Hi, I have a 91 Honda Accord, I love this car but there are many problems and I was hoping you could give me some guidance for DIY? For a few months there has been a sort of swishing sound at a certain rpm (2000-3000) I have a magnaflow catback exhaust (not by choice) I think it's an exhaust leak but not sure how to fix it. I also have a popping sound coming from exhaust at idle and after high rpm. And two days ago I went over a huge bump in the road and since then I can't make it up hills. acceleration between idle and 2000 rpm is really sluggish then picks up, shifts hard and it feels like it's being held back for 3-6 seconds then back to normal? car has always had a stiff transmission (it's auto) but it feels much worse now. I'm sorry I know I'm asking for a lot of answers but it's my first car, I kinda got screwed, but I love the car and I don't wanna see the tranny drop thanks man

 

You state you have an an exhaust leak....find and fix it.

If you hit something that hard, would it be a reach to say the cat has broken apart and causing an issue?

I'm assuming the CEL is not on and there are no stored codes?
