Why would a 87 Chrysler fifth ave stall out when you push on the gas to much?

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.

Does a 1987 Chrysler 5th Ave have an ignition control module and exactly where is it located?

The ign control module is in the air cleaner and is calle the "lean burn system". Your unit is 20 years old and probably needs replacement if you car is running poorly. Do some research on the lean burn system and you will find that it was an over complicated electronic ignition. Mopar has a electric ignition replacemen kit to bypass the LBS. This is an option to replacing the lean burn computer available at NAPA for about $135.00. The replacement is easy fix (about 4 screws and 2 plugs) and will fix your ignition problems, but if you plan on driving the car for a length of time get the conversion kit ($200.00).

Where is the control module in an 1988 fifth ave?

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.


How would you go about bypassing the lean burn system on a 1986 Chrysler Fifth Avenue?

In order to test the lean burn, you simply unplug the harness from the module. Then, purchase a points distributer from an older version,1966 to the 70's. Then hook the ground wire from the distributer to the negative on the coil, and the car will start. it will run on the mechanicals, but in order to find vacuum you have to find a port with no vacuum at idle.
