Anybody else noticed this with the '11-'12 5.0? Get out of the car, run into the store, bank, etc....come back a few minutes later and start the car, put it in reverse or first gear, begin to give gas and let out the clutch and the engine hesitates like it's going to die. This only happens when the engine is warm and has been shut off for only a short period of time, and it only occurs right after start up, it goes away after 15-30 seconds.

I have a 2011 California Special with the 5.0 engine, automatic. When I start the car in the mornings when the engine is cold, there is a hesitation when I put the car in reverse. I also have felt a hesitiation when I start from a dead stop for the first few minutes of operation when the engine is cold. Then everything is fine for the rest of the day....no hesitations. When I say cold, this is during the summer in Florida and the outside temp is 80 degrees or higher in the mornings. Anyone else have the same problem or a clue to the issue. Thanks

There is a thread on the site somewhere talking about some guys with 2011's getting an upgraded tune from Ford. I'm not sure the thread title or the reason they were eligible for the tune but those who had thier cars retuned said it made a big difference. Better throttle response, seemed to make more power etc....

Might be worth looking in to.

I've never experienced any of the issues from post #1 or #2.

as far as starting from a cold start do you sit and wait for the rpms to drop back down to 1k rpm? because the car revs up a bit for awhile, gets the oil and everything flowing from a cold start.

The problem happens after the engine revs up and returns to normal RPM. When I leave the driveway and drive down the street it occurs when I slow down or stop at a stop sign. The hesitation goes away after a mile or so.

I have the 2011 5.0 myself and i have the 6 speed manual, and I've never seemed to notice any hesitance from it

It is natural for the Coyote to want to hesitate while cold, especially at low RPMs. DD RPMs are form anywhere between 1500 RPm to about 2500 RPM, 3000 if you are more lead footed. Of course, 1500 RPM is granny driving.

At below 1750 RPM, the coyote does not like to bear alot of load, so it tends to not like having the clutched released onto it so quickly at below 1750 especially when cold. I find I have to ride the clutch and slip it a bit and not let it fully engage until above that 1750 RPM mark to prevent hesitation.
