Sea Foam cleaning, now engine misfires

[Ed Barlow]

I did the Sea Foam cleaning but did not run the truck enough after the cleaner was added.

Maybe I put two much in too, at any rate, the engine is rough and misfires.

I had good luck before with the cleaning before, just screwed this one up. What is the best recovery for this, I am getting a CEL with 301, 303, 305, 306, 316 and sometimes 171 codes

NOT ALL AT THE SAME TIME.

Should I clean the PCV, intake, IAC and/or what are my options?

The truck reacts like its a spark, fuel issue, but this was not touched

Did you add to much seafoam, to quik, did you hydrolock your engine?

May need to drive the thing, when the shop guys added too much to smaller engine cars we had to drive them to clear things..... you could have a puddle in the intake or something weir din a vacuum line and it is still in the motor..

TOO MUCH! When I did mine I used the whole can, sucked it into the brake booster hose.

You say you had good luck with it before. I wouldnt think it would be needed only every 60k miles. If it did break loose any large peices of carbon though. Might have damaged some of the sparkplugs.

better now, just a 303 or cylinder 3, I have to fiqure out which one that really is, I did a coil upgrade and needed to swap the wires.

The ECU says three, but it might be a different actual cyclinder.

I want to clean #3 plug

"not gonna do it", #3 ouch !! I will follow "Dr. Z's" advice.
