1994 Misses/Backfires
Okay, to start out I have a 1994 Grand Marquis with 115k that misses/backfires
At 100k it had a slight miss when cold so I replaced the plugs/wires with generic autozone set (the miss was a little better)
At about 112k I replaced the MAF sensor and the car ran beautifully for about 2 months and now runs horribly, I have already tried another MAF sensor and that is not the problem
I have also replaced the air filter, thermostat, and the DPFE sensor (and here is where it gets weird) My car had a December of 1993 build date and I had to use the DPFE sensor from a 1993 since the 1994 was totally different from the one on my car
This car misses/sputters/backfires/chugs whenever I put it under load, rather I am accelerating from a stop or accelerating to pass and it doesn't matter if it's warm, cold, hot, lukewarm, whatever
I am at my wits end, my gas mileage is now terrible and I am afraid to pull into traffic with all of the hesitation/sputtering misfiring....PLEASE HELP! I am at my wits end
