New truck, several issues
hey guys. been awhile since my last post.
I bought myself an 87 F-150 with a 300 and a 4 speed manual.
It has several issues. First of all, when i drive down the highway about 55 mph and try hold it at a steady speed, the truck seems to stutter or miss. but when i give it some gas it stops stuttering and goes how its supposed to.
second, if i take off in second gear, the instant i let the clutch all the way out the truck stutters or misses once and then takes off agian. It doesnt do this every time, but often.
third, when i rev the truck to about 4 grand, not that i need to, the oil pressure drops to nothing and the "engine" light comes on.
any and all help is appreciated

My guesses would be that the plug gap is too wide or the wrong plugs are fitted or the plug wires are bad.
Maybe time for a tune-up, plugs (Motorcraft), wires, fuel filter and air filter?
As for the oil press it would sound like a bad oil press sender or bad connection to it.
Just my opinion.

Yea, i guess it could be time for a tune up, tho the wires and cap look brand new.
Could it possibly be the in-tank fuel pump? Right after i bought it the one in the front tank went bad so i just got one from the junk yard for free to get me by. The rear tank doesnt work either.
As far as the oil pressure goes i think ill put a real gauge on it and see what kind pressure i get then.

I remember my 90 used to do the stutter thing when travelling at speed with light accelleration. Step on the gas and it was fine. I don't remember what I did to correct it, may have been a fuel filter. Check your codes and do the wiggle test on the sending unit.
