I own a 2003 Honda Civic LX 1.7 Automatic. I recently took the car in for "work". I had the oil changed, all the air filters changed, brakes/rotors. Now, two weeks later I was driving down the interstate and the car died. I tried to crank it back up it last a few seconds then died again. I changed the fuel pump relay now the car will start but it's awful. It's idling wrong and drives horrible a 10 mile trip ate almost 1/4 of gas (I get 32 miles a gallon). My check engine light came on and it's throwing pressure manifold sensor p1298 electric circuit high input p1129 idle control system p0505.
I have no idea what to do from here. Suggestions?

 

First check under-dash Fuse No. 17 (15A) and Fuse No. 4 (10A).
