got worse and worse. As I said, it starts when wants to, but, despite all that I've done and all that's been replaced, the trouble code remains the same. The mechanic was going to run another wire from the computer directly to the cam shaft sensor, but says the wiring is fine. So, what do you think si going on? I'm at my whit's end! Help! I need to have a reliably running car.
have the same problem?
