Question about 2007 Ford F-150 Harley Davidson
2007 F150, 5.4L 3v, I have a misfire at low RPM when cold or when in traffic. No codes have come up. Would a bad variable valve timing solenoid cause the symptoms?

It's common that you get a lot of carbon build up at the base of the throttle body. Give it a good spray cleaning with injector cleaner and dry it with a hair dryer. If you find it still to dirty, you can try it again with a second can or if you can try using Sea Foam that you can buy at an auto parts store like Auto Zone. The Sea foam will clean out the carbon but also create a lot of smoke.
When i say lot's of smoke, just do a search on You Tube for Sea Foam. Good luck and hope this helps.

Valve is between accumulator and evaporator on the passenger side. Your van originally came with R-12 freon, so you will need to verify that it has been converted to R-134 before adding freon. The different gasses (and especially the lubricating oils) do not mix well.

just pull the pan and it's the solenoid next to the linkage it's a round canister with two 90degree prongs when you get done pull the pos battery cable this should reset the computer and take care of any codes.

There are few possibilities that can cause engine misfire
issues. It can be issue with spark plugs or faulty spark plugs. Also get the
compression test done for cylinders. If any of cylinder shows low compression
then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.
