My 2000 Mercury Cougar has let me down. Today the car kept getting weak on me, trying to die at stop lights. It was running just fine until yesterday when I put some gas in. I normally run 89 at BP gas station (this is recommended), but it will not run properly with 89 so I use 91 and it runs good, but this time it caused weakness in the idle.
This morning when I started the car to go to work, the car was very weak idling. Twice the car died on me today. I asked Autozone what could be the problem. They advised me to try "Heet". I also spoke to a mechanic who stated that the problem could be bad gas, catalytic converter, or MAF Sensor. This is the first time the car has ever done this - can anyone tell me WHAT IS GOING ON??
Come on! The car has 170000 miles on it and rough idle is the only complaint you have?
Give it a tune up and quit complaining.
