Hello. This is my first time posting on the website here. I've learned alot so far and i'm hoping you guys can help me out. My truck has a bad hesitation when i try to slowly accelerate in overdrive at around 1800 to 2000 rpms. If I press on the gas till it downshifts to 3rd then it's ok. Like I said I have a 96 sr 3.5 dohc 82,000. I don't know if the people who owned it before me had the new lower air plenum replace or if the 96's even needed it to be replaced. I've read that the 95's did. Anybody got any ideas? Thanks!
