I agree, always best to spend that lil extra and get the quality stuff. I don't think the cap or rotor button is OEM.
Yeah Gerg, I think you are right the ECU seems like its trying to re-adjust/learn and over compensate, its sounding more normal every time I turn it over. when it cools down outside I will disconnect the terminals like you said and start from scratch again. I also picked up Muzzas DTC device this avro, so I would like to run a diagnostic on it too, it may shed some light on the cylinder misfire.
Its more of a boom.boom boom. bup bup, noise I can here out of the muffler, deff a misfire, not like a cross leads/wires sound but more of a Deep lumpy Stage 3 cam, then it almost stall, then rev to 2-3k.
Its interesting you mention the Vacuum leak it was making a loud sucking noise last night when I kicked Monica over,I will also check the PCV. I will try and get some audio and video of it tonight its just too freakin hot out there right now to do anything.
