Default whats happening? help

Okay, so this is something that has gotten worse and worse. So a few months ago, my car started backfiring every once in a while and fast forwarding to now, it will backfire and stall. What happens is this:

I start the car, everythings fine. I drive a few miles taking it easy, and things are good. If or when I have to idle at a light for more than a minute or so, it starts idling rough and the rshared_pm needle is jumping to 7grand then 4 then 1 then 9, its all over the place, if I try to give it gas, it might save it or pull it outta the stall, or it will stall and Ill have to restart it. SOmetimes it wolnt start like it was flooded or something. I just need some suggestions here guys.

FYI, this is a pretty much new motor. I got it from Canada via Japan with less than 30k miles on it. Drew over at Darkside put it in so Im not doubting any of his work, I just think that something is failing here and I dont know how to handle this right now. THanks guys and gals

Please ask me anything you think will help me put an end to this. Also feel free to call anythime 727-504-4802 Kai

^Id say this. Boost leaks wont be intermittent..and I think the ecu gets the r-pee-m (lol stupid tr) signal from the cas, right?

It's not the idle air control, they either work or don't and wouldn't make his rshared_pm gauge go crazy. This issue is more than likely a cas,igniter, or ecu problem...

Here is an idea, instead of guessing, why not bring it back to Darkside for an expert opinion and fix?

yes it does except i have left messages and called for months. I cannot get ahold of Drew. I used to stop by but noone was ever there. I didnt know what happened, but lately Ive driven past the shop at night while Im on a delivery and seen his vehicle there or saw the bayt open, but I never have my car with me.

Drew if your reading this..please call me tomorrow. Id like to come by and have tyou take a look at it.

Thanks again guys, and regardless of what happenes, the next step for the car is to look at the cas. THank you.
