For any who use fuel injector cleaner, can you feel a difference? If so, how long before you start noticing results? I got some today cause my engine is idling rather rough and i have 73,XXX miles on the o.

Oh and btw they almost wouldn't sell it to me at walmart today since i don't look my age, they had to check my ID. apparently, people have died and sued walmart sniffing this shit weird, huh?

 

Another thing that could cause the rough idling is your cap and rotor. I just replaced mine at 77K and noticed a difference in idle. I did try using one of those fuel injector cleaners, but I didn't notice a difference with it.

 

I have used that shit and didn't notice much.............maybe a mental differance.

but I did install new plugs (Denso) over the weekend my car idles smooth as hell now. So consider getting new plugs.

 

how much do 4 densos run ya?

 

I got 6 from the v6 Accord group buy......i think they were $8-9 each.
