I've bought my fiance this car from a friend of mine. I put an engine in it out of a 2000 model camaro. I swapped the intake and throttle body to the 97 style. I had codes for the TPS and MAF so I replaced both sensors. The engine still idles at around 25 -2700 rpms. I now have 0 codes. what could be the cause?

IAC valve can be faulty. Or vacuum leak, generally intake manifold leak.
