Piston Slap: Focusing on Turbo 93 Octane Tunes?
Thanks for the recent advice on winter tires & wheels for my new Focus ST. I took delivery of the car two weeks ago and I’m having a blast. The first thing I did when I got it home was take Bark M’s advice and sign up for the Octane Academy.
So here’s another question: What’s your take on fuel octane and the ST?

Long time listener, first time caller. The patient: a 2005 Saturn Relay FWD3 with 151K miles, GM 3.5L V6 and 4-speed automatic. I am the fifth owner and this is our grocery getter and general abuse vehicle. I’m the longest owner – 4 years and about 55K of those 151K miles have been in my garage. I can’t comment on how well it was cared for from year 2 to year 6, but I have done everything by the book since 96K miles.
The Saturn developed a rough idle of sorts about a year ago. I swapped out the spark plugs, changed the fuel filter, and flushed the fuel injection. The car continues to idle rough. No CEL and no CEL history.
Toyota Recall Includes Computer Reflash, Trimming Gas Pedals
We’ve gotten hold of documents relating to that other Toyota recall, the one from last fall regarding pedal interference with floor mats. Tying the floor mats to the seats was the short term fix, but now Toyota has the permanent solution. This includes cars with the Denso pedal that is not part of the sticky-pedal recall. The main features: cutting off the bottom of the pedal to make it shorter (yes, with a reciprocating saw) reworking the sound-deadening and carpet near the pedal, and most important, from our point of view, a reflash of the computer to give braking priority over throttle inputs.
