Hey all. I am new here and I have been having an intermittent misfire problem with my 95 GT. So far I have had quite a bit of work done to my car this year, about $5000 worth. This problem started about 2 weeks after I replaced the fuel pump in July. When it happened my code reader gave me the code for the Air Temp Sensor so I replaced it and the car ran fine for a week then it started happening again. I am now getting a code 311 and 314 which is the Thermactic Air System. The smog pump was removed by the last owner and I have been over all the vacuum lines and ensured all have been plugged, no leaks. I drive about 20 miles to work and in the morning with no problems. I make it home from work with no problems but if I go anywhere else it starts acting up. The car chokes down and is flooding out. If I can get the rpm's up it runs smooth for a few seconds then you can hear the misfire for a second or two then smooths out, then misfires, smooths out and so on. At low rpm's it chokes down and dies. It is acting like something electrical is heating up and causing this. I have replaced the coil with a StreetFire, the Ignition Control module and the Relay Control module. I replaced the fuel strainer and fuel filter when I replaced the pump and also again in October. I have also replaced the plugs and wires since this started. The distributor was replaced in April with a stock replacement but I want to go with a MSD StreetFire soon. The cap and button were also replaced with a MSD. Any ideas? This is driving me crazy! Any and all help is greatly appreciated.
