Hey everyone,
I’m going to try and give as much information as possible.
Truck info:
1984 Ford Ranger 2.3L
1 BBL Carter YF Series 7632S
Manual 4-speed
No A/C
No Power Steering
Problem:
Rough rolling idle, will idle smoother with no rolling if choke is closed, but still not extremely smooth. If the choke is closed it’s almost as if it has small dips in idle, almost as if it is misfiring on one cylinder.
History:
I got this truck from my father; it has been in the family for over 10 years. When I picked it up he had already taking it to the shop for not staying idle at all, if you let off the gas it would die every time. They said needs a new carburetor. I proceeded to take it back home, having to start it every time I came to a stop. I took off the carburetor starting looking at it and noticed the throttle butterfly rod seals (the rod connected to the throttle that extends through the bottom of the carburetor that is attached to the butterfly, those seals on the inside of the carburetor that keep gas from protruding out of the sides of the carburetor. hope that makes sense) were worn. Gas would leak out all over the manifold. I tried to buy those seals, no luck. I then bought a remanufactured carburetor. I put it on and the truck started running fine again. I don’t know much about adjusting a carburetor, but did the best I could from what I found on the internet. Still if I recall the idle was extremely smooth, engine would shake enough to make my shift lever move back and forth. The truck ran fine for few months, except the occasional big backfire after I shut the engine off. Finally I went to Lowe’s one day, came back out started the truck up started to have a rolling idle. Drove it home, went to leave somewhere else, and again if I let off the gas it would die. Since then over the last couple of months I’ve done a few things to try to get it running again. Started off looking at the ignition system, noticed a few wires had the insulation rotted off. I replaced those, but still no luck. I then tested the coil, noticed it was starting to get out of specs, replaced the MSD Blaster II coil, still no luck. I proceeded to check vacuum lines, and ended up just taking off all the smog crap, until I was left with the PCV and the vacuum advance for the distributor. Also I replaced the fuel filter, and put on a manual choke instead of the automatic. I finally started adjusting the idle screw and fuel mix. Air/Fuel screw is 1.5 turns from seated and the idle is all the way in. Now I’m stuck with a rough rolling idle, but will idle smoother with no rolling if choke is closed, but still not extremely smooth.
Please any suggestions would be appreciated.
Thank you
ps i also checked the plugs and the plug wire, seem to be fine.
