Alright i am a new member and desperate for some help to my problem. I have 96 accord automatic. Car runs perfectly fine when parked and ideling. As soon as the car warms up and you press the gas, the rpm drops to the point where the car chokes and sometimes it will shut off completely.

The timing belt is new, throttle position sensor is new, i cleaned the idle control valve. I do not have a clue as to what it could be. Any help would be greatly appreciated.

I would have a scanner hooked up to the data port and specifically watch the voltage from the Primary O2 sensor.
I had a customer's car which ran absolutely GREAT when first started; but within 2.5 to 4.0 minutes of running would stop responding to throttle inputs, would run 'flat' and almost backfire out the TB and would require pulling over. The surprising and more than a little aggravating was the fact that after 2 minutes or so - it would clear up and run great until (again) we started up from ambient temps ... and off to the races we would go again.
What was happening was this: As the O2 sensor heated up, it developed an intermittant short between the power feed side to the signal side of the sensor. This (in effect) fed an unusually high voltage back to the computer (which interpreted this as a super-rich condition at the exhaust). Being the Good computer it was, it commander the injectors to lean WAY out - thus the flat spot and no power. As the O2 sensor continued to heat up, the internal short corrected and the sensor operated normally.
The computer didn't set a code because the voltages were present / uninterupted - just out-of-range.
have the Primary O2 sensor checked.
