Question about 1998 Dodge Ram 1500 4WD

1 Answer

1999 Dodge Ram 1500 runs ok til warm, then..

My 1999 Dodge Ram 1500 5.9L runs ok when it starts, but as it warms up the idle drops, it acts like it will stall(and occasionally does). Also on the road it works ok sometimes and floods other times will barely run. I'm getting P0172 as a code, ''System too rich,bank 1''. Just not sure what to look for in reference to that. Any ideas?

Have your battery tested. When the battery has a problem the dodges will act this way.

The temperature gauge on my 1999 Dodge Ram 1500 is not working. The temperature sensor and the thermostat have been replaced.


Check the gauge by holding in the trip odometer reset button and turn key to run,hold button for 10 seconds this will iniate a diagnostics on all the gauges,and lights if gauge doesn't move during this test replace gauge,if it does move then check the wires on the plug at the engine coolant temp sensor (ects) you can check the sensor by using a ohms meter by unpplugging it and check ohm's or resistance when cold and then start engine as the engine warms up the ohm's reading should gradually lower as the sensor is a thermister and as it warms up the resistance will drop.

1998 dodge ram pickup 318 eng. engine idle rough on warm-up engine idle rough after warm-up shutting off engine and starting back up engine also runs sluggish in over drive at a low idle. I have...


If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?

1999 dodge 1500 5.2 liter warm up issue


is there a CEL? on the newer cars like this they have o2 sensors that send a signal to the computer that tells it to richen the fuel mixture until it gets to a certain temp these sensors also help the computer maintain a stoichmetric A/F ratio of 14.7. this acts like a choke on old cars. there are also other sensors that pertain to this. if you can try to get it on a diagnostic to pin point what sensor is not functioning correctly.

if there is not a vacuum leak it seems that the signal wire to the MAP is either open or shorted to 5 volt reference wire. if not either of those may be the PCM
