Is it safe to use fuel injector cleaner in our cars? I've heard that it can mess the engine up so I want to make sure... If it is safe, what kind should I use? I have a 99 v6. Thanks for the help guys

 

might want to use some sea foam. i use it in both the 04 gt and the 93 notch. works great

 

Can I add all of the seafoam to my gas tank or should I use the vacuum (I found the post on seafoam however it's being done on an 8) If I need to use the vacuum where is it located on the 6... Sorry if i'm being annoying about this, i've just never done anything like this before.

 

i use it in the pcv system. just let the engine suck it up(i use half a can at a time) and then turn the car off. let it sit for 5-10 min. start it up and watch the smoke show lol

 

wait so u just let it get sucked up by the intake?

 

yea. i put some paper in the throttle so the rpm is at about 1300-1400. then pull the pcv hose from the intake. spray in in there. the car will stumble and run rough. do a little at a time so you dont hydrolock the engine. when you get about half a can in it turn it off. wait 5-10 min. then start it back up.

 

i've used fuel injector cleaner for mine and so far no problems, i've nvr heard of it messin' up our cars...anyone have any first hand experience on this?? and umm wtf is seafoam? i should prolly know that one...also since this is labeled "injectors" anyone know what our stock v6 injectors are? and if i wanted to upgrade, what lb. injector should i go to?, and i plan on having the maf reflashed and a 70mm tb...thx guys!

 

I put in a bottle of STP fuel injector cleaner every other tank
