Have a 94 Chrysler Lebanon, when it gets warm the engine light comes on and wants to die when you come to a stop or slow down. The code is 51, air/fuel at limit. Changed O2 sensor a couple of years ago, it was doing this, not sure what code. Ran fine for over a year, started again; changed O2 again, and now in 10th month starting acting up again. Any suggestions?

If it has been over 60K, this is likely your problem. You will need to remove the timing cover to confirm. If it is intact, look at cam sensor, crank sensor, and possibly fuel pump issue.

the owner probably rerouted the fuel line because like my 92 chrysler lebaron v6 3.0 the fuel lines keep seeming to come off and the clamps always break. I have replaced the clamps 5 times in a month and replaced filters 2 times in 2 months. The only thing i could think of is that your fuel is being cut off possibly because there is no filter to clean all the junk out. Try putting a fuel filter on and see if that will work

Chrysler has a bulletin out for a simular condititon that involves replacing the pcm. Heres the bulletin number 18-005-04. This is only 1 possible cause , Fuel pressure, coolant temp sensor, thottle position sensor all can cause like problems. Seeing sensor values and fuel adaptives with a scan tool helps pin point problems.

there are no codes that say replace O2 sensors,or remove converter,Thats just somebody's guessing,When it says O2 sensor that tells the mechanic to look for trouble in that area,wiring or faulty readings,And there are four O2 sensors.
