I took the car out this morning and decided to open it up. I've had the car for about eight months and I have never taken it up to 6000 RPM and decided to this morning. It is an L72, M21 with 4.11 gears.
I was watching the tach closely since I did not want to go over 6000 RPM and just before it hit 6000 it jumped past 7000 and I assume bottomed out. I think I was in third gear. Instinctively I immediately let off the gas and then put it into neutral to take it all the way back down. Surely the engine did not pick up 1500+ RPM in that split second? It certainly did not seem to rev higher. I thought about taking it back up to 6000 slowly to see if it happened again, but I was a little skittish about it.
Is there anything mechanical that could have caused this. I have checked the accuracy of my tach up to about 4500 in the past using two different non mechanical tachs and it was right on. Thanks.
