new plugs

well after seeing how much of a pain in the *** it would be to replace em myself, my dad knows a guy who does tune ups with new spark plugs for $75 (and thats the 8cyl price lol)

truck seems a little bit peppier ... ill let you guys know if my gas miles go up cause thats what im hoping for ... i didnt get to see the old ones so im not sure how fouled they may have been

already did it and the engine is dual spark ... so thats 8 plugs .... and without a special tool to get to the drivers side rear one you have to take the intake manifold off

i got at all mine with out removing the Mani. one thing I did was unbolt the a/c and move it some to make things roomier, but it's not impossible to change them all without takeing anything else off if you've got the patience. and a long peice of fuel hose makes getting them started alot easier.

i got all mine replaced without taking off the intake manifold or the AC unit. it does take alot of patience and busted knuckles but i got it done. not in one hour though it took me around 3 hours to complete
