Every time i accelerate, it happens to just lean out. This issue came to light one night that i over boosted and the dipstick popped off and i threw 4 codes

Has anyone experienced this? Or can shed some light on this?
I cant even make it up a slight hill because the rpm just drops

It looks like you may have just filled up did you get a bad mix maybe e50.

 

Tested it, it's not the gas. Maybe fuel pressure is lacking

 

That would be my bet if fuel is ok.. especially without any load.. get a gauge to test fuel pressure to get an idea where its going to get better idea

 

I would check fuel pump relay, and the fuel press reg vac hose first. also you are throwing code for system too rich and front O2 sensor, and evap so since you over boosted it sounds like some hoses might be pooped off.

 

Thanks guys, will do

 

I think it is your fuel pump relay put the high beam relay in the fuel pump one and see what happen. I had the same thing happen to me but it was ok after I shut it off and turn it back on but the sel will stay on.But mine would not let me boost pass 12psi. Good think for the aem wide band.And sense you can make it up the hill you might got a vac. Leak like m86 said

 

I will be going outside in a few to double check, thanks again guys

 

weird that they didnt change the FP relay when you got tuned. I thought that was like a must do for the X's.

 

looks like i still have the black fuel pump relay

 

you should change the black MFI relay to the grey one as well! Just a suggestion.

 

 

deffinately need to get the Blue Relay or atleast the Green one.

 

I'll stop by the dealership tomorrow

 

Did u try switching the relay just to see if is the fuel pump relay problem all the black are like the same relay.The high beam one would be the best because we use that less.gl
