Figured a GEMS was the one and dropped on in, hoping it would work. Upper Callaway plenem and air flow sensor swapped from original engine. It does run and idles fine but at around 2k RPM it misfires. I have been studying the Gems manual posted here. Wonderful data! Thanks!Codes curently come up with is " misfire catalyst damage fault bank a" and before that: "misfire excessive emissins fault". To remedy so far I have: gasketed plenum and upper intake, cleaned MAF, new plugs (champion), new wires, fuel pressure sensor, checked compression and coils. Next to me would be to suspect Cats and MAF though no other codes are reading. Does the first code mean catalyst damage is causing the misfire or the other way around? Can I solve this with my standard code reader? Is there anyone near me (central ohio) willing to lend a hand? I have just found my battery is bad and won't hold a charge too. Thanks for any help.

Did you put a long block 4.6 from a non callaway in there, or di dyou reuse the heads?
In other words, what parts did you use that DIDNT come with your Callaway?
