I have made some improvements to the problem but here is the issue. The engine runs a bit rough for the first 20 to 30 seconds. So far i have replaced the following, some of which have helped improve the situation.....
new Pre cat O2 sensors
new mass air flow sensor
fuel additive (barhdohls) ....seems to have helped
new fuel filter
new cam positioning sensor
Of all of the above the oil change and the fuel additive seem to have helped the most.
Any other thoughts??
Or the Idle Control Valve, also a common complaint on these engines.
