'93 c1500 stuttering/hesitation at take off
Just started stuttering when I just start to pull out. Idles fine. Runs fine a high speeds. Accelerates fine. Whenever I push the pedal just slightly, it stutters/hesitates and then takes off. Plugs, cap, coil and wires, air filter are very recent. Any recommendations on what to check?

I bought some cleaner so I will give that a try. The weird part is that it does not do this when I first start it. I can drive it for a few minutes without the issue. I know the OBC does not kick in until the temp gets to a certain level. Seems like it starts to do that once it gets to temp.

Just posting a follow up. I saw a incident where a guy replaced his injectors and the issue went away. Since it has 135k, I decided it would be worth it anyway. I found a new set on ebay for $90. I replaced those and the throttle position sensor and she is now running like a champ again! My feeling is that it was the injectors, but didn't have time to change out one at a time.

I am also having similar issues I replaced spider Injector, fuel pressure regulator,fuel pump,fuel filter, spark plugs and wires . With all this when I run my 96 c1500 for a while the problem goes away but once I hit about 60 it does it again and then it's fine after that. At first it was even idling rough so I tweaked the idle screw now it idles fine but still hesitates off the line. I cleaned the throttle body completely. I'm thinking it may be my throttle position sensor but I do not want to spend money on something I don't need any ideas ?
