Re: 95 B2300 Mazda - Wont go above 3000 RPM
Fuel pressure test, and then replace the IAC and TPS. They should help, if not solve the problem. A shop can better diagnose the possibility of having faulty intake gaskets.
IAC - idle air controller
TPS - throttle position sensor; can vary rpms at speed without cause
