Three things come to mind.

First is it a rough idle at normal rpm level which could indicate the throttle body needs cleaning.

Second is you have a faulty Idle Air Control valve (IAC)'

Third is you have clogged or dripping injectors. Injectors should have a smooth cylindrical spray pattern.

Most likely it is a transmission problem. Being that old the transmission needs work and possibly the clutch replaced or Throw-out bearing.

My 94 topaz stalls out when i'm ideling?? Has anybody had this problem before or any suggestions???


DO THE FOLLOWING
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
