ok guys look im new to the site and im new to the site i have a few ?s about my car. ive only had it for about a month and ive noticed a few things and one of them is the car has its times it feels like the car bogs down and then picks up all the sudden so i put new plugs and wires on it itcleared up for a few days and then the check engine light came on its throwin some emission codes so i was wondering if its something i should worry about or wat should i do? also ive noticed every once in a while i hear a whinning noise it only makes it when i give the car gas going up hills could it be the rearend or what do yawthink the car has 20s on it i dont personally like them but i bought the car that way but could the wheels be causing this? i think that im just parinoid due to i bought the car from a dealer and ive never owned a trans am so ill really apreciate your help

Paragraphs please! Seriously though depending on how loud the whine is it may be the rear end, or it may be nothing. 20's make noise too. Take your car to a reputable shop and get it looked at. It's cheaper to replace the rear end before it blows up. As for your codes, it's probably your cats stopped up if they are still on the car.

post the code that it is throwing...could be cats and could be covered by warranty depending on mileage.

its throwing the code p1406 it says its a emmisions pump i have always removed all the emisions junk off everything ive owned but cars are different so just wanted to know if i should waste 120 for the pump just to get my check engine light to go off
