I'm thinking that you and the other guy that reported this may just have a
problem with your PCM or soething. Now I don't race my truck at the track, but
I run her pretty hard on the street out here in Phoenix. I blew away some
farthead in a little terd coupe' a couple weeks ago at the end of my drive
home. It was 114 with humidity that day. I was runnin the a/c the whole time
and the temp guage was sitting at about 210 for several days since it was so
hot. I havn't experienced that problem that you reported Matt. Our trucks are
pretty similar except mines a 4x4 cc. But drive trains are alot alike engine
and tranny wise. Just an fyi... I may be full o' dyno droppings....
Hey, for the insulation for you pcm why not roll your local Dominos Pizza
Delivery boy and steal his Heat Wave bag!! You could wrap that around your
pcm!!!

Thats true, It should be designed for a hot environment, but apparently it
has a sensor that is detecting a predetermined temp and making the computer
shut off fuel/spark supply. Only happens in hot conditions, and is
activated by clutch engagement after WOT. Not sure about the surface temp,
varies depending on conditions, but I know it gets to hot to lay your hand
on.
Never was a problem until the summer months. notice it at the drag strip
under WOT, as soon as I lift to shift and then slam the gas back to the
floor, its dead.
I have to let the gas pedal all the way up, and then slam it down again to
resume acceleration.
If I let the truck cool down substantially it will cure the problem until it
reaches the "temp" what ever that is?
I wonder if this is TPS related, I remember some folks having problems with
TPS's on their 4.7L's.
