I think the last time I had the throttle body and EGR cleaned was over 10,000 miles ago, so I would have expected to see some smoke because I'm sure there is some carbon build up in there somewhere. Did I let the Sea Foam sit too long? Should I give it another shot, but just let it sit for the recommended five minutes?
I haven't gotten any smoke since the first treatment a couple years ago. I just added seafoam last weekend, no smoke but I could smell the fume in the exhaust. I'm considering pulling the IAC & throttle body to check for build up... My thought is that there shouldn't be much build up if the seafoam is getting fed through the intake properly.

Maybe feeding the seafoam into the brake booster line or throttle body will cause more smoke?
