Hey guys,
I have a 2001 chevy 1500hd with the 6.0Liter enigne. Over the past couple of days the truck has not wanted to start and is running rough. When I step on the gas the truck wont get up and go like it use to. Could my O2 sensors be bad, any help would be great. It just happened the other day, I took it to the local repair shop and they put the computer to it and everything came out fine. All the spark looked good, but something still isn't right. I barely made it over a bridge today.
thanks,
Tyler

 

check fuel pressure, change fuel filter, check catalaytic converter, check that there isnt a stupid squirrel in your air box,
i would start at the fuel filter or pressure if you dont have any codes in the computer.
check out spark plugs also, fuel filter is probly cheaper...

 

My buddy had the some problem, ended up being the computer chip for his fuel injectors. has this just happend overnight, or did this take place over time?
