Possibly OT: 1984 Plymouth Reliant

Hello all...and apologies for the somewhat off topic nature of the question. Although, if it bothers you, I guess the car can be a Dodge Aries for the course of this discussion. :-)

I have a 1984 Plymouth Reliant with the 2.6L Mitsubishi engine in it. The car runs and drives, but it idles entirely too fast and diesels when turned off. "Punching" the gas when in gear results in a stumbling engine for a few seconds before the car finally decides to move. An attached tachometer shows an idle speed of some 2,000 RPM. I have the Chrysler FSM for the car, but don't really know where to go from here. I'm not even absolutely sure which type of carburetor the car has on it--neither the standard or feedback type illustrations match precisely what I have. I did find the throttle position sensor, which appears to be present on only feedback-type carburetors.

I did ask a nearby mechanic about the car, but he didn't seem all that interested in working on it and commented only that the "choke isn't working". I'll confess that I don't know for sure, but the choke plate in the carb *does* open up when hot and shut when cold.

What I'm looking for are some things to check for, because I really don't know of anything else to look at. What are the odds that a Chrysler dealership in this day and age would be able to work on this car?

Its a Mikuni carb and they are high dollar if you can find one. There aren't to many people that want to work on those things anymore. The problem you are having is not something that you can get an answer on line. If you vehicle is idling high and diesels the first thing to check is the throttle plate. I have 1986 2.6 minivan drivability book to sell for $25 if you want. e mail if interested.

Wax pellet controlled choke, with a gear drive on the fast idle cam from what I remember of my 95 LeBaron. Tricky to set up properly, and not terribly reliable at the best of times. I know guys have put Holley Weber carbs from 2300 fords or Vegas on and had significant improvements, across the board. Better driveability and fuel economy with definitely no loss of power (perhaps an improvement)

Hi!

Anyone want to buy one that works well enough to let the engine run? :-D

(Yes, that's a joke. Unless you really want one and make a corresponding offer!)

I'm not looking for a cut and dried solution to the problem, just some good hints that might give me some stepping stones into understanding just how this carburetor works. I'm not totally stupid (nor am I an expert) about these things, but this thing is making me feel that way.

Per your suggestion, I'll look at the throttle plate.

What does this talk about, and why would I want it? I'm not trying to be rude...I just want to know what it might have to say and what I might come away with.

In all honesty you probably have problems with the Carb, I don't think you can get parts for this thing any more and if you can even get a reman carb it is probably going to be junk from an aftermarket supply house. There are to many things that can go wrong with this Carb. one is the wax pellet and many other problems. You may even have a vacuum leak somewhere else under the hood causing this problem.
