I have a 1998 Toyota Tacoma 2.4L Truck started shaking on way to work. Set Code p0304 cylinder 4 misfire. Has same coil for #1 and #4 cylinders. Maybe could use new plugs and wires. Any help would be appreciated.
Plugs & wires would be the best place to start - simple, inexpensive, and ought to be done whether it “fixes” it or not.
