tune up?? any diy.?/

i'd run a full injector cleaner after about 50k miles and be done with it till 100k. u can gtet a shop-air operated fuel system cleaner from mac/matco/snapon. and you might be able to get one from autozone.

any way, pull out fuel pump relay or fuse (pref fuse if it's easy), run car till it dies. pull fuel line and find adapter for the tool. insert and install tool adapter, connect to tool. fill tool bottle up with supplied cleaner or cleaner of your choice. supply air feed to bottle. set to standard fuel pressure. most EFI engines are between 35 and 55psi. start car, LET IDLE until car dies again...remove tool, reinstall fuel lines and fuse. you're done.

is it a pain? yeah, but it works much better than those cheesy knockoff fuel system cleaners.

i guess the main key points here is fuel cleaner will definetely clean the lines but gunks has to go somewhere and thats where to fuel filter is for i guess if it gets full it need to be replace.. so do fuel line cleaner then replace fuel filter..while ur at it change ur oil and air filter...

actually, if you are gonna dump snake oil (tne up in a can, so to speak)
in yer car, to clean out fuel and deposits...

use BG-44k. it is what most shops -actually- use, and actually works.
nothing is better without taking the heads apart.

anything with the same volatile components bg-44k has will do the same.

it only works on motors that are suffering...it won't do diddly for an engine
that:

sees weekly 2 hour runs (to evaporate moisture in the oil)
and weekday daily short drives (this is abuse...normal driving)
and is fed name brand gas and synthetic oil


the KEY to engine longevity... is weekly long trips to bake out moisture
from the oil, and drain the gas tank. if this never happens then the
stuff like BG-44k can work wonders on cleaning deposits and carbon
