It has a 3.0 v6. It's the overhead valve one. It had a bad miss about 5 minutes after starting it. I don't know if miss is the right word. It sounds like it is stumbling. It runs fine going down the road until I come to a stop. It will stall out sometimes. It always sounds terrible when it is stopped and idling. I cleaned the air idle valve as best as I could. Now it won't idle at all. I just took off the air idle valve and am letting it soak in some carb cleaner. I really didn't think the bad idle was the air idle valve. I was just throwing thing against the wall to see what stuck. I though it was more likely the throttle position sensor. Any ideas out there.
