Hey guys, I have an issue. I have searched all the forums very thoroughly and have found nothing. My car seems to be in a limp mode. No matter what gear I'm in my car will not go past 5k rpm. It loses all power and just drops off. It will even give a little pop like a backfire when it hits 5k. Could it be my timing is off? My initial thought was fuel or spark. So I replaced my fuel pump, fuel filter, spark plugs and wires, dizzy cap and rotor and still the issue is there. I was told that it could be from having the wrong ecu, but I don't know if the previous owner did anything with it. I would love any help I can get. Thanks, Robert.
