I have a 1994 Ram 1500 with a 5.2 with 190,000 miles
Yesterday the truck started running rough.
The engine would race and come close to stalling
I replaced the Throttle position sensor today and it is still doing it
The truck stalls when i come to a complete stop and in reverse
I tested the codes and code 37 came up two times after i reset it
and a egr soloinde number came up, and a oxygen sensor number came up.

Has anyone else had this problem

 

check the fuel pump a bad one can cause a bank one miss code. not sure if that's 37 or not but it sounds similar to how mine was running when I got it and my problem was the pump.

 

sounds more like an o2 problem to me.

 

yeah ryan thats what I though when it happened to me. After replacing both o2 sensors and a few other parts I finally broke done and changed the fuel pump. Now it runs like a new truck. Don't get me wrong I'm not saying that's the problem for sure just something to check.

 

02 sensor would def. give you those problems....try replacing the pre-cat sensor and see what happens
