Question about 1994 Geo Prizm
Washed the engine now the engine runs rough wont stay on . Replaced cap , rotor , & coil still runs rough .
SOURCE: 1991 geo storm stalling at idle
maybe try replaceing the ingnition modual. that part can do a lot of weird things to these cars. its located inside the distributor cap, really easy to do. about $40 and 10 mins or less. sometimes as they start to fail they do odd things sometimes but not always

You will need to have a service manual.
Basically what you need to do is make sure the number one cylinder is at top dead center on the compression stroke and the valves for the number one cylinder are both closed. You will need to have the timing sprocket at the cam shaft exposed. It will have timing marks which need to be aligned. This is where the manual will come in handy.
Be very careful in moving the crankshaft with the timing belt removed or mis-adjusted. Very very very few engines have clearance between the valves and pistons. If you use the starter to move the crankshaft with the timing sufficiently off, you will bend / break either a valve or piston.
Best of luck, Jim
