1998 honda prelude check engine light goes on if i quickly rev the engine to 6000 rpms

Hi there. There could be a number of problems here, the three focus points should be a faulty MAP (Manifold Absolute Pressure) sensor or there might be a problem with VTEC if that's fitted on your particular engine and the other is the Crank Angle Sensor. Firstly, you need to check out the PGM-FI ECU and see what LEDs flashing, this will certainly help narrow down the problem. As a visual check, make sure all the vacuum pipe connections are in-place and there are no broken, cracked or loose vacuum pipes, especially to the MAP sensor. Failing that, you might need the help of the Honda Dealer - but that's what I'd be looking at firstly. Best regards. Scottech

Your o2 sensor is not reading right change it out and it will be fine

If it runs good no worries. Your check engine light will turn on if theres a problem in one of your sensor, reving it on hi rpm will normally give you a light..
