Post Lean Burn Help

I was wondering if anyone would be able to help me. I have a 1988 Pylmouth Gran Fury with 318 2 barrel. I'm suspecting the Lean Burn isn't working properly. It has a stumble whenever you touch the gas. The oxygen sensor has been replaced as with the distributor cap and rotor. Anything would be nice. Thanks so much!

Took the Electronic Lean Burn system out of my 77 Newport, and replaced it with an electronic ignition system. Probably the best advice I could give you, had no problems since.

I also have the lean burn and plan on replacing it. I don't think Chrysler even understood the lean burn system.

Is it hard to get rid of the Lean Burn system? How expensive is it? I'm wanting to get it off so bad. Thanks for your help!

Question

It has been quite awhile since I worked on a lean burn, but doesn't an '88 have an ECM, whereas the '77 had the control unit mounted on the air cleaner asm.?

I think we may have two different systems here.

CORRECTION: The Lean Burn main control box is attached to the drivers side of the air cleaner.

Cool

I have de lean burned a 400 out of a 1977 Newport but it went into an electronic equipped vehicle, making it easier... As I see it you will need a new distributor (one with only two wires coming out), the old coil should work fine, then you'll need a new ecu and possibly a voltage regulator/ ballast resistor. I'm not 100% sure about the ignition switch in the car but I'm sure you'll be able to gear it up to work without too much trouble. You'll need to find a wiring diagram of a dodge electronic car.
A few .000's, ( around .023 is my preference) off the heads and a new cam does wonders for those smog engines

Direct Connection used to sell a kit to get rid of the lean burn system, try your local Dodge/Chrysler dealer catalogue. I seem to remember it consisted of a new distributor and ignition module with the correct connectors to fit without cutting.
