i tired the tuning section with no responses so ill try here. i installed a set of longtubes and an ory in the spring of 08. ever since then the car has stumbled and bogged out around 2200 rpms. i had the rear o2 sensors tuned out b ut its throwing a code for a bad 02 sensor, so i figured it was the front ones, i replaced them and it stopped stumbling and then about 100 miles later it started again. i repeated this two more times with no luck. it just fouls out the 02 sensors immediatly. i have a mail order tune from frost, a sponser on here. he said he could send me a speed density tuned pcm and see if that changed anything. i just wanted to see what you guys thought about it. thanks guys

 

Get a real tune. Your mail order tune is probably not cutting it.

 

what do u mean by real tune? dyno tune or street tune or what? got any idea on where i could get that done around milwaukee or southeastern wi since ur from wi too?

There is a place that I heard is decent in West Bend called West Bend Dyno. Otherwise there are many choices in the Chicago area!
