Chrysler Repair: 92 lebaron gtc chokes and wants to stall, lebaron gtc, exhaust gas recirculation

Question

I have a 1992 Lebaron GTC  3.0 with 88,000 miles on it. The problems  I am having are as follows..... I  would stop at a  light or slow down, and the car would idle rough, the battery gauge would go down and fluctuate ,then stall  and I can start it back up  with no problem..  or when driving, the check  engine light would flicker on, then the battery  gauge would go down and the car wants to stall while driving.( it chokes). This happens whether the car is Cold Or hot..... Now  when I have the  Heater on defrost, the battery gauge goes down, the headlights and interior lights dim, as  soon as I  turn it off its better, but it happens more  when the heater is on..... and there are NO codes coming up.. .

I have taken it in to 2 repair shops.  Diagnostic test came up with no codes so they repaired these items...
Distributor cap and rotor, Wires, Plugs, fuel filter, fuel injector cleaning, oil change
alternator and battery.

2nd shop.. did the  diagnostic tests and again had no codes. they  tested the battery, charging and starting system,  ignition system. they could not figure the problem out either

if anyone can help me I would appreciate it. As I said  I have taken it into 2 repair shops and  spent all sorts of money I don't really have and the problems still there..

Thanks

Hi Carol,
Was this car originally delivered in California? If so there is a pollution control part called an exhaust gas recirculation (egr) valve which if it get gummed up and stick slightly ajar when you are at idle it will cause a miss and/or rough idle but not be detected as a fault. Let me know and I can tell you how to fix this yourself. Otherwise, you can keep checking for fault codes yourself using your ignition switch:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the check engine light, which remains 'on', to begin to flash, pause, flash, etc. Count the number of flashes before each pause. Then do it again to be sure of an accurate flash count. Then combine the numbers in pairs in the order of appearance. If you just get two sets of 5 flashes each, e.g. the number 55, that means 'end of readout' so you have no fault codes. Anyother number is a fault. Let me know and we'll go from there, or you can go to www.allpar.com/fix/codes.html for a code translator.

I just saw your question in the 'pool' to which it had been referred after 'shopteacher' dropped out of the service, apparently.
