What can cause the air to fade in and out as rpm needle jumps... almost like the car is gasping for air. The car just of recent kindda shakes and make noises... Especially when reversing it... it has even shut off once when I reversed into a parking space,

Help.

Check all the hoses for a vacuum leak

Im gonna have someone check my hoses and everything.... I did get a recall from the dealer in the mail.. I'm not exactly sure what is for so I guess I should take it in.

Also the car's at 97,000 so is it time for a tune up or what should be performed at this point?

BTW, I also noticed a knocking noise from underneath the rear rear of the car when I shuts it off maybe a few minutes after. ???

That knocking noise is the EVAP system depressurizing

your throttle body could be gummed up and sticking...you've got quite a lot of miles on it, so it'd be worth checking...I know my car felt like it wanted to stall when I ran the a/c before I cleaned my TB.

also might want to pull your plugs and make sure they're gapped ok...you'd be surprised at what can happen to them over time.

other than that maybe your catalytic converter is clogged and/or one of your oxygen sensors could be going bad....could be that's it's not gasping for air but rather can't exhale.

my advice is to clean your throttle body first since it's the easiest and cheapest thing to do.
