Ok so I was going back home from work and I wanted to push my baby stronger than usually. At 4th gear doing around 110 mph my SES started blinking and I felt loose of power. I know that was misfire. After i slowed down it stopped blinking. When I got home i pulled code and it showed me p0302 which is cyl# 2. Is it possible it was misfiring because i had almost empty fuel tank? If not, what is the reason that it misfires at WOT not other other load? my ***** is 99 and has almost 100k miles.

thanks for any info

 

change your plugs recently? if not ... i'd try that and see if it helps.

 

Check your fuel injectors.

 

check sparks....btw, what is WOT.?

 

Well first off you were putting your car under a lot of pressure so you are creating problems by driving like that. But your problem is probubly just a spark plug if shes not that old and only 100k and you driving like that I would venture a guess of a bad spark plug.

 

Wide Open Throttle.



Are you on the original coils? 99's are well known for faulty coil packs.

 

Coilpacks.............................

 

yea. cyl 2,4 and 6 have old coil packs (100k miles). I didnt have a chance to switch them around and see what happen. Maybe Thursday

 

I had a similar experience about 1 1/2 years ago with my 95 SE, then with just over 170K miles. It had been years since I had opened it up, so late one night just for fun I cranked it up to a little over 100 on an empty highway, and shortly after noticed a severe miss (don't remember if the SES light came on).

Turned out, the electrode had burned off one plug, and I was running on 5 cylinders. Changing the plugs - which hadn't been done since 100K anyways - solved the problem. But I do suspect that use of the original coils (still in the car, by the way) might have exacerbated the melted plug problem.
