Sometimes when driving my car after it has been on for a little while I feel a hesitation. May I need more ned coil packs? If so how much will thry cost me and where is the cheapest place to get them?

 

Check your codes before you go and start getting your wallet out.

There is a thread saying that Hanshins (the ones that go bad) might be fixable since they get dirty and are detachable.

It might be EGR, or a lot of other things, figure out for sure what it is and then figure out how much.

 

None of my codes are going off.

 

Have you checked them?

 

Yeah man go check out my thread,
