I started out with a code 36 and ended up with a 33. New intake gaskets, EGR valve, blocked off injector, checked the TPS adjustment (.67), Cleaned throttle body, new IAC and now it throws a code 33. New plugs, wires, cap rotor, Anybody gone thru this road before? Advise needed badly. Before I replace ECM I want to be sure. MAF is clean and replaced relays. Its startin to piss me off!

That looks like a good article. Others have had problems with those codes from poor connections. I'd check those first. Do you have a FSM for the step by step diagnosis?
