changed broken valve spring now truck still runs rough
My dad has an 03 ram with the 5.7l and it stalled while on the freeway. He had it towed to his house and with all the info gathered on here I suspected a broken valve spring. Sure enough when I got the valve cover off the #5 spring was broke. I replaced all 16 springs, spark plugs, pcv valve, and battery. Before the replacing all this the truck would start but only with me hitting the throttle, it would stall otherwise, and it had a chatter in motor. No codes were present. After changing everything, the truck pretty much still runs as bad as before minus the chatter in motor, but I got a code that popped up (po113 intake air temp sensor high voltage). Im kinda stumped now. Ive read that the pcm may need to be reset, but not sure how to do that. Could there be a sensor bad? Any help would be appreciated. This is my first time on any forum but with what ive learned reading others posts im sure you guys will have an answer. Thanks

Well, if it was at significant rpm when the spring broke, you may have a bent valve. Did you do a compression check?
When mine broke its #6 exhaust, it was idling (fortunately). I did the same things you did, minus the battery but plus new push rods and valve stem seals. It's run like a top since then. What plugs did you use?

Just did compression test, and all cylinders good, even #5 which had broken spring. Also hooked up the snap on solus scanner to it and all sensors have good readings and no misfire detected. Checked all coils and theyre firing good. One thing I did notice is there are a couple plug wires that are arcing so im about to eliminate that when the plugs get here in 10 mins. I put in the champion copper plugs.
