trex cam swap issue So i got my computer back from frost and put it in and seemed to start up better then I drove it down the road and it bucked and miss fired pretty bad and wouldn't want to idle at all after letting off the gas and the higher the rpm I went and let the rpm drop to idle it would either stall or drop to like 100rpm until I gave it some throttle to bump it back up. I got back put all new plugs and wires in started back up car ran great until I drove it longer and the same issues started up again. Only one code was set off and it was a bank 1 sensor 1 code, I pulled the plugs again and they we re black again. I checked the maf and it's fine also. Hope to hear back from you soon so hopefully we can figure out what's going on thanks Cory.dum

it is your 02 sensor in the exhaust. Which ever side of the motor had black plugs is the one that's bad. You said bank one. That should be the driver side. Mine did it shortly after Frost dyno tuned mine. I don't know if he adjusts sensitivity or what. New o2 sensor and you will be good to go. Clean the plugs ad put them back in. Mine will start sputtering and running rough well before I get a check engine light. First thing I do is like you check the plugs. If two on the same bank are black I go exchange my o2 sensor. I use autozone because of the warranty. If you have log tubes get an o2 sensor for a corvette.

It's on stock injectors still, but all the plugs were black just the one code popped up but that was after a few miles of it running like crap, so new corvette o2's would fix this problem because of the switch rate is faster? I had my scan tool on it to watch the o2's and they looked like they weren't reading very well also they are black to.

glad it's running better. What do you think of the trex.
