Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
i have a 92 prelude with a 2.3 dohc engine. It has 190000 miles on it. My problem started with when i had to slow down fast or come to all most a stop. When i began to give the car more gas it has no power and acts as if it wants to die. I then would feather the gas and it would pick back up, and run fine. This only happen off and on for a couple of weeks. Yesterday this happened again but now there is a miss in the engine and now it has less power and feels as if it has a slight miss when running at speed. It runs a little better once the engine warms up good. I have changed the plugs, plug wires and fuel filter. None of this helped. I can't get a diagnostic test done for a few days. Thanks for any help.

Did old fuel filter have any water or trash in it?
Old filter is a good place to ckeck fuel. That quick stop COULD have sent
water to trough fuel system.Just a thought. I say its fuel related,may try injector cleaner.
While I agree that it could be fuel related, there remains the possibility that it is an air flow issue. Due to age and mileage, it could be a fouled and failing catalytic converter. Does your vechicle have a tendency to stutter when sitting at a light, or under hard acceleration it loses power or losing power while traveling up a grade? Check tailpipe for very hot exhaust or intermittent flow.
