2004 Infiniti I35 Q&A

2004 Infiniti I35 Question: Low to mid acceleration, I hear pinging.I use high octane 91 Shell gas.

I live at 7000 feet. What should I do? I should be able to use 87 octane at this altitude, but that makes it worse. I have a 2001 Infiniti I30 T and it never has that problem and I use 87 Octane in it. Thanks, -
Answer 1
PINGING IS CAUSED BY HIGH ENG TEMP, IS IT RUNNING HOT OR IS TIMING OFF? -
