Over this winter I over hauled my car, and redid my timing belt plus installed a turbo kit.

I have the car running and idling now running on a Mega Squirt PnP with the base 9093 no AFM map (I am using the GM IAT).

Well this si what my idle sounds like, I went around back because it is more pronounced out the exhaust, but I have the same time of stutter up front.

is this a misfire? does it sound like my timing is off? or my timing belt off by a tooth?

I followed the MS instructions to lock the timing to 10 degrees and then adjust the cam angle sensor to 10 BTDC, then move it back to -10 degrees.


Sorry about the lifter noise, car sat all winter and it tends to do this to me...

thanks!

You have to tune, you know. Why don't you head over to the MS forums and do some searching.

Have you installed a WBO2? You should.

yes I have a wide band, I just wasn't sure if this was a tuning issue or a timing belt issue.

Never hurts to take one more look at the timing marks to make sure.

What does the WBO2 read? You should be shooting for 13's to get a smooth idle. I'm almost positive it's a tuning issue. The MSPNP basemap is designed to get you started. It is hardly a finished tune.
