I have a 93 integra ls motor in my 96 hatch and i just changed the spark plugs, wires, a new distributor, seafoamed the car. It already had a check engine light when i got the car i just picked it up yesterday. The guy told me it was for the o2 sensor and idle air control. It was running fine till i did the tune up. Then after that, i drove it and it was missing, but sometimes it doesnt do it at all and runs fine. Checked the check engine light code this afternoon and i got the o2 sensor, idle air control, and it said every cylinder had misfire. What could it be?
Anyone?

 

Something you did with the dizzy/wires. Make sure the rotor is screwed on all the way, make sure the wires are pushed on all the way.
