I have a 1998 Tracker w/ 1.6 engine, auto, 4wd, w/120,000 miles on it. Ran great for last 13 yrs. but getting lazy fast. I replaced wires, plugs, dist. and rotor with no improvement at all. Plugs were burning nice and white although gapped a little big. Anyone have any suggestions where to start? I also cleaned the emission ports.

 

regap the plugs and run a compression test on it ! if the plugs are gapped too wide it will lose power !
