Asked by Apr 15, 2016 at 11:28 AM about the 1994 Chevrolet C/K 1500 WT LB RWD

Question type: Maintenance & Repair

When I try to take-off from a stop sign the engine sputters and acts like it's going to die. After I get up to 20-30 MPH it does pretty well. The problem is just when I'm taking off.

I suspect that the air temp sensor is not doin' things right~ https://www.google.com/search? q=1994+Chevrolet+C/K+1500+air+temp+sensor&biw=1360&bih=64 9&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwiO7vfZ- 5DMAhWBpR4KHXacBRsQsAQIGw

This is a common 4.3 problem usually EGR (exhaust gas re circulation valve) partial function it also effects higher speeds 50-60 sluggish vehicle feel not effected by being hot or cold. My shot in dark without vehicle diagnosis.

Check the air hose that is connected to the transmission module located on the passenger side of the transmission. Most people don't think to look there. The hose is exposed to many elements therefore it could have a small crack that would cause the engine to sputter at lo idle. It takes all of about fifteen minutes to change. Do not use the old clamps get new ones. I had to replace mine twice first time it was split. Two weeks after I installed new one it looked like someone took a razor to it. So when you buy the new hose inspect right there at the parts counter to make sure there are no splits in the new hose. Good luck yet I am sure this will fix your sputtering and backfire on a start up. Also it will eliminated hard starting.
