Post #1
So I bought a car that needed a head rebuild, had that done, added PeterT cams, (stg 2 inlet and 0.5 exhaust and timing advanced) had the bores honed and reringed. From the start it just didn't want to idle at all. Peter was
surprised it didn't as others had done so with no problems.
All sensors checked and idle stepper cleaned.
After driving it for a while we put the timing back to standard and that improved things a little but not enough to trust lending the car to mug punters. Although the standard ecu had learnt enough to run the car most of the time I pinned my hopes on an aftermarket ecu.
After saving up I bought a predator plug and play ecu from the UK and had someone install it but had no joy with that either. Similar symptoms shone through the two different management systems. These are the ones that make it hard to diagnose.
A ) runs perfectly 90% of the time, pulls really hard.
B ) runs like the stepper motor is shagged the other 10%.
C ) has stutters that don't correlate to any rev/load/orientation
parameters.
The one time it does do it's stalling trick more often is if the car is hot, I shut down and go to the shops, and when I come back it's not able to idle, so a 10-15 min cooldown.
The mechanic can't get the fault to rear it's head to try and find it and I have lost ten years off my life expectancy worrying about it....
So after reading stalling articles on this forum for the last year or so the only one I can find that sounds the same was a chap called Tomtom? that had to replace the loom to get rid of his stalling problems.
Another solution might be to have traditional standalone management installed that has it's own loom?
Could it be anything else?
When she's good she's great but when she's cranky I could just cry. Help me save this beautiful but volatile relationship!
