I have a 1990 ford f250 with 302. Starts great and idles just like it is sapost to. But as soon as I drive it it idles around 2000/2500.
When first start it my truck will idle just as it
is sapost to when cold. As soon as you
step on the gas pedal it idles at 2000/2500.
When it worms up it will idle 1000/700. Now
has just started to sometimes die When
stopped. I have replaced all the senses on
the motor. Except for egr and map oxen
senser. I run grate going down the road. I
get around 14 miles to the gallon.
