I was reading on an older post that there was a certain way to seafoam a 1987 to 1991, but what about a 93??? Is there a difference at all? Thanks

I seafoamed mine by disconnecting brake booster line running to intake. Start engine, pour in 1/3 bottle slowly, stop engine, let set for around 15 minutes, start truck, go for a drive, watch everyone watch you smoke

Can't tell you where to start without the codes.... What are the KOEO and KOER codes? Also, why are you asking for help with codes in a Seafoam thread? lol

what does seafoaming do exactly?
literally the first time vie ever heard of it

Best way I can explain it is, it's like Drain-o for the engine and fuel system. You pour it in your gas tank, crank case and vacuum line(from brake booster) and it will clean up any build up or sludge in your engine

It breaks down carbon that builds up over time. But ive heard carbon helps combustion. But seafoam it great i used it and my truck idles like a dream especially after my dad and i adjusted my timing.

Start your own Thread Bev!

List your codes. Make sure you pre-warmed the engine before running either the KOEO or the KOER scans.

Then forget about the KOER's. Concentrate on the KOEO's first.
