check engine light stays on, replaced plugs, wires, head gasket, valve cover, timing belt, replaced vacuum lines and coil pack..it failed an emission test yesterday, there were 3 codes present: P0106, P0132 and P0300. but it runs great on highway just jumps and jerks at idle in drive

I recently had my timing belt and valves fixed..2000.00, this was two weeks go. For a couple of days it has had a slight hesitation when I try to start it. This morning it started fine and then i got to the corner and heard a "ticking" sound coming from the engine. I will never buy an Aveo again. I have put more money in this car than its worth. I will buy a Toyota over a Daewoo(AVEO) anytime.
