I'd like to clean my iac if we have them on our trucks but I've read that we have the electronic monitor that's connected to the something on the throttle boy. Do we have the them on the 5.4 3v cause I've cleaned the TB and MAF. My truck is stalling when coming to a stop or slowly accelerating from a stop and D like to figure out whatnot is and fix it

And where the heck is the pcv valve

Not on the 5.4 3 valve. Have you changed O2 sensors (just the upstream) lately and when was the last fuel filter change done? Have you inspected the brake booster hose?

Did you take the TB off and clean it, or leave it on?

I haven't changed the 02 sensors, the fuel filter was changed when I changed the oil 1 1/2 weeks ago and yes I took the TB off to clean it thoroughly

I havnt inspected the brake booster hose and what am I looking for ?

The PCV valve is built into the underside of the valve covers, and no IAC- not needed with the electronic throttle body. You can also check your TPS with a voltmeter, see where your idle voltage is.

Look for the brake booster to be collapsed or have a split. O2 sensors are good for about 75K miles. Just the 2 closest to the exhaust manifold need changed, the other 2 monitor but do not adjust anything.
