Recently my car has been running good however at 3,000 rpm it sputters really bad, if I tap the throttle it will break through the 3,000 rpm sputter and then pull nice the rest of the way. Ive tried everything from VPC's, Plugs, Igniter's, ECU's, etc.. Another thing I noticed when I hook up with a snap on scanner or try to pull codes the ECU does no respond and the check engine light will not come on at all, even when I Initially turn the ignition I get no check engine light. Im trying to make Texas 2K2 so any help would be appriciated.

Thanks
