well here the problem my car runs perfectly when im going slow or even accelerating slowly,but when i realy punch it my car has a slight jumpat high rpms,very small.when i was shifting fast from 1st to 2nd,my car had a slight jump in 2nd gear.could it be my spark plugs,i have the ngk iridium ix if that helps,they are moderatly new.maybe 4 or 5 months.stock ignition wires

 

i thought the iridium's are bad for DSM's?? i might be wrong, i use ngk but i think i saw somewhere iridiums are no good in these cars

 

thats what ive been told,but could that be the problem?

 

what do you mean by jump. Like the rpms go up alittle faster than they should and your not really going. Almost like you just rev'd it for a sec. because if thats the case it could be the clutch

 

are you loosing any performance when this happens? is it like a hesitation/stumble in the engine before it gets on it? you have a very vague description of your problem, with some more detail we can disect the problem better

 

i fixed it,it was the plugs,iridiums are bad

 

Yeah thats a common one. Good ole NGK classics are the best : )

 

hey, i was right lol, i thought i heard the iridiums were no good lol

 

its nice to see a thread that confirms it as well. Because i had heard of people having problems with them but now its good to see where it was definetly the problem. Thanks for letting us know

 

no thank you guys
