loss of power when accelerating

MikeUCFL · 03-19-2022, 09:21 PM

Since covid hit, my Z has been rarely driven. I took it out today and when starting in first gear there was a huge loss of power when trying to accelerate (even at 10% throttle), felt like I applied the brakes almost. There are no CEL's on, however I want to say the last time I filled up may be a year ago with 93 octane. I'm assuming it could be bad gas, so my thought is to use something to siphon out the gas and put some fresh 93 in, but not sure what else I should check. Possibly the fuel filter as well? Just looking for some ideas/thoughts to check.

Some more notes:
- I could rev the engine in neutral fine, seems to happen under load
- Mainly happened in 1st gear, either at low throttle or full. I could put it in 2nd or 3rd and step on it and the car seemed fine.
- The car would engine brake really badly when accelerating, and then snap back and take off.
