*SLOT MACHING RINGING* Did you tell the tech about this one off Techron treatment? Any response?
Sounds like the additive migh have done its job and the engine wasn't ready for it.
Look into an extended warranty and then do a total diagnostic. Sounds like you have either a big problem brewing that may be hard to pin point (good for the pre-warranty inspection) or roll the dice and potentially take a big hit if this Techron theory is off.

I didn't mention the techron...maybe I should've. I didn't want to give them any reason to say I screwed up the engine. Besides, isn't this stuff harmless and added to all Chevron gas? Could techron make the car knock, especially if it was mixed in properly?

I have used Techron at least twice this year. No problems.

You probably did the right thing but since you said your car was out of warranty I figured it was a safe to ask. I would be curious to hear what they would say about the additive shaking loose a deposit that may have briefly stalled your engine. Question is, does the engine expel the deposits?, in other words did the tech notice dirty smoke after the car was parked for a few days? or are deposits still in there?

No no, the car is still IN warranty because I got an extended warranty until 2010. I did not notice any smoke and the tech didn't mention any smoke either.

I use Techron Chevron gas with no problems and use a fuel injector/carb. cleaner with every oil change. Never had any bad effects.

Ok, I got home and hooked up a diagnostic reader to my boxster and 3 codes came up.


P0301 Misfire, Cylinder 1, Damaging to Catalytic Converter

P0341 Camshaft Position Sensor 1 - Signal Implausible, Short to Ground, Short to B+

P1531 Camshaft Adjustment, Bank 1

Anyone have any history with either. Going to have it towed tomorrow while I'm off.
