Asked by Brandon Oct 17, 2018 at 09:10 AM about the 2002 Dodge RAM 1500 ST Quad Cab RWD

Question type: Maintenance & Repair

Jus fixed head gasket and it showed a misfire on
4&6. Changed plugs could packs and injectors.
Reset the pcm and checked for stuck valves or
rocker off cam. It is still running like it's misfiring
but only code is 037 O2 b1s1. Diagnosis?

My 94 dodge ram 1500, 5.2L, runs okay but began using lot of fuel. Had trouble codes 37, 32, and 51. Cleaned throttle body and checked for vaccum leaks or bad hoses. Code 32 gone away. Cleared code 51 which according to Haynes manual is not supposed to make the check engine light come on. Their is no code 37 in the Haynes manual for a gasoline engine on the 94 Ram. Their is for diesel engine. What is it, where is it at and how do I correct the problem. 51 I know is the O2 sensor. Truck runs great, shifts fine , but is still using more fuel than normal. Been reading about code 37 and transmissions, don't think my problem is there. Any help ? 5 Answers

Cannot get the Code 37 to clear, can disconnect the battery and the code 51 clears, The code 32 has not come back but 51 comes back. 37 does not go away. Engine light will not come on after starting...
