Since an auto thread was posted, I thought I'd bring up my own issue. The vehicle's fine on oil, tranny fluid and coolant (with no leaks I can find), the air filter's new and the battery seems fine. I run the thing with 89 octane gasoline for the most part.

The main issue is that the truck starts slow or not at all without a brief application of gas. It wouldn't be so bad if the thing didn't constantly threaten to stall at speeds below ~10mph, forcing me to brake while applying a minimal amount of gas, which is hell on both my breaks and my already low MPG. Sometimes when I get it started, it will run on high idle just fine, until I reapply gas, then it'll relax, sputter and die in any gear and at low speeds. When using extra gas to 'patch' the issue while in park or at slow speeds,  the truck will give a gigantic jerk when it kicks back up to normal.

As I've said before in another thread, I'm no mechanic, but since it's already had tranny work done on it, the only thing I can think of is the fuel filter or the O2 sensor (if even applicable to the model). Whenever my dad gets a wild hair to go out and look at it, he inevitably cranks up the idle, which has proven to be a futile gesture for years.

(The only other issue, aside from an old paint job and a bent rear bumper, is a wiring problem with the lights that require a bit of driving around before they come on, which should be an easy fix.)

Suggestions?

Not a mechanic either but sounds like a transmission thing or alternator perhaps?

Fuel pump going out I think.


Not a mechanic, but I had essentially identical problems and that was the issue...

Fuel pump?

It's dying from lack of gas by the sounds of it.

sounds like a carburetor issue.  Since you say the high idle is fine, I'd be hesitant to condemn the fuel pump right off.

if I were working on it, i'd start with a good baseline.  Make sure the fuel filter, spark plugs, wires, cap & rotor are up to snuff.  Make sure the mechanical advance and vacuum advance are working properly.  Make sure it's correctly timed.  Then I'd check to see if the EGR valve is stuck.  I'd look for vacuum leaks.  And then i'd look at the carburetor.  Choke operation, mixture adjustment, etc.

'87 Dodge?

Run that think with the lowest octane gas you can find.
It doesn't have the compression ratio to use high octane gas.
If anything, it'll run worse on high octane gas.

I'd run lower octane gas, check the spark plugs (gap and fouling), check the distributor.

Yeah, it runs fine at high speeds. Stalling while parked or backing out is one thing, but slowing down without applying gas and brakes for a stop light is the real personal danger zone with this vehicle. Stalling out in an intersection and losing power steering = .

There is a smell after driving across town, but for all I know it could just be the breaks wearing down faster than normal.

I've ran it for awhile on lowest without any noticeable improvement.

burning smell or strong chemical smell?

Burning, actually.

edit: I'll try and put a video up when I can.

That would probably be your brakes complaining.

is this a 318?

Those are the cheap ones.

Fuel filter is a cheap fix, too.  Truck is old enough, the fuel tank could be corroding from the inside and throwing chunks into the fuel filter.

Vacuum lines...  Tons of little $1 parts that could cause low idle stalls.

Sounds like a fuel or spark or vacuum problem more than a transmission problem.

Also check the air filter, I have a 95 ford ranger and was having idling issues at low speeds like it wanted to stall all the time. Turn out the air filter was clogged. It didn't seem that bad but it was the problem.

Also replace fuel filter, another cheap fix and I'm sure it wouldn't hurt it especially for a 87.

Air filter's been replaced recently. I'm going to get back to looking at the thing this weekend and checking out some of the things suggested in this thread. As of now, it's a hobby vehicle.
