2000 cougar starting issues
I have a v6, 2000, with 120,000 miles on her. When the engine is cold, no matter what the outside air temperature is, the car is hard to start. I have to press the gas peddle a little and she starts right up. The fuel pump is brand new, the plugs and wires are new as well. Tested the spark at all the plugs and it is great. She burns no oil, and checked the compression at all cylinders, all pass. Im a little stumped here...I dont know where or what to check next. I dont smell gas anywhere around the car. Any help would be appriciated guys.. Thanks

Maybe a bad or dirty IAC valve.

Re: 2000 cougar starting issues
Symptoms of a Cold hard start could be a dirty, or bad Massive Air Flow (MAF) sensor.
1) Try cleaning the MAF sensor and connector with CRC MAF sensor cleaner. 2) Use a dielectric grease on the electrical connector. It's probably time for new upstream HO2 sensors too! The MAF sensor is a metering device for Air, the H02 sensors are the feedback signals for the ECU/PCU for the proper Air/fuel mix.
