I got a d16y7 turbo i bought the car like this but it studders when i let of throttle or press on throttle have hard time even pulling out. It has cel for 02 which there is none on my car and the other is iacv which i already cleaned... Please help

 

You have no 02 sensors? You have to have a 02 sensor on your car. Theres no other way for it tell what the AF ratio is....

 

Install the O2 sensor and post all CEL codes.

Check the plugs, wires, cap, rotor, and ignition timing. Having no O2 sensor makes the engine run rich and has likely fouled the spark plugs.

 

Thanks will try that.. Ill get back to you guys
