:bulb:Hey. Im new to the forum (post wise) ive read a lot of stuff on here over the last year, never had to post until now . So hello, Anyways. i have an issue with my 78 280z l28 (cold air intake, 2.25 exhaust glasspack muffler) 5 speed (straight gears). It is an arizona car and i need to pass emissions here so i can get my plates and registration. I can get the car to run great under a load and WOT with no miss or studdering. but my issue is idle. It has a rough idle. clearly a miss and rich exhaust. Ive taken it to emissions twice. The first time i took it was bone stock. no cold air intak
