Engine Stumbles Under Full Power - ZR-1 Net Registry Forums

mgbrv8 · 08-11-2011

With the power key on, in 1st gear, at around 5k RPM, I have a stumble. However in 2nd, I don't have a stumble at all.

The gas is over a year old but I did add two cans of octane boost so I am going to run this tank out first then put fresh gas in to see if I have a fuel issue.

I just replaced the pumps and I hope that isn't the issue cause man that was hard to get back in. I also checked the pumps and checked the check valves.
