95 cobra 5.0, runs fine sometimes when cold, as soon as it warm up flatlines at 3000rpm. acts like there is a rev limiter, and also back fires. changed o2 sensors, battery, plugs, wires, cap, rotor button, pcv,fuel filter.vacume tested egr, tested maf.no help. thinking fuel injectors, ran tank dry once before this happened, gas ran brown out of fuel filter. think this is what it is but wouldlike any help anyone one may have


thank you
