well i was having all electrical problems with my tracker like yours and stuff way worse. check your harmonic balancer, you may need new spark plugs, fuel filter, air filter, or ecm with is quite costly.i could be wrong with any of these suggestions. there is a lot of things that could be causing this. hope i might be able to help! :)

I am having a problem with the mass air flow sensor also with the arm above the carb. That is one problem. The other problem is no radio
