Bypassing the lean burn system on a 1977 Chrysler Cordoba typically involves disconnecting or altering components of the system, such as the electronic control unit (ECU) or the sensors that monitor fuel mixture. However, doing so can lead to decreased fuel efficiency, increased emissions, and potential engine damage if not done correctly. It's important to consider the legal implications and potential impact on vehicle performance before making any modifications. Consulting with a knowledgeable mechanic or automotive expert is advisable.
The lean burn system in the 1985 Chrysler Fifth Avenue is integrated within the engine management system, primarily involving the engine's carburetor and ignition timing. This system optimizes fuel-air mixture for improved fuel efficiency and reduced emissions, particularly at cruising speeds. It typically includes sensors that monitor engine conditions and adjust the mixture accordingly. Additionally, the lean burn system was part of Chrysler's broader efforts to enhance fuel economy during a time of high fuel prices.
Harry T. Burn died in 1977.
Your headlight is leaking, allowing water to enter the lens. when it is on water will burn out the bulb.
Electronic carb. The ignition module on the air cleaner is the most likely culprit. You can try cleaning the carb with spray, but the spark advance is controlled by the lean burn module on the air cleaner. It most likely is not working. Also check the O2 sensor for replacement. A lot of owners replace the lean burn system with a standard electric ignition conversion and bypas the the lean burn system.
Chrysler used 2 models of carbs in 1986 on the Slant 6 depending on whether the vehicle came stock with the "lean burn" system or not. Short answer, lean burn models used a Holley 6145 carb, non lean burn used the Holley 1945. An internet search armed with this information should lead you to a posted diagram of your model.
if its just a little and it stops when the dar gets very hot -- its just condensation which formed in the exhasust system over night -- when started - the water is blown out -- and when the exhaust system gets very hot the water is evaporated -- that's whyits alsways good to take a nice long drive once a week - to burn that water out of the system- or the system rusts
The late seventies saw the advent of the "Chrysler Lean Burn Ignition" computer system, replacing the older electronic ignition. Unfortunately Chrysler mounted the ignition system to the side of the air cleaner pan, where it was directly exposed to engine heat and vibration, and the Lean Burn computers frequently fail as they age. This is one possible fault. Another fault could be the ballast resistor on the firewall. This is probably the least expensive part to replace to test. Another common problem that these engines have with age is stretched timing chains, which can lead to a chain slipping and messing up the valve timing. This can be tested by finding top dead center and comparing the valve timing relative to the piston stroke. Look for a "ready-to-run distributor" on ebay. That will give you a new one with HEI module, stronger spark, and more reliable. Only $45 if you have a small block engine (didn't tell us).
Chrysler did not make an Imperial in 1978. However, the Chrysler New Yorker Brougham equipped with the 440 4bbl Lean Burn engine and standard rear axle ratio (I can't remember what the ratio was/is) was EPA rated at 10 city / 16 highway.
sounds like the lean burn system bolted on side of carborator bonnet
Taking a guess, Your 1988 5th Ave has a 318ci motor with Lean-Burn Engine control. Chrysler put the control module in the rectangle box attached to the side of the air cleaner. All of the engine control module is inside that box to include the transistorized ignition system. Your distributor will have two pickup coils in it and not have a vacumn advance located on the side of it which will be another way of telling if you have the Lean-Burn system.
A lean burn system is a fuel burning system that uses an excess of air in an internal combustion engine. They provide a high air to fuel ratio and are used in some vehicles.
It will burn the whole solor system
