Latest update Latest update to a sad story. I pulled the air control valve, disassembled it, clean it and cleaned it. It really was dirtier than I expected and the valve as I would spin it was gritty feeling. So I sprayed it with oil (WD-40) and carb cleaner until I thought it was ok...

Update When I replaced the plugs I researched the forums and then selected the recommended NKG's and they were identical to the ones that I took out which last 120k miles. Also I took the air control valve off the throttle body and really did wash it out good. I just didn't open up the valve...

Update on stalling I tried the propane tank trick today looking for a vacuum leak and that produced nothing. Also pulled the pcv valve again, checked for blockage and vacuum and still no results. Net effect today, I didn't solve anything. In frustration I tightened the throttle cable a bit...

Stalling updates I put the top of the line NKG plugs in it. That went easy and it ran fine for a week or two. I have replaced the throttle position sensor and it made no difference what so ever. When I cleaned the air control valve I thought I had the problem. It was dirty and required a lot...

Stalling problem I have the same problem and have tried all the remedies in this link! It's a 2000 4Runner. I had just changed the spark plugs before all this started. That went easy with no big problem and made a big difference in the performance! I had 120K miles on it. That's when the...
