The car is driving horrible
The car is driving horrible Hey guys, don't post much but a long time reader. I need a little bit of help.
I have a 2002 Z-28 with all boltons(headers, true duals, lid, etc) plus a Torquer v2 cam and all the valvetrain upgrades to go along.
I've had the cam for a year and a half, and it drove great. However, for the the past few months it has been driving really bad. For example, when I drive at a cruise (at any mph) the car bucks and surges really bad, but then all of a sudden it will smooth out. Also, the car backfires at idle randomly, usually when it's warm and i'm at a stoplight. I've replaced the O2's with the Bosch ones, and that didn't help.
It recently got worse when I pulled the intake off to install the new autometer oil pressure sender, if this information helps any.
Any help would be greatly appreciated, thanks.

Borrow a code scanner and see if its throwing any codes (autozone, some oil change places will pull the code for you, done that in a pinch). Did you have it tuned? If you are close to your tuner you may have him plug in and take a look. Sure as hell beats guessing and wasting money on parts that may not resolve the issue

The car is tuned, i'll try to get the codes scanned tommorow. I replaced the gauges with Auto Meter 5" gauges, so I know it is throwing a code like P0650, and I think it's because I had to cut the fuel signal to the PCM. I dunno though, i'll check tommorow on other codes.
I'll also check the IAC sensor, thanks.
