sputtering, backfiring, and misfiring
sputtering, backfiring, and misfiring
OK, here is my issues... I NLS'd today and missed the gear. i revved high but hit the limiter. after that, my car started misfiring just as it would on a cold NLS. i shut it off, tried restarting it, but no change. sounds like a subaru. popping backfiring and misfiring. i changed the sparkplugs, gapped them to manufacturers specs. i have recently put a catless DP on. I'm getting p0107 code. also there is a lot of liquid in the exhaust, doesn't smell like coolant or gas, but there is a lot of it... whats wrong with my car? i posted this in a few places so....
anybody?
anybody?

Do you have the RPD?
had someone with a similar problem sounding like a Subaru including the misfiring, but nothing dealing with the NLS. He busted his intercooler once and replace it with a PVC pipe temporary. Then his mom put 89 Octane in his fuel tank, after all that on his birthday ready to go to SC to visit a couple of friends. His car wasn't the same again. Done all straight pipe w/o sensors, driven it hard most of the time like he stoled it, and replaced his spark plugs, but nothing was ever change. Now it sounds like a Subaru, but he got rid of it a long time ago before I gotten my 09 SS/TC.

so, ended up blowing the map sensor, boosted to 43lbs and threw a few rockers, everything is being covered under warranty. what a ride. lol i knew the pop i heard wasnt a good one.. haha, gettin her back 4-30-10. cant wait.
Exact same thing happened on a friend of mine's SS/TC about two weeks ago. Missed a gear, and busted his rocker. Odd. How do you know you hit 43lb's? Cause that ain't happening on the stock map's readout wise. And yeeeeah.
I dunno because even if he is talking 43 lbs absolute pressure that is still 28.5 lbs guage pressure.
That's what the tech said he read from the computer... I dunno. Sounds kinda high, I'm just relayin info... It will be back on the road tomorrow. It'll be catless again soon as well.

Both for the blowing of it and the fact that they are covering it under warranty.
