It started after a weekend of traveling and 1/4 mile racing in Bristol. I had a small backfire between shifts. I was a little paranoid because I missed a gear (just didn't make it into third) and I bounced off the revlimiter hard many times.

Then today I had a bad stumble at 5500 - 6200 rpms. There was a considerable power loss and a light poping sound from the exhaust.

I had already ordered 8 pushrods because I had planned to pull them and check them. However, I remember several people from old days past, CrkHeadMatt stands out the most, that their plug wires were bad. So I got a box of Accell plug wires too.

I replaced the plug wires and now my car pulls stronger than before. I was running Magnecore wires (with about 15,000 miles on them, but not anymore.

While pulling them out, we pulled off three of the ends. <img src="images/icons/shocked.gif" border="0">

Lesson here? You might not have bent pushrods so check your plug wires before you get all excited. Check the simple stuff first.

Just a friendly reminder.

Yep, that's a good reminder....bad plugs or wires can cause a lot of headaches before you figure it out.

Thanks for the advice Eric! I had a similar thing happen to my 98 Formula, one day all of a sudden it just got this real bad high rpm stumble, so bad that I thought the fuel pump was toast. Before I was going to take it to the dealer though, I figured I'd try changing the plugs, even though a quick pull of one of them appeared as if they were ok. But I still changed them anyways, they were TR6s with 13k on them, and apparently even though they appeared fine, they were toasted, since when I changed them the hesitation totally disappeared.

So it's often the little things that can cause problems that seem like they might be bigger.

I've done the same thing for my 99 Camaro and my problem is still there.

I would test everything, plugs, wires, & coils.

7 year old thread revival, holy crap! Don't forget other simple things such as fuel filters and clogged injectors too. Good luck!
