Hi guys, me again doh!
Sourced a new AFM for the Z which seems to be working fine which is great. What I did notice is that the car is now idling really inconsistently. It's all over the place.
Here is a couple of video of the idle, recorded one after the other it sounds like it loses a cylinder on the second video too.
Things I have done:
- Checked fuel pressure (fluctuating between 32-35 PSI)
- Checked for vacuum leaks and subsequently replaced a few hoses.
- Performed all of the checks on page 38 of the EFI Bible
I did find that the 2nd circuit test which is on page 48 (screenshot attached) resulted in continuity at both part and full throttle, which points to the throttle valve switch - could this have something to do with the inconsistent idle? I checked the connection and pulled off the plastic plate and all looks okay?
Any thoughts would be greatly appreciated - can't wait to get rid of this pesky efi system.
