My engine was stalling when shifting into gear and when shutting down out of gear. I bought a used IAC valve and now the RPM wont go below 1800 at idle. When i put my finger over the suction hose below the IAC valve the engine slows down. I went through the idle adjustment process and it wont slow down. Did I get a bad valve?

I discovered the famous corrosion hole by the steel plug in the engine holder. I temporarily patched it with some JB Weld until i can get it properly repaired. I replaced the IAC valve I took off and the idle came back down to normal range. i guess it was a bad valve and maybe the repair of the hole in the engine holder will solve my idle problems. A water test this week will tell all.Originally posted by shallowaterhunter View PostMy engine was stalling when shifting into gear and when shutting down out of gear.
