Q: Acceleration failure on 1990 Honda Accord

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have a 1990 Honda Accord Ex with 262,000 miles. When the engine gets hot, the car tends to have acceleration failure. Pressing the gas pedal decelerate the car and it will not normalize itself until I stop and start driving again. In addition, after long periods of driving the car shuts-off when slowing down to make a right turn. Any idea what the problem (s) could be? My final issue is "S" light that sometimes appears and stays steady without flashing codes. When this happens, the car does not shift automatically unless I disconnect the negative battery connector for 10 seconds and reconnects it. I recently replaced the TCM and it works great for a while until this happens. By the way, this is my third replacement. Once the "S" light is off the car shifts like a baby. Any advise would be appreciated.

This is going to require a diagnosis by a qualified mechanic. Replacing parts without a proper diagnosis is not only costly but you increase the chances of having more problems.
If you don't want to take it to a shop, then get a good repair manual and learn how the systems operate and then try to diagnose the problems.
That is the best advice I have.
