im using a check valve and its 2 of them, but thats what i used before i got the 880s and it worked good. another thing is i used to have my stock intank fuel pump and a msd inline fuel pump that came with my drag kit, and now all i got is a 255lph walboro intank pump

 

Did you try just not using the check valves and use the stock map sensor.Try at least. Also check to make sure your Map sensor was hooked up correctly again. You too the stock off then added a 3 Bar map sensor and now back to stock again? Just check the wiring to ensure it is correct and no shorts or mixed up wires. Also again like I said take the stupid check valves off and just run the map sensor like stock. I have known people where the check valves cause this problem too, also besides just the check valves I have known people to use the Missing link and have it clogged up. Retrace your steps.

 

yeah, i tried just using the stock map sensor like u said and the car idled shittier for some reason. if i messed up on the injector wiring, the car wouldnts start would it??

 

Yes it would but it would idle rough like on 3 cylinders, I had a wire come loose on one of my injectors before and it ran terrible. So chekc your injector wiring also.

 

ok, i checked and everything looks good. do u think it could be before when it was running fine i had a inline fuel pump that came with my drag kit and the stock fuel pump, and this time around i got rid of the inline and the stock fuel pump and im only running a 255lph walboro fuel pump??

 

 

help this guy

thanks!! i found out something new, when i barely turn on the car, it doesnt go lean but when i let it idle, little by little it starts to lean out

 

Why are you running check valves with the AEM EMS anyway ?? The EMS needs to see boost in order to run properly.

Its unclear but are you using a rising rate FPR ?? You don't need that either.

The AFR sensor that you have - is that a wideband ???

Where did you hook the signal from the 3 bar to the wiring harness. Did you reverse it back ? Could the stock computer be reading the wrong signal because your stock map signal is not getting where it needs to go ?

Could it be possible that you F*^$&D up your engine before if you were boosting without letting the AEM see boost ?? 880cc injectors are good for like 400+ hp and trying for that on a stock bottom end is asking for trouble.

I'm not trying to be an *** but to help ask some questions that have not really been answered yet and that you should be asking.

Do a compression test to see what your numbers are.

Just my .02c

 

did u read my thread at all?? i took the ems off when i took off the 880s, that means i have my stock ecu on, i have my stock fpr, i have no wideband just a cheap autometer a/f gauge, i still have the 3 bar tapped into my map sensor its just not plugged in, i dont have a stock block, lol everything u said i already posted.

 

a shot in the dark. were you running a resistor box on the injectors?

didja remove it when you went back to stock injectors?

 

well i ran individual resistors for the 880s but when i took out the 880s and put the stock si injectors, i got rid of the resistors

 

any suggestions??
