A couple months ago I bought a complete engine as a backup 22RE for $750. I also have the igniter and a couple ecus. I lucked out and found a TPS sensor almost new at the junkyard. TPS is a real problem on these engines because a lot of mechanics will spray carb cleaner on the throttle body interior and it leaks right into the TPS and destroys the contacts. Another thing I carry is old and sometimes new fan and AC belts and the previous sets of hoses I've replaced I carry the old ones just in case unless they're destroyed.?
