what services did you actually do?

[Celicaali]

Oil change air filter oil filter spark plugs thats it and cars gone powerless

check the plugs to make sure they are gaped right. also check if you got the coilpacks in the right order. thats probably the only thing that would really mess up the car that you worked on. maybe the maf sensor too.
