Chances your check valve and air pump are bad from too much mosture in the pump. Happens from check valve not closing and allowing moisture from the exhaust to gather in the pump and rusting it. First check the motor by hot wiring as suggested by fcp. Just installed a check valve today from those fo...

Great picture! I did one in the more conventional way but do not know if I would do another. Any way, still no leaks 3 years out.
Replaced all seals in the transmission also.

If your car overheated you most likely have a broken thermostat. The thermostat is designed to purposely break (one leg) in order to pass more coolant.

Check the RWD FAQ on brickboard.com They have many good suggetions. Also, the brain in these cars can give problems with starting and I have had to replace one or two.

If this is a 4 cyl single OHC engine you have solid lifters. The double OHC engine and V 6 have hydraulic lifters. If it is the 4 SOHC the clicking may be from the little hushers being worn out. These can be replaced quite easily without taking the head off.

Check your vacuum valves at the intake manifuld. There are two sources there and a leak can mess up all the happenings. Also, there is a valve und...
