I have a 97 E-150 4.2 L V-6. I replaced the fuel pump then began having problens with the Idle Air Control sensor. Replaced it twice, ran good for a couple of hundred miles, then Service Engine light came on again. Now it is intermittent, on and running bad, then off and running fine. Last check with the reader shows problems with the fuel injector sensors on the injector rails. Reset the computer and it has run fine, so far...
Is it the computer, the sensors or what? I have run out of ideas...
The van has 450,000 miles on it with an engine rebuild about 25,000 miles back. Other than this problem it runs great and should have plenty more miles to go in it.

There are no sensors for the fuel injectors, on the injectors, or i the fuel system at all.

I would offer a WildAssedGuess (WAG) that you have a vacuum leak some where.
