OK, you did not mention what type of fuel injection system you have. I am assuming you have a model 220 TBI unit.
I believe your problem is actually the "fuel pressure regulator".
The replacement part is actually called the FUEL METER COVER, with pressure regulator attached.
It is sold mostly through the dealership parts dept. But check the local parts guys for prices.
It is a simple 20 minute change over but you need a #15 torx screwdriver and Locktite 242 or 262 for all the screws when assembling.
You have been flushing or cleaning the fuel sytem. That stuff can actually make the problem worse when a problem starts. Build up inside is now loose, seals are weak allowing improper air/fuel mixture causing major confusion with you computor.
Do you smell raw gas? Is it hard to start after its been running? Fuel gage working?
Do you have the proper fuel pressure from the tank to the injection system? (Requires a special tool, mechanics have them) A quick check for this is to take off air cleaner, start engine, lift the alluminum ring arounf the tbi to see the flow of gas from the injectors. Should be constant even flow. Actuate the throttle by hand, flow should progress to a spray.
When release do you have an erractic idle? If yes, replace cover.
Very important note, before replacing the cover unhook the battery to prevent any spark, clean the gasket surfaces (2) with a lint free rag and the excess gas that will spill out. Let air dry and assemble.
If you have a transmission problem, you as the home mechanic cannot fix it. Call around to tranny shops and get a quote to scan your trans. You want a printout and no obligations. Do not let them drain it. You just want to see what the scan says first. If there is a problem, then you can shop that around for the best price to repair. This scan service may cost a few bucks. Ask first how much. To me this does not sound like your problem.
Let us know what happens or if you require more help.
PS, I know this because I did the same as you by replacing every single part and then the engine.
Everything new except the TBI fuel pressure regulator. Wasted a lot of money to get good spare parts. If you have flow out of the injectors, they are ok. In the future the only thing you should put into your tank is a good quality gasoline, 87 octane. Discount gas is usually 85 octane. Gas additives are bad for your engine over long periods of continued use. The age of yours, you should not need it.
