Title: Injector problem
Post by Executive on Feb 26^th, 2006, 12:02pm

Hi All,

I have a 24V Cossworth from year 95'. The car working properly, but the rev at idle always moving a bit up and down. I have an OBD lead, and I know the followings:
- revs moving between 690 and 730 (the engine rocking a bit.)
- sometimes small explosion occured in the exhaust
- iacv working around 33..36% at idle,
- left side o2 show lean (sometimes) and the right shows reach. (I have DTC for these, and I can see it)
- I have replaced the fuel pressure regulator, and the whole vacuum system is ok.
- LTFT show left side +6..9%, right side -6..9% at idle.
- stft both are around +2..-2%.

Does the injector itself able to do this symphtom?

thx.

yes, the MAF is ok, the curve moving together with the rev. it is connected, I am sure.
