There are lots of stuff to clean injectors, throttle bodys, fuel lines, ect but is there any specific formula that is the best. Especially if your car have a hard time starting in the winter. What do you guys use/recommand?
sea foam or else we carry redline fuel system cleaner... http://www.grimmspeed.com/catalog/product_info.php?cPath=31&products_id=70
"GM Top End Cleaner" part number 1050002 is good stuff. The only additive I'd place in my tank would be Lucas.
I just Sea Foamed my OBS last night. They weren't kidding when they said it would be smokey after I restarted it! I might do it again in a couple days to really get all the gunk out. I feel like there may have been a little more pickup to her today, maybe it's just me, I don't know? I added it through the throttle body (not easy), put some in the oil, and put some in the gas tank. I also added it to my truck so it can hibernate and clean itself at the same time during the winter.
