also when i put my car in park the rpms go up gradually to like maybe 2.5 - 3 and wheni turn my car offf when its way up there it knocks.

My 89 SR5 is not fuel injected, it has a carburetor. Try adding some fuel additive to your gas. It will clean out everything, and remove any water in the system. I like the Berryman's additive best, a second choice gumout. I prefer the Berryman's that sells in a metal cylindrical can.
