1996 Mustang V6 @ least 134K (It quit counting a few months back.)
A few things, not sure if they are related.
1. My cars temp has been running warmer than normal with the temp gague just jumping all around. I had the thermostat replaced and the system flushed but it continues UNLESS I keep the AC on. The heater core went out last winter and I just bypassed it. AC gets and stays cold, but car will overtheat without it on.
2. Car is running "lean". Not sure what to do first, O2 sensors, fuel pump? Also you can smell gas after you get done driving and I get horrible mileage- estimate 15miles/gal.
3. Just started, when driving it is fine but if in Park the Oil pressure gague goes nuts, Low-High, Low-High, and you can hear the engine reving as this happens. Seems to be getting worse. Car shakes briefly between 40-50 mph and 60-70.
I know I need my serpentine belt changed- does this cause any of this?
This car feels like a money pit, I need to know what to do and in what order to do it, so I can get my only means of transport working to where I feel safe. PLEASE HELP.
