Slight miss in overdrive

**98-LS1** · 11-20-2006, 06:21 AM

Over the weekend I noticed my camaro started to jerk a little in overdrive while cruising at 55 mph. I can hear it through the exhaust too. Under WOT it pulls hard and driving around normal it runs great, no sign of a miss at all but for some reason with the RPM's low in overdrive around 55 mph it jerks a little and can be heard through the exhaust. I'm thinking it's just the cam loping because the RPM's are low but I could be wrong. Any suggestions on what to look for? I installed new NGK TR55 plugs when I done the cam swap and the MSD wires are only 6 months old. Thanks

Throwing any codes? Probly isnt a miss just A different sound due too the cam. Check your wires too make sure none are messed up but if it doesnt do it all the time then it probly isnt a miss.

I'm going to scan the computer this afternoon to see if it's throwing any, it's definately like a miss though. The car bucks a little and the exhaust note changes, it's hard to explain but it's not smooth. It doesn't do it all the time either which really confuses me, I wonder if the computer is still trying to deal with the cam which is causing the car to do that? It's getting a dyno tune hopefully next weekend if nothing major comes up. Thanks

is it an auto or m6? Sounds like you might just need a tune. What size cam did you go with?

Yeah it's an auto, the cam is a 226/226 585/585 on a 112 LSA. I'm guessing that's what the problem is too, It's showing a random misfire code. Is that common among cam swap cars?

You just need a tune. Do you have it stalled or are you still on the stock verter?

MSD, Taylor, Accell - tried them all over the years. Want plug wires that last and the boots won't mess up your plug insulators? One tiny carbon trail on a plug ceramic can ruin your day.

a few years ago my wifes car had a complete fuel system melt down,they replaced the entire fuel system plus the wires and plugs.Well after that it acted funny just like you discribe.The problem was dirty oily finger prints on the plugs from installing them,cleaned them all and no more trouble.
