After a day of searching and testing, the car is still messed up
First we checked the crankshaft position sensor, it was not very dirty, but the gap was about 2mm, so we reduced that gap as much as we could.
For a moment we thought the car was back, but it couldn't run idle for a minute without shutting off. Different faults showed up, but nothing I haven't seen before. Most of the time the car would just die as if I turned the key, without any errors.
I decided to place the 'old' ECU in, which I had baked in the oven.
Reset every parameter it had, did a few tests (coils, pump-relays, etc.) and finally a zero'ing of the actual crankshaftsensor. I had to rev the car 3 times to 6000rpm before it relearned it's values.
We checked several other components, timings etc, everything was working as it should.
Took her for a spin and no errors showed up, but the car is still driving quite poorly:
- Idle is quite bumpy, as the car tries to keep a very low idle-rpm of about 650/700.
- When letting go of the throttle, the car bounces a few times.
- When driving in 2nd gear, trying to maintain about 2000rpm, the car seems to dip in RPM.
Only drove her home, so there isn't really much for certain. However I'm still quite certain that the errors will come up later on.
In the meanwhile I am looking for another car, I don't know if there's anyone located in the Netherlands that wants to take her off my hands, willing to spend time/money into fixing the problem. Or willing to help sort this problem, that would even be better.
I'll post again when the faults are back. In the meanwhile I hope someone recognizes the problems with this car, and can give some hints or possible solutions.
