Hello! I have a 2001 Mercury Grand marquis with 100K in it. I have a problem that i cant find a solution, i have checked all plugs and coils, replace it, the problem is that when i accelerate the car runs fine but if I accelerate to the bottom of the gas pedal the car doesnt go further and loss power if i accel to the bottom. I have troubleshoot the MAF, i have unplugged the MAF and the CHECK ENGINE light is not coming up when the MAF is disconected, and the TPS sensor is fine i took it to autozone and they test it and works fine, if i unplug the TPS and MAF the car dies, when i unplug TPS check engine light comes on quickly, if i plug the TPS back the car runs fine until some RPMS the car starts to fail but it has a good acceleration while i dont push the gas pedal to the bottom... thanks!
