Hi everyone, I've recently noticed alittle problem with my 99 lude where when I reach higher rpms (roughly 7200 or so) my car backfires slightly (stutters and hear alittle popping sound..). This usually happens in 2nd and 3rd gear. My car has aem intake and catback exhaust. I've also reset the ecu with no luck

Any help would be greatly appreciated

Definitely not normal

Have you cheked the obvious things yet? Plugs, cap & rotor, wires? What about a bad tank of gas? How many miles do you have?

Mine did that when the plugs had fouled from using octane booster.

New plugs, problem solved.

I also quite the snake oil.

It could definitely be that you got a bad batch of gasoline. With this goofy weather in the north (cold, then hot, then cold again), the gasoline suppliers are vacilating between using the winter stuff (it's got all kinds of goofy additives and whatnot) and the summer stuff. Check the condition of the plugs, too.

I guess I'm not really adding anything to this conversation, just restating stuff.

About the gas thing, I've noticed though that a lot of Lude owners in cold weather climtates have experienced rougher idles and weird stuff going that coincide with the changes in temp. I've been told by my mechanic that it could possibly be related to the gas used. SO take that for what you will.

Thanks for the suggestions. My car has 33000km so it's fairly low mileage. I fill up with 94octane gas and I've filled it up a few times already with this 'backfiring' appearing once in a while. Plus I haven't checked the obvious things (sparkplugs, etc..) since I didn't think they were bad with the low mileage and no weird idling or anything at all! I did install my dc sports exhaust at the end of winter and not sure if that screwed my a sensor or something...
