Hey guys I'm new but at my wits end. I got a new (to me) xj it's an 89 and it idles fine but back fires and pops like crazy at any Ron over 1k. It has an after market onboard system and everything's looks to be reading ok except it's rich at idle. Enters closed loop sometimes sometimes it stays in open loop. The guy I bought it from have up on it after replacing what looks like ever sensor on it. TPS, CPS, MAP, MAT, 02, and Coolant temp. So if no one has had a fix for this I can include the numbers from the onboard system. Or anyone knows a shop or person around Sacramento I'd just like to get this thing running before spring. Thx guys
