Hey I took a trip to Texas for a week recently and had to leave my baby sitting for a week because we went by bus to pick up my girlfriends new car. As anyone can assume my Yota got jealous and decided to act up when it saw me drive up in a 2009 Chevy Aveo When I tried to start it I found out that my battery had died so I jumped it and took it to walmart and bought a new one. Then as I started driving it I realized that it was sluggish to respond and felt as if I lost some power. While it may be hard to believe I used to be able to brake torque and roast tires in it. So when I thought I lost power I tried to do so and I got nothing. My rpms when to about 3k and topped out there and nothing happened. I'm also getting shake in my entire truck coming from the drive shaft because it only happens when the truck is in drive. When in park or neutral it idles just fine and no shake but as soon as power is engaged into the driveshaft it shakes like a dog o.O also I'm getting a bit louder exhaust and it smells like it's running rich. If anyone knows what this is I would much appreciate the help. I'm thinking I may have an exhaust leak or a vacuum pump issue. Any ideas on what to test? Oh and the Check engine light winks on and off every now and again. Sorry for the long winded description

Pull ECM codes first.

Ok I did came up as run in lean so what do you think I should check first intake manifold exhaust vacuum pump so on so forth. Any help would be appreciated.

Lean code.

Vacuum leak(medium leak most likely)

Sraying carb cleaner around suspected areas of vacuum leak and if engine idles up then you found the leak.

Check main intake hose and aitfilter housing.

Possible lack of fuel. Fuel filter. Fuel pump weak or clogged.

Well I took apart my intake and checked it and it was clean and I tried the carb cleaner but it didn't rev whilst I sprayed it. it did however rev up at a random time when I closed the hood and was driving it right after. It was as if I downshifted or something but I was only going like 10 miles an hour. Any other Ideas to try? It's getting worse My truck is topping out at 70 miles an hour....

Changed out all my spark plugs two were completely out, and I added some injector
cleaner but i'm still getting the shakes and horrible acceleration and top speed.

Oh and replaced part of the main air intake line that was cracked.

Turns out it was a headgasket and it finally blew Good news is that i'm not gonna scrap it I found a guy who will replace it for me for 130 bucks in labor if I buy the parts she should be ready to go soon I was so sad when I thought my truck was done for
