New to your site, usually on the Charger site for my 66 Charger. Helping a co-worker with problems with his 1995 Dodge Truck, 5.2 auto regular cab, 80,000 km with stalling issues. It never threw a code and all the local shops didn't have a clue. So before posting here, this is what I have done so far according to the many threads concerning this problem. Pulled throttle body and cleaned a per instructions. Cleaned air control valve. Replaced O2 sensor (end of it was cracked). Slapped in a new set of plugs. Before stating with all these repairs, truck was sluggish and didn't pull like it should. Took it for a ride after all this and truck was running great. Much more responsive and ran smoother. But later while cruising down the highway it started to buck and backfire, engine check light comes on
. Stopped backfiring and returned home to check the codes right away. So this is what I got according to the chart, codes 37 & 32. So now what
. I will take a look at the egr valve and maybe give a thorough cleaning, but the other code 37 has me at a lost. Where do I start to look at for this one. Also on a personal note, my co-worked is fed up with this truck, he wants to get a Ford
, so I will have a chance to by this one from him
. Truck is in great shape. Thank you for your time in advance.
