Car running rich all of a sudden.
okay, so i got my car tune can running good for a few days. air fuel ration around 14 and 13s... i took it out and done some full throttle runs on the street, came back and turn the engine off and went inside the house for 20 minutes and came back out to drive my car and my car is just running real rich around 10 to 9 airfuel ratio. i can't even go into boost because it will bogg...i am running mega squirt by the way...so what can cause the car to do this? running super rich.

[QUOTE=Braineack;236129]you has leak!

you have megasquirt, so running off a MAP sensor, it's not going to register any leaks in the IC pipes after the TB. You could have a gapping hole in your pipes and still register 20 ~hg.

I dont have megatune installed on this computer so i cant walk you through checking it. maybe Scott can outline the menu you have to go to.. |
From time to time my IAT sensor would lose connectivity with the plug and run rich.
