Re: 91 c1500 stutter on acceleration
Can you give us a better description of what is happening? the truck seems flooded once it is warm, I would compare it to a choke staying open on a carb when it is warm and you are giving it full throttle
Does it misfire? Is it dropping a cylinder or two on acceleration?It doesn't misfire
Is it only on hard acceleration, or any acceleration?Mostly hard acceleration, but the warmer the truck gets the worse it gets and even moderate acceleration causes the problem, it idles perfect
Does it feel like the truck is trying to pull a train? No power?The truck feels powerful, but the stutter is not allowing it to show its true power
Are the spark plugs Black with soot?I haven't checked them again since i replaced them
You replaced the ignition parts so you must have thought it was an ignition problem, is this correct.No, i was just doing my due diligence and replacing a lot of ollllllld parts
Have you tried buying your fuel somewhere else? Sam's Club, Chevron, Shell.... all the same problem
Have you taken a fuel sample to see if there is water in the fuel?
