my car hasitate when I turn on the AC at neutral and low rpm the engine want to shut off but it works at high rpm . I checked it with obd scan it show p1316 and p3004 cylinder number 4 misfiring. what to do ?

2002 xj8 .

 

Your misfire is intensified when you turn on the AC...so fix the misfire, whether it be a bad plug and/or coil pack. I'd replace both. The P1316 is a result of the p0304 in emissions.

 

okay. cylinder number 4 is in right side back of the engine?

 

Right side, rear most.

 

thanks .

 

Right side from inside the car !!! Don't know what Country you're in!!

 

what you mean exactly? if you can't be helpful don't be negative I'm asking about the cylinder exact location you come then say right side from inside! I don't get it .

 

Right and left is determined from inside the car, not from standing in front of the car. Negative??

 

I didn't ask where's bank A I do know that right side mean from driver view not from standing in front of the car . your first post is not related to my topic . maybe you misunderstood when I said rear of the engine? I meant the last cylinder in bank A and cylinder number 1 is front of the engine.

anyway is not worth to make it big deal we are all here to spend good time and share knowledge help each other that's all .
