Hello:;
This sounds like a fuel problem at the carb. What it's doing is termened hunting a nd can generally be corrected by a simple adjustment of the carb. Engine at idle and neutral set rpms at lowest idle , around 640 rpms. then adjust the a/f ratio screws to balance carb. Screw both screws all the way in, do not force ,or needle and sear damage will occir. Now back each out to 1.5 turns That is your start point Adjust one screw in and out slowly until you you feel its best effact on ide whicjh should slightly increase. repeat with other screw, in and out slowly . listening to the engine idle. if idle has increase due to your adjustmebt, repwat process after lowering the idle speed again with the idle screw. When you get to the point the screws no longer affect the idle the engine show sound and run smoothly at idle, make sure you resert the idle to 650rpms for an automatic trans and 650-750 for manual trans. I hoped this helped- good luck.. If it still does it, the carb may nrrd the float checked and st.

I have 1990 ford f150 5.8 liter it idles high when in park and idles about 1200 rpm when in gear and sometimes surges up and down. i have clean the idle control and check showing 12.5 ohms still won&#


One common problem is a vac leak or a sticking throttle plate.
The computer controls idle speed by how much air is allowed into the intake. The idle control valve could be sticking even tho you have cleaned it, or have a faulty motor.

2001 Ford Ranger V6 timing chain


Hello;
The Ford motors are pretty good. I had 280K on a 2.9 V-8 that only needed the oil changed every 3K. Unless you have fluctuatuation in the timing then you should be ok.
These engines use a chain rather than a belt and have excellent life.
Thanks;

1994 ford ranger extended cab 6 cyl fuel injected 2 wheel drive automatic


This year of ranger had a few flaws, In one case, a break power booster was robbing the vacumm, you can test this by plugging it off and seeing the differance, but you will have limited brakes. This model year had a problem with a vacuum leak on the manifold. You can check these in many ways, but please don't use starting fluid. The rear of the manifold usually on the drivers side where it seals to the block.
Also, in 2 other cases a cracked head has gave me the same problem. It is caused from a loss of vacuum.
