Been working on this issue for months maybe even years now, it’s the same thing every test drive, it runs perfectly except for size varying hiccups and/or hesitations up at around 2k rpm, the code we’ve been receiving all this time has been code 212: loss of IDM (ignition diagnostic monitor)...
Having a slight problem, new to mustangs and just got a 93 foxbody (5 speed) a few days ago. It Sat for a while, not sure how long. Anyway, it runs really rough. During idle it isn’t too terrible, sometimes it might vibrate. But the real problem is when I try to drive it. The car has no power...
