hey guys ,my car is not standing at idle .after geting warm my car is droping at idle and turns off most of the time ...its cold here and im runing ngk num 9 plugs with hks dli .wat cud be the reason ? This has started since last week .also note ,my afr goes to 10.5 when the idle starts to drop . Thanx

 

I'm having the same issues. I have been searching the forums here for the last hr...this is some of the potential problems I have found...Most people blame a vacuum leak of some sort, some say coolant temp sensor, dirty MAF, spark plugs.

 

i dun have a maf ,im using map ,so il do the boost leak test and than change my plugs .but ive been told to clean my throttle body first so il do it tomarow .lets hope for the best .

 

Any word on what the prolem was? Sounds similar to what mine is doing........
