...I never really understood your hydrolock comment..:scratch:...Did you hydrolock it with the old motor or the new one???
...Thats a shame though...I would have checked the stored codes a.s.a.p. , checked the fuel rail, and probably found out it was a clogged cat, a bad pcm, or something dumb..
..You could post an ad in the classifieds I believe...Good Luck with your sale...
have you unhooked the brake booster vacum line to see if your vaccum leak coming from a torn diagram in it?
