Ignition Misfire fault.

Thanks Woodchuck, what needs to be replaced to fix this problem?

Depends on what caused it. It's just saying it detected a misfire.

cap, rotor, plugs, wires, coil, etc. Would help to know what kind of car you got!

I have 99 VW Jetta Wolfsburg edition 2.0L(old body style). The tune up was done at 60,000 miles(Spark plugs, plugs wire, cap and rotor was replace) and car now has about 75,000 miles. There is a starting problem once every two weeks and when that happens the idle is rought but get to normal after I gas the car for couple of times...

Thank you

Coil.

Thank you very much

One thing I forgot to ask, is it really difficult to change on 99 VW. I bought it online and wondering I can change it myself. Please advise.

Number 30 Torx & 10mm wrench.

Thanks Woodchuck, Just wonder if I need to remove top grill please see the pics http://68.36.235.247/3.jpg copy&paste. I do not see any otherway access back of the screws holding ignition coil.

Just pull the rubber seal off and then slide something like a small 2x4 to hold the plastic cover up enough to get your hands in.

Hello guys, I am able to changed ignition coil successfully. Now one porblem check engine light is there. I have drove some 60 + miles but it is not going away. I also had p0440 code which was caused by lose fuel cap. Now I am just wondering if there is an easy way to reset the cars computer and see if the light come back on...Thanks again

it took a good 100 miles to reset my loose fuel cap code. keep driving.
