i have a 86 rx7 bought it about 2 year ago and blew the motor racing at C06 bett i bought a new motor but ever scinse my car wont pass emission it runs to rich. i already replaces mass air flow sensor and tps and also new injectors from napa but it stills runs rich. at first i could not get the car to idle and fixed the problem but now it wont go past 4,000 rpm if you try to drive it but if its at idle and hit the gas it revs perfect
