I seafoamed my hoe today. It's an 04 5.3L with 66k on it. I put half into the PCV hose, and the other half into about 4 gallons of gas. I drove it maybe 20 miles, put a full tank of 98 octane in, and now all the sudden my CPU is showing crap numbers like 8.5 mpg. At the worst, I've gotten 11.5 before the treatment. I noticed that the heads up CPU showed that only 0.1 gallons of gas had been consumed, and then no matter how far I drove the number would not go up. I have been getting 12.5-13.5 mpg with city driving lately, so I am a bit concerned.
I guess what I'm asking is, if it loosened up crap (very large smoke cloud, by the way) would it run rich at first and need to recalibrate? is there a sensor that could have gotten jacked?
thanks in advance.
