Question about 1987 Toyota 4Runner

2 Answers

Low idle, stalling frequently

My 4runner stalls when I take my foot off the gas and stop, (manual tranny), this happens once my truck is warmed up and will usually happen for a while right after it has come up to temperature and will usually go away after driving for a bit. Occasionally it wont happen at all. Recently I've put in a new O2 sensor, Cold start sensor, ignitor, plugs and wires... Once warm it idles just over 500 rpm, is this normal for this vehicle? Other than the stalling issue, the truck runs great!

    It seem that once the truck gets to a 1/4 tank it's starts to run funny. It starts running rough and stalling. When this is happening and I try to press the gas I get no response .

I would look at the ignition system. Possibly a faulty ignition module or coil ( if you have a single coil ) Multiple it will generally be one coil that goes bad and results in a misfire code. Or if it's the ignition module it might not throw a code at all, And it might test fine if it's had a chance to cool down before it's tested.

Have you checked the charge on the battery? How bout your connections at the terminals. Vw are very sensitve to voltage drops. You might even have something thats draining your battery

Loses power on steep grade


Sounds like you need a clutch replacement.

Try this. Go somplace where there are no cars, and no possibility of running into anything. Stop the car. Set the park brake. With the engine running, put the vehicle in 1st gear. Hold the foot brake pedal, and give it gas, and let out the clutch slowly.
If the engine does not stall real quick, the clutch disc is bad.

Hi

Does this only happen once the engine has warmed up? if so, does the truck accelerate if you put your foot to the boards? If so then have the O2 sensor checked out.

Otherwise, have the fuel pressure checked out, it sounds like it may be a wee bit low.
