With a car that year, the only replaceable item is the rotor button. The cap itself is also replaceable. If the gear itself gets damaged, you have to replace the whole thing.

1991 mits pk /2.4 truck start but won' stay running

I don't know if this will help you, but I once owned a 1990 model which had a moisture problem with the distributor cap. Everytime I drove in the rain the truck's motor would shut down. Check for moisture or wear in distributor components, especially the cap.

How can I tell what plug wire go where on the distributor cap? Diagram shows #1 but I can not really tell if it is on the left of coil wires or not.

Is this the diagram you are looking at? #1 terminal is behind the screw, right? Does your distributor have the 4 screws? Sorry if I'm not understanding the question.

Where is the belt tenison pully in a 1990 cadilac deville? changing my serpitine belt a i've never worked on a cadillac, just need the location of the tension pullly. thank you

There should be a decal under the hood or on the radiator shroud showing the routing of the belt and naming the components. The tensioner is the pulley that is on a spring that can be moved with a breaker bar or belt adjusting tool. The other components should not be moveable.

I washed my 1990 toyota camrys engine and now it stalls when u drive it but no problem starting

If you steam-cleaned, the vapor seeps into the electrical components and causes problems.

The advice folks hear around the repair shops is: 'Never steam-clean an engine'

If you hosed it down, the stalling may clear up pretty soon.
