I have no engine codes showing. My car idles perfectly, when I give it some gas it will start cutting out at 1800-2000rpm and I can smell unburnt gas in the exhaust, I can rev it past 2000 rpm but it misses and pops horribly. I have checked the catalytic converters, I'm positive they are fine, I have checked the resistance in all the wires to all the engine sensorsand they are all good. I've put new plugs, a new maf, changed the fuel pump checked to make sure the throttle body is working, and put in a new temp sensor. I also checked to make sure the timing hadnt slipped and its fine. I checked the ohms on the crank sensor and it read fine. I had the fuel injectors taken out and cleaned and they are fine. What do I check next since I don't have any codes I don't know what to check next.

Is the reduced performance light on?
