when i did it to my truck i did like the can said vaccumm line and oil and held the gas at like 2grand until the smoke cleared and the truck mis-fired like crazy then would go over 2grand but now its fine

 

I use Sea foam in all of my cars after each oil change. That would be about 4 to 5 thousand miles. Has worked well for me. I also use a good top-tier gas too. No cheap stuff..

 

Well I did the sea foam and it made a little difference dont idel as rough now but it didnt smoke much very little my plugs look a little bad gona do full tune up when I do the plenum next week

 

I don't know if maybe I am misunderstanding, but is this in a liquid form? Cause the seafoam I use is in an aerosol can and I spray it straight into the throttle body. When I first got my truck, it would idle rough and die, I replaced IAC, but seafoam is what fixed it. A couple of weeks ago, it started doing the same damn thing, I would have to hold the gas and brake down to drive it. I seafomed it again, and it runs fine(ish) now

 

The cans that I get are in a liquid. I know right beside it, is an aerosol lubricant. Hope you're not using the wrong one!~ lol
