fluctuating timing problem
fluctuating timing problem Anyone ever have a problem with timing spuradically jumping around causing surging?
I think he has a faulty tps even with the engine off and ignition on the tps will read between 7 and 15, something seems to be causing the TB to fluctuate changing map readings and consequently timing.
No se lights

Its drive by wire, I noticed the map readings will dip spuradically under wide open when it does it. Its like the throttle body isnt staying open all the way and the butterfly valve is fluttering, there is no KR.
It will do it under part throttle also.
This is on a boosted motor.
