Over the weekend, I tore the heads off of my 02' 4.7 because I was getting coolant on 2 of the cylinders. Well long story short, everything went back as planned after replacing one head and doing a valve job on the other. The only problem is that since, it has stalled on me four times. It's more like when I turn the wheel all the way one way and once when I put it in park. It felt like the idle was lower than normal when putting in park. Now I did clean the TB while off, maybe thinking I messed up the iac when I had it off and cleaned it. Any other thoughts? Other than that it runs like a new truck.

 

Any codes?

 

Try disconnecting the battery to reset the truck.

No codes in the ecu. I did try disconnecting the batteries again. It has not killed on me again since my initial post. My idle is fluctuating some, from 600 to 1000 but then settles at around 600. Thinking I'll change the iac and tps when I get a chance.
