Hesitation when shifting/accelerating
I drive a '97 Chevy Blazer 4.3L 4x4. I am having a hesitation problem with it. Usually it is when it's shifting from 1st to 2nd...but sometimes it does it not even shifting. It kind of shutters and bucks and doesn't want to go faster. And it only happens when I'm light on the throttle or easing off of it. When I press the gas down about halfway its fine, and anywhere between that and flooring it is fine. I took it to autozone and had them to the computer thing on it and they got a code for random misfires. So far I've changed the MAF sensor, had the fuel injectors cleaned, had the fuel and air filter changed, and had the tranny fluid drained and replaced with a new gasket and filter. I found out today that I have a slight rear differential leak but nothing too bad, and I'm not sure if that could have anything to do with it. If you could give me some advice as to what this could be I'd really appreciate it.
