Problem with CEL that keeps coming on.
 

OK so here is the deal. I have had this check engine light that keeps poping on. It has gone off once by itself already, but it's starting to piss me off. I have already made sure the cap was sealed at least 3 clicks and it was, but after filling up and clicking it about 6 times, the light just went off when I started it back up; that was a week ago. Well driving down the road today it just poped onagain. All seems to be running fine. I did have some axle work done last week and they said it was a common code and to make sure and click the gas cap and they cleared it for free for me. Well I have also checked all vacume lines, computer connections, etc and even consulted the old chitons manual, but I can't get it to stop poping on. I live in the midwest but this is a California 4 runner, 2000 V6 SR5 model. I am at my wits and knowledge end and can't bare to take it to the dealer again, they just charge so much money. Anyone with a computer that lives near branson Missouri want to meet and help me out?!?!?! Frigin toys.

Well you might need to replace o2 censors get that checked. my car did that for the longest time and all it ment was the censors were out it cost me only 70$ to fix at least on a ford.
