Mike---you should be a P car service mgr. You were right on it.

Back to normal for now and hopefully from now on..

 

Glad to hear it!

I would have never believed it myself had I not given it a try. I search about Techron on the net a fair amount before I tried it, and found almost nothing but positive feedback. btw, I do not work for Chevron.

 

Got a better theory? Seems like every 997 owner had this happen at least once and yet I've never heard of a service department that acknowledged it's a common issue. On a car that's been on the streets for almost 4 years. I've brought it up with two large Florida dealerships, both of whom responed with: "that's a first".

 

The dealer did check the alcohol content when I had my car in. It can back 0%.
