nope...the afc is not the prob. it is most likely something to do with the oil leak. is there any oil in your antifreez? just check the overflow tank. a leaky head gasket is one of the possible problems.
you might also have a clogged injector. try using injector cleaner in a tank and see if it helps any. injectors and an afc would help, however i don't think that this is the problem.
what setup exactly are you running? what engine?
i think the gasket didn't seal properly when it was put back together. where's the oil coming from? is it from between the head and the block?
if it's coming from there than it's definitely that the head is not sealed properly to the block.

btw, billscivic00---i highly recommend the new greddy 19t turbo kit. with the kit and intercooler add-on you'd have quite a bit more power than with a jackson charger, and have TONS of room to upgrade later on. i have the older greddy kit on my 1997 ex and i'm told that the new turbo is better and can go up to 300whp. it's also very tried and true, from personal experience.
