I'm having a problem with the the check engine light post mods recently installed. I installed a cat delete mid pipe, SAS removal, canister removal, O2 dongles with a PCV. It's not throwing any major error codes on the screen just the engine light is on and all the appropriate dongles were installed. It runs like great and pulls even harder but I'm wondering if anyone had an idea what might be causing the issue before bringing it into the stealership to get hooked up to their code machine. Thanks in advance!
