Off idle stumble & while cruisin...

[ttypewhite]

3 things to look for.

1) Check your hose from your turbo to your mass air for any rips
2) try another mass air
3) try a different set of spark plug wires
I had that same stumbling in my T-type until I put in that power plate from RJC and it ironed all that stuff out. Its cheap and well worth the 60 bucks.

hey chris
i have red stripe injectors they are hard to control . i started with
48 psi and was running very rich with no stumble (o2 820 on the
scanmaster @ wot) the car runs its best @ 39-41 psi depends
on the weather.i have hadit as low as 36 psi . i bring it up 2lbs to 37 - 38 psi and the stumble goes away any thing higher than 42-43 and the car suffers on top end . the leaner the mix the meaner the car (faster) keep the o2 between 750-780 @ wot .750 being leaner. the tps .42 @ idle 4.7- 4.9 @ wot with ing on and the car off. remember you cant read the o2 volts unless the car is running @wot.(top end) .the numbers will be all over the place any other time.good luck .

Clean Filter?

Assuming that you have a K&N filter with a forced air setup, it is possible that dirt or whatever may be a contributing factor. Try cleaning the filter. If that and everything fails, the Translator suggestion is a good one.

Any luck yet?

Well gonna try another set of plug wires (MSD) and clean air filter.
I'll let everyone know what happens tomorrow.

I think my next step after that is swap my INJ back to stock and run my old thrasher chip.....

Well. DId the following as my last resort.
Cleaned air filter, New Plug wires. (2nd set), cleaned terminals on coil pack and took out my red stripe inj and JC chip.

Well...................

The car is back to normal.... No stumble.... I know i did to many things at once so hard to tell what happened if it was INJ CHip or any of that other stuff but the car is running much better with my Thrasher and stock INJ in there and all that other stuff straightened out. Thanks all for the input and i hope this car stays like this.
