I have an automatic 97 accord 2.2 vtec , recently i changed plugs and wires, changed to full synthetic and put an aftermarket filter on the stock intake. Lately it has been missing at idle and sometimes while driving it will sputter and almost cut out. At night the lights will dim and there is a noticeable loss of power. Could this be 02 or cap and rotor related? It hasn't thrown a code but it does have 170k mi on it and had the timing belt replaced around 90k I belive.
Thanks

 

Did it do this before you changed the plugs and wires or did it start just after?..you may need to go ahead and replace the cap and rotor if its never been replaced..thats what it sounds like to me..and for the lights dimming when its night..that sounds like it possibly could be an alternator...is ur battery light on?

 

There was almost what sounded like a miss but it would do it right as the fan was turning on, but it was hardly noticeable. But now im sure I hear a miss and its really obvious, the gf even heard it lol The battery light hasn't been on but it had the abs light on, twice earlier this week then it went away. I do have a big infinity amp in there though, and I wonder if I should have the alt checked first.
Also there has been a decrease in gas millage and was also thinking it could be a weak oxygen sensor?

 

turns out it was the wrong spark plug wires, I think they were heating up the trapped air and popping themselves off the plugs. I exchanged them and the problem seems to be gone.
