Thread: 93 GTP with DOHC 3.4L

Few things I would check with the overheating would be coolant lvls/condition. Check for air in the system and if all that looks ok replace the thermostat. Check for vacuum leaks, plugs and wires for the rough idle. In my 93 I had a horrible Idle and it turned out to be a vacum line that I had knocked loose while servicing. But if this is a new purchase deffinatly check your plugs and wires.

Haha funny you should mention vacuum lines, the previous owner said he replaced a few, perhaps he messed something up? I'll try the coolant flush, using the bleeders, and I'll look up the procedure in Mitchell when I'm at work next time so I get the bleeding procedure right... apparently it's quite the process. Any ideas about the oil leak...? It seems to be coming from the rear of the motor... valve cover maybe?? And the idle is so much rough, it just fluctuates and sort of bogs I guess would be the term, typically when rolling to a stop, around 20-15 km/hr downward, seems worse under heavy braking, nearly stalls, most of the time when sitting still it's when the fan cuts in, which is worrying :S
