Talking Got the H3t Back

Well a bunch of work has been done but the ''Service Traction Control'' still showing but driving it with the traction off it is running great but I did notice with the light switch set at Auto the headlights are not coming on. Could this be a clue? They do work when switched to on. Anyway gonna drive the crap out of it this weekend and see where it takes me!

If I do not turn the traction control off there is a shudder in the LF when letting up on the gas approaching a light ect.

P0300 is random misfire. The others I can try to look up tomorrow.
clean throttle body. Clean mass airflow sensor. Replace spark plugs with AC Delco oem. Replace air filter. Make sure air resonator box hose isn't dry rotten.

Thank you for your reply Air flow sensor was cleaned then replaced The truck is not misfiring even though the code shows. If fact the truck is not doing anything the 4 codes show it doing. Another member suggested it might be a bad instrument cluster. Your thoughts?

Was your fuse block messed with? If so, maybe check that it is back in correctly? Battery terminals have been changed? Just throwing it out there, wish I could be more help.

GEEZ another problem......... I have been driving the truck and it has been doing good with check engine light on and service Traction Control warning. I turn off the Traction Control while driving with the button. Last night while accelerating to get on highway not much power and the the REDUCED POWER indicator shows and check engine light starts flashing. I was able to limp home doing 45 mph, Now what should I be looking for? Using the search feature I see clean throttle body, PCM, replace spark plugs & air box. Does it ever stop with these trucks?

If the CEL was flashing, there should be a misfire code in memory (P0301 would indicate misfire on cylinder number 1, for example). Clear the code, swap the coil from whichever cylinder was misfiring to another cylinder. Go for another drive and see if the misfire moves to the cylinder where you mounted the suspect coil. If the misfire moves with the coil, replace that coil. If not, post back and we can go from there. Which engine do you have?
