Re: 90 rx7 stutters at half to wide open

the rex has a series 5 motor that has a set of butter fly valves that might be sticking check the diaframs and make sure that they are opening.
also dont pinch the fuel because it can cause fuel starvation and eat your seals.
also check your fuel injectors for resistance it should be between 4-5 ohms.
let us know how it go's
