1992 Dodge Shadow stalling in reverse and down shifts when

The Check Engine light means the Engine Computer has detected a problem and stored a diagnostic fault code in memory. Have your mechanic read the code(s). That will indicate the circuit or system with the problem, not necessarily the defective part.

If you want to try to read the codes yourself, it is by far the easiest to do on Chrysler products. All that's required is to cycle the ignition switch between "off" and "run" three times in five seconds, then leave it in "run" without ever cranking the engine. Then you count the flashes of the Check Engine light. It will flash two-digit codes as a series of flashes with a short pause between the first and second digit, and a longer pause between each code. If you can get those codes, post them in your reply.

Don't waste your money on a fuel filter. Other than on diesel trucks, they will never solve a running problem on a Chrysler product. The largest volume of fuel goes through the filter during coasting. Most of that fuel goes through the pressure regulator and right back into the tank. Only a tiny taste is syphoned off to go through the injectors into the engine.

Even though the Check Engine light went off, the codes are still in memory. They should be read soon though because if the problem doesn't come back, the computer will automatically erase them after 50 engine starts. That's one to two weeks for most people. Once they're erased, that valuable diagnostic inormation will be lost.
