Where are you located? Check base timing, and load the base map that AEM supplies to verify its some other problem and not the ecu. Reason being is who knows what was done to that tune before you bought the car

 

fix them and sell them, contact t1, buy ID injectors


live happily ever after

 

Check grounds as well as the battery. I had a bad battery ground and it was causing me to misfire.

 

`The car have resistor box???? one of my costumer burn one driver on the aem..

Did you put the timming gun???

let me know....

 

Check the ecu ground behind the head may be is loose

 

the newer injectors solved some of the problem but there has to be some kind of discrepancy in your timing map on the EMS. a retune might be beneficial and shouldnt cost too God awfully much considering you already have a map to work off of

 

yeah we put the timing gun and theres still the 10degres off the seconde and third cylinder. I did not check the ground behind the motor. can the ground really messup my timing that bad?

 

right now i paid 840$ at my tunner for 2h of tunning and 5-6 of mecanique and he found NOTHING. I got my car out of there and tought i could fix my probleme myself. changing the injectors took away the rough idle and the miss firer, but the timing is still off

 

Check your coilpacks, and spark plugs. If the injectors are a known problem replace them. Did your tuner try to retune the ECU with the old or new injectors?

 

everything that is listed at page 1 is without the new injectors, so i would need to try once more with his ECU, but tomorow i'm going to try a new map to see what happenes. spark plugs a new and the coil pack seems fine
