Greencivic94

Hi.
i just bought a 1994 honda civic with a d15z1 engine.
It drove fine until i took it to the mechanics and they played with my distributor cap. They told me.my timing was out and they put it back to place. Since then it has been spluttering, back firing feels.like its missing.
Also the tps is screwed and i cant seem to track one down.
can anybody help me!!!

id take it back to them and tell them to fix it... also check ur timing urself on the crank when tdc does the white mark on the pulley line up wit the notch on the cover and is ur cam at position "up"
