1992 Honda prelude problem

[roy_lude]

hiya, i have a 2.2vtec 4th generation prelude. The engine management light is now coming on after 5mins of starting from cold & then starts mis-firing & generally running really rough with a lot less power. I think it could be a temperature sensor somewhere but not to sure. could anyone give me advise on what could be causing this problem or what best to check 1st? thanks.

i managed to get the code...which was cel 9 which, i believe is the cylinder/crank sensors which are located in the distributer. i recently had the distributer replaced so iv taken it back to the garage...so im just going to have to wait & see what they say. its just a pain in the arse really. I think they've given me a faulty distributer. if they say that the distributer was fine, is there anything else that could be wrong with the car that is causing the distributer to become faulty? thanks

well, sods law....the garage came back & said there was not a problem with the distributer. the cel is still on & car is still running rough & mis-firing. could anybody help me in what to check now?

thanks
