Hello all, I'm a new member here so please bear with me.. I just purchased my 92 Prelude.. it has an H22A installed in it, with the proper wiring for the VTEC, howe3ver it camne with a P14 ECU.. so I was told to get a P13 for the VTEC to work.. I get the p13 ECU, put it in, and the car idels STRANGE.. idles really low.. then goes up to 2000rpm.. then down to 1000rpm in 2 second intervals... Is there anything else that I have to be away of when I do the ECU swap? OR what could possibly be causinng this? Thanks!
