OK, need the experts here. 2 days ago I put gas in the Thunderbird and drove it around, the next day the car started fine, but as soon I left the house and went from 1st, 2nd, 3rd, the car lost power and stalled. tried to start it and no luck, can hear the pump but nothing, after 10 min sitting, I tried and the car started, but it develop a very loud hesitation (like an old engine sound) drove it to my friends house 2.5Miles away and everytime I accelerate it will lack of power (like driving and you press the brake hard, no power either) and some fuel smell coming from where the fuel filter is (2 weeks ago I replaced it), after checking all wires, replacing the fuel filter again, the fuel pressure regulator, the DIS, the ignition coil, the Map and MAF sensor, the cam position sensor, O2 sensors, put some seam foam in the gas (thought it may be bad gas), still have the hesitation and sounds like a old car but very little now when I drive and specially when I accelerate(you have to sit inside to hear it) but the engine shaking still there ( is not that crazy shaking but noticeable). I disconnected the IAC and the TPS while running and there was not changes in the engine idle, also the MAP(the one by the air filter) and the MAF and no changes. NO CEL at all. today I change the spark plugs, they were fine. I also replace the IRCM and nothing. The car has full power again and drives, sometimes when the RPM drops, it sometimes drops too low below 400rpm but it goes back up. the car starts right away. I have to change my power steering pump because is acting up, but that is been a long time issue. I put fresh gas now and no difference. I looked at the engine mount and tranny and they seen good, the oil pan is not sitting on the frame. also I plugged to a code reader and code 543 came on but like I said no cel at all. so I do not know what is going on!!!!
