I keep having this code pop up. I've changed plugs and wires. When I restore the stock tune it'll run perfect for about an hour then it'll misfire again. If I reinstall the performance tune from the predator, I usually have similair results. It'll run fine for a while then start misfiring again. Any ideas on what could be causing this??????????????????

well have you logged which cylinders are misfiring? that might give some insight. ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
log the current or history and you should see if its a bad plug/wire/coilpack.
if they are all misfiring ALOT, well, maybe someone snuck a cam in there overnight

With the hotcam I get that code if it idles after about 4 minutes or so, but it comes and goes.

I bought the car new. It has the stock cam. It's random multiple misfires. This is what really has me puzzled. I guess it's time for me to shell out the clams and take this bitch to a tuner..........I guess I need to hurry up and buy a cam too so I don't have to pay for two dynotunes. hehehehehehe

i've heard of an unbalanced 'verter causing misfires? Do a search on the topic.
Where are you logging these? every car will log misfires to a degree but without a cam you shouldn't be misifiring unless your tune is way off.

Just for the hell of it, I pulled off the MAF yesterday and cleaned it with alcohol using a Q tip. I've put about 40 miles so far without a misfire. Maybe that solved it. I sure hope it did because I'm tired of this crap.
