Hey everyone I have a 92 k1500 350 tbi it runs fine down the road. However when at a stand still it acts like it wants to die when you stand in the throttle it also does this when you stand on it while driving. have done a complete tune up minus the fuel filter. When i adjusted the timing I noticed it looked like one of the injectors was not spraying fuel as well as the other. Thank you for any advice or direction with this issue because it is keeping us out of the mud...
