Yes, I purchased my vehicle in july of 2017. When I test drove the vehicle, everything seemed perfectly fine. Yet, the day I received it, I went to the gas station to fill up. Upon returning home, 1 mile., the engine light came on. I was told by the seller all was perfectly fine. Drive the car, it will be fine. I was concerned and I took the vehicle to my mechanic. After running some diagnostic tests, I was told I needed a catalyic converter, repairs over $1500.00. I was reading the recalls for this vehicle and came across campaign id# the federal safety agency 04v421000. The recall was for contamination of the filter I the fuel delivery mode(fdm) can reduce and eventually block, the flow of fuel to the engine. In which, can cause many problems. I have those problems with the vehicle. Upon starting, it revives up, then eventually slows down and almost kills. It sounds as if no gas is getting to the engine. Loss of power, stalling. My question is how I could find out if this recall was done to the vehicle. Where do I start. I realize its been more than 10years from the purchase of it new, and I didn't purchase new, but if the recall wasn't done...may I be entitled? The vehicle only has 68,000 miles on the engine. Is this the problem and has it now effected the catalyic converter? Thanks greatly for your precious time. A reply would greatly be appreciated.

Would not start in neutral or park, man pushed it into the ctr. Lane out of traffic area. Policeman came after I called 911, after a few minutes he suggested taking key out stepping on brake then inserting key back in ignition, did that and it started right up, and he followed me to my st. And I got safely home. Prior to this shut down incident it had stalled going down a hill however put it in neutral and it started up again. This incident could have caused a serious accident, prior to this incident it had been cutting out for a couple of months which I thought was cheap gas, so changed to tectron.

Since purchasing 2002 mercury cougar in january 2010 the vehicle hesitates, surges, and stalls at any rate of speed. Initially the problem was rare, then gradually occurred more frequently. This now happens at least weekly, sometimes several times per day. This issue has endangered me more times than I can currently recall. Replaced alternator, battery, egr valve and sensor, iac valve, and catalytic converter. The issue persists.
