Just gave the 4runner a tune up consisting of plug&wires, Distributor cap&rotor, new K&N air filter, three new belts, oil change W/filter, and fuel filter change. It ran great for about 2 weeks and then starting running really ruff while driving or in gear. If I put it in park or neutral and it will idle fine, but when I put it in drive it starts to shake a little and when you drive it's pretty bad. Just don't know where to start or what to look at. thanks for your time
