Not running right

[EVOrider]

I've got a 1983 Ranger with the 2.8L....2wd and manual transmission. It still has the EEC-VI.

When cold, the idle is rough. Once warmed up though, the idle is smooth.

When the engine is still cold and whenever the engine is placed under a load, it looses power. It is like it is not getting fuel.

Once the engine is warmed up and engine is placed under a load, it sometimes looses power. I can be traveling 70 mph and all of a sudden, the truck looses power. I then floor the gas pedal and power returns like it should. This problem does not happen all the time though.

Why does the truck run great at wide open throttle?

I will be checking for codes sometime later in the week or during the weekend. Does it sound like a fuel filter problem to anyone.

Thanks for anyones help...

two words: duraspark conversion

Possibly a fuel delivery problem, possibly a computer problem. Start with the codes.
If you don't need factory smog where you live, start with a DuraSpark.
Let us know what you found, then we might be able to help

how bout start with a tune up and then check the pcv valve and check for vaccum leaks cause the duraspark looks like a bitch to do..
