Bad O2, MAF? The things get old on the Z and are the two closely related to the problem. There are specific ways to clean each so don't guess, look around for the right way if you pursue that.

Not to be depressing but fuel in the pipes can help rusting along too from the inside out, not to mention a fire hazard, be careful

You probably have a nasty miss also. Check and make sure all cylinders are firing. Start the car and pul each coil plug one at a time to find the one that is not hitting. You either have a coil not firing or a bad injector seal. Email me at [email protected] and let me know any info you have and I will help you out.
