Ok, I have a 1998 honda passport which is a rodeo with honda badges. 3.2l, rwd, automatic. I have a Misfire in cylinder #3 which is intermittent. It usually starts when the engine reaches normal operating temperature, and is very random. It will start and miss for 30 seconds, then will run normal for 20 seconds, but the length of time is random and will continue as long as the engine is running. It stops missing at higher RPMs. I changed the ECM, the coil packs, and spark plugs. I have no other idea, any help is much appreciated. Thanks.
