I Have A 98 Honda Prelude Sh. The Engine Check Light Came On I Took It To Auto Zone And The Code Came Out For A Misfire On Cylinder 4. I Did A Self Diagnotic Myself And My Engine Check Flash 1 Long Flash. Do This Stand For 10, A Intake Air Temperature Sensor? Would This Cause Me A Misfire On Cylinder 4? This Is The Only Flash Im Getting. Any Help Is Appreicated.

i would suspect a random misfire to ignition related
check the distirbutor and plugs/plug wires before i do anything else
tell us how it goes

Is it a consistant misfire?

i got new ignition wires and replaced the dist. cap and rotor. i can check again but the check will come on for a long time and goes off but when i check my self diagnotic its only a long flash i dont know whether i should replace intake air temperature sensor?

try the plugs first. that happen to me on my way back to fl but when i got into ga it started acting up. replaced the plugs and it was fine

I'm not sure about your 10 diagnosis. I think it should keep looping/blinking. You sure your jumping the right connector? If it was cyl 4 misire you should get 74

While driving, do you see the check engine light blinking? If so then its misfiring at that moment in time.

run back over to autozone and read the tool w/ the tech. get the DTC and make sure you get all of them if more than 1.

For the heck of it clear the code by pulling out the radio/backup fuse for 10 sec - if you want to forget about the problem. It'll probably come back though.

For misfire the helm manual says to look for:
- fuel injector
- fuel injector circuit
- ignition system
- low compression
- valve clearance
