This is exactly the info I needed. The o2 sensors one and two have been bad for some time now. As a result MPG went to around 9 and I was getting black smoke from exhaust, from the burn off of the extra gas. Spark plugs completely clogged and burnt black. After awhile the truck just wouldn't start.
I don't know much about cars but I can turn a wrench. I start by replacing spark plugs. After a lil cussing from lack of work space I get 4, 5, and 6 flopped out. 1 is not accessible to me because I lack an extension for my ratchet, 2 and 3 I can't access because drive shaft is in the way. The truck does start at this point. Now, I decide to forget about plugs for the time being and move onto the O2 sensors.
My buddy tells me sensors are a piece of cake. Just find it on the exhaust manifold and replace it. Searching and crawling and climbing and oh yeah more cussing. I can't find the damn things. Aggravated I come inside search the site and find this post.
THANK YOU VERY MUCH BLACKTOP. Found em in 2.2 now I just need to get the burnt on rust encrusted hunks of junk off and flop em out.
I'll keep you informed on the rest of the project.
