its a h22 with aem and external fuel system the car started running weird so i changed plugs wires re gaped so on and so forth but no fix what happens is if i hold the throttle stedy at 2000 rpm it kind of bounces up and down a couple hundred rpm in like a pulsating way and if i go steady at 3000 same thing pulsating but the intervals are a little further in between if i go to 4000 same deal with longer pulsating intervals in between if i put the car in gear and drive it also pulsates it wwill still rev up but it starts popping at higher rpms know i took the plugs out agin and noticed #1 cylinder is running rich #2 cylinder running rich #3 cylinder looks to be running lean not as sooty as the other cylinders and # 4 cylnder is running rich i checked spark and it is all good in every cyl so im thinking my # 3 injector is not working right ,how could i be sure ? any input would help

 

ok i took the car out to the high way and noticed that as i give the car gas my air fuel meter goes lean immediatly and the car starts poping and has no power but if i give the car gas slowly it will still rev up any input?????????my fuel presure still rises in boost though

 

are they peak and hold or saturated?

 

did you just slap em on and drive? It would usually just run like **** if you dont lean your car out with a VAFC or something. Talk to your local tuner and setup a dyno session to tune your car.

 

they are peak and hold and the cars been dynoed and tuned for over a year and was running great maybe bad gas or filter the car is turbo if that helps thjis pos aem ems dosnt flash a engine code so you got to go through the whole car and find whats wrong

 

did you just get the injectors or have you had them in the car for a longer time with no problems, kinda explain here i am not sure if you just put them in.

 

the whole car been together for a year
