Rough Idle after changing spark plugs?
Have a '99 Tracker with the 1.6L and have been trying to fix her up (over 160K miles). Timing replaced 5 years ago, belts changed about 2 years ago, & just replaced radiator, thermostat, upper & lower hoses, and new spark plugs. She ran fine the day of (yesterday) but, now is running with a miss, like the timing is off. Thinking this is just an ignition coils and wire set issue, since it's the only thing not change out but, figured better ask anyways. Do I have to reset the computer after a plug change, or should I assume the worst and start looking at the timing if the coils and wires are in good shape? Thanks

'99 Tracker spark plugs and computer
I recently replaced the spark plugs on my '99 Tracker. I did not have to reset the vehicle computer. The vehicle runs fine...now. It did not run well immediately after changing the plugs. Having the #2 and #3 spark plug wires reversed will do that, I suppose. I swapped the wires and it runs great. Surprised it even started.
My point is, hopefully it's just a loose connection in your spark plug wires and NOT in the vehicle computer. Good luck.
