Hey guys,
I took the Cobra I planned to buy out on a test drive today. Took off fairly quick no issues, etc. Got on the highway had the car under load in 5th gear and heard some pinging. Come to find out some wrench monkey at the car dealer put in 87 octane gas. I guess its pretty decent 87 because it didn't ping until that engine was under HEAVY load. Sooo my question is, how much pinging can an engine withstand before real damage is done? I didn't know what it was so I had stepped on it a few times (only two where I heard that) before we narrowed the problem down. Think it could have done long term damage? The engine idling seems fine although now a belt is making some noise (squeaking) but besides that the car is in top shape. Deciding whether I should get it or not.
