My 93 Accord occasionally loses power when trying to accelerate. the problem begins shortly after starting, and appears intermittently. I can cruise along at the speed I'm going just fine, and then the problem will start and it feels a little rough, especially if I demand a little more power, it runs rough, and won't accel, like its being starved of gas, but getting enough to keep it going. Pushing the throttle further, between 3/4 and full solves the problem and the car gets a boost of power.
The problem soon disappears and comes back 2-10 minutes later. Its been happening for weeks, and I've just noticed the engine light come on once for about a minute. I'm guessing a sensor is malfunctioning, is there a way to diagnose this? the car has 260 k km,
