Found on Road Dead

[2manymustangs]

While driving on the 40 last Thursday night the water temp gauge pegged hot, oil light came on and the truck went into limp mode. I pulled to the side of the road and the truck showed no signs over overheating. I turned the key and the temp went to normal and the truck drove fine. 20 miles later it happens again. I pull over, turn the truck off, turn it back on and back to normal. This happened about 15 times between Newburry Springs and Needles. I figured it was a bad temp sending unit so I tried to disconnect it but the problem persisted. I ended up parking in my buddy's river house driveway in Needles and sleeping in the back seat. It was 2am by then and I was tired.

The next morning I fire the truck up, grab my boat out of storage and and head to Havasu. All is good. Later that day I'm driving to Interstate Batteries from the Islander and it happens again. So I stop at Orielly's and pick up a new sending unit, plug it in and boom, it happens again. So I called Ford in town and they said they couldn't touch it til Monday. I then called Tri-Tech Auto and they said to bring her in. The guys there were awesome BTW! I told them I was en-route to get batteries and they had Interstate deliver to their shop! .....So they plug it in and its showing a code for the cylinder head temp sending unit ( I didn't know one existed). So they replace it, clear the code and it seems fine. We go to back out of the garage for a test ride and boom. Temp gauge pegs and truck goes into limp mode. Plug it back in and we get a misfire code. #6 misfired 86 times and #10 showed only one. So they replace the coil on #6, clear the codes and the truck drove great all weekend! Last night I'm headed north on the 95 (just passing the airport) and it happens again! So I unplugged the head temp sending unit and made it all the way home with out going into limp mode and the temp gauge pegging hot.

I have no clue what the hell to do next. Anyone know a good Ford Tech around OC?

I would invest in a code scanner OR better yet, the OBD tool (plugs in service port)/software that you can monitor real time with your smartphone...

Was there any actual sign of the truck really getting hot OR do you suspect electronics/sensors/wiring?

I would think that there would be codes for o2 sensors if there was an injector issue and the misfire issues if it was a really bad misfire... Just a guess...

Not much you can do these days without a good scan tool...
