SeaFoam = SES light ?

My car was just dynotuned using HPTuner recently, and today I SeaFoamed it and got a SES (misfire or whatever).

If I use regular scan tool to erase codes, I won't hurt/change tune, will I?

Just reading real time data or scanning/deleting current codes won't affect the tune.

Great news. Thanks.

Just an idea...may or may not work: Try letting the car warm up and then run it hard (read WOT) a few times. Seafoam can jack w/ O2's b/c the carbon buildup released can clog/collect on the O2's and cause inaccurate readings. Some times running WOT will burn off residue. ...worked w/ my Mustang and Caprice, anyway....

Oh it's been WOT several times since then...lol.

I cleared the code, car runs great...no more SES light.

I even SeaFoamed my 97 Chevy truck. It was a much more smokey-er show since it has 157,000 miles, lol....

Thanks.
