So Ive been putting it off for a year now due to all the storys I read and the lack of having the lisle tool. Well I finally went and picked up the tool and decided to get er done. BTW, the one closest to the firewall on the passenger side.....WTF Who the hell decided to put a plug there!! Any how, Ive had the truck a little over a year and have ran a bottle of techron every other tank since i got it. Warmed it up, gave it the sea foam treatment trough the brake booster hose, let it sit 20 min, then did a few WOT pulls to blow out the rest of the crap. I took out all the plugs with my 3/8 impact except the one. That would be no 3 if counting the passenger front as one and going down that side. Had to get the 1/2 impact out for that one. All came out without a problem. Was defiantly time for a change. Replace with 515s. No4 however, ( the last one by passenger firewall ) threaded in by hand, we tightened to 25lbft and then i hear the loud snap of what sounded like porcelin breaking. F Me!!! I was tired and it was 33deg so I was cold and now the engine was cold. Figured I would button it up, drive around for a bit to warm it up. I had the tuner scanning for misfires and I have none. WHEW Since it wont misfire, I wont take it apart again. My MPG went fron 10.8-11 avg hwy @65 to 13.9 hwy @65. Not too shabby I suppose. Now the true test will be the Texas run I am making at the end of this month. 1200 miles each way. Here are the old plugs

Man, glad you didnt have to use the tool.

I have to change out my plus soon. I already have the tool. Just need to hurry up and get er done.

 

Good deal! Glad they all came out

 

went ahead and changed the boots and springs today as advised on another board. wish I would have thought to remove computer and bracket from firewall the last time. Sure makes access a lot easier!!

 

You must have tiny hands if you worked around the PCM without taking it out

 

LOL I had multiple extensions and ball sockets
