91 4Runner is idling too low, what can I do?
My RPMs are fluxing....Goes to about 200 rpms and up to 600 rpms (where it should be) Just goes up and down when I am idling....sometimes it dies...has 265k mi is it the timing or can I do anything else?

My old '91 runner did the same thing and it turns out it wasn't firing on one of the cyls. But it could be a number of things:
• Dirty injectors
• Dirty Air Filter
• Needs new plugs(fouled out plugs?)
• Dirty Throttle Body
• Timing
• Plug wires
Maybe others will throw out suggestions
