Engine Performance problem
2006 Mercury Mariner 6 cyl Four Wheel Drive Automatic 45000 miles
Sporadic, but willl stall when coming to a stop. Easing into the stop seems to help. Took the car to the dealer, no codes found; and ofcourse it did not stall while the dealer hat it. Ford Hotline suggested checking the grounds under the drivers seat and gas tank. Chose not to do this. Has now stalled twice since.
Did some research, and came across 2 possibilities.
1. Torque converter not unlocking. Would this be an intermittent issue? And how do I check this?
2. IAC motor/valve. I've read that this does not always generate a fault, and can be intermittent.
Could it be anything else?
have the same problem?
