I have a 2009 F150 4x4. The A/C cools fine when driving. However when it is at idle it stops cooling and the engine lurches. Any ideas?

I took my car in to the shop and they found there was a lower intake manifold gasket leak. They replaced my upper and lower manifold gaskets and now it runs great! We have been going through a process of elimination and started with plugs and fuel filter, then battery, then cleaned the fuel injectors and finally the intake manifold gaskets. Replacing them seems to have done the trick.

You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.

There is a problem with the thermostat gaskets. Often times they leak and allow cars to overheat. Check under your car and make sure that there is no coolant leaking. MINI has updated the gasket so if you get your car serviced at a mini dealer then your gasket will be updated. There is not a bulletin or recall for this replacement this would be at your cost.

hello there:
you may have a blockage in the system and then again it could also be low on freon and may just need to recharge and i would suggest taking it to an a/c repair shop and have them do a diagnosis on the a/c system it should not be more than about $150 for them to check system and recharge the system unless you have other problems hope this helps you out please leave a review thanks sincerely D.Jones
