There seems to be an issue in my Maxima where when I slow down while making a turn and go to put gas in to accelerate, my RPMs dip down very close to 0. So I noticed that a coolant hose has snapped off so I replaced it and I'm still having the same problems, Anyone know whats up?

I doubt a coolant hose would cause that problem. There are no CEL codes? Sounds like a fuel problem. I am guessing here.... could be a fuel pressure regulator? Clogged fuel filter? Just guesses......

well im currently replacing my exhaust because of a major exhaust leak so ill report after to see if that fixed anything. But oddly enough I don't think the CEL ever came up.

sounds like a massive vacuum leak. Start checking the vacuum lines. Have you done any work on your car lately?

Ive only replaced the coolant hose. I'm currently changing the exhaust.

Car a 5 speed? Same thing happened to me like 2 weeks ago. Everytime i push clutch in rpms dip to 0 almost cutting tye car off. Culprit ended up being IACV. Easy fix.

Sadly, it is a automatic haha but what is that? IACV and those aren't on automatics?

Is there any pictures I could take to help?

Start by checking for vacuum leaks, and clean your IACV. Very simple to do. You'll be surprised as to the amount of gunk you'll find on and around the brass cap inside the IACV. Clean your TB too while you're at it, and ensure the butterfly is closing/sealing 100% and not open slightly due to build up of gunk.

Hey, I just finally swapped my exhaust last night. Interesting I guess ill look at that next, do you think you could send me some pics of where the IACV is?
