109383, Backfire/back pressure
Posted by eclipse420ags, Dec-31-69 06:00 PM
So I got up and cranked my car this morning and it was super loud all the way to work, when I got there popped the hood and saw my dp was broke off from the turbo flange. I was gonna let it sit there and idle for a little while to let the turbo cool but the engine started bogging down, finally cut off by itself then backfired. Is this because it didnt have any back pressure at all? What does it sounds like to yall?

Search back pressure. You will learn something I guarantee it.

Whats your wide band reading? If you don't have one try reading the plugs. I wouldn't think so but mabey. What fuel pressure and injector cc's?

Might be because the up stream o2 wasnt reading and it created the motor to bog and then eventually cut out.

yeap. front O2 was reading lean, causing the ECU to dump fuel.

That makes sense it was really bad before the car heated up that would explain why.
