Inconsistent delays between throttle and rear tire output. Prior Fuel Pump Issues
Hello all! I did some searching and some people will probably tell me this is normal, but I'm a little worried because I've already had the fuel pump replaced once on my 2009.5 G8 GT. A tremendously costly fix because of how inaccessible the fuel pump is.
I am starting to see significant delays in power output from throttle to rear tire. It seems very inconsistent and at varying speeds. Yesterday it was as simple as putting the car into gear and going and a few days ago it was when I pulled into another lane and gave her throttle to not cut off an approaching car in the next lane. I quickly went from having enough time to drop the hammer and speed up and away, to being an ******* that switches into a faster lane and goes nowhere.
We're talking about delays up to probably a second and a half. And like I said, varying times and speeds. Car drives fine, and then I experience it.
So the fuel pump was replaced between a year and two years ago. I had similar symptoms before the car finally just started having issues starting.
1. Are people experiencing multiple fuel pump failures in these vehicles? Does this sound like I might be going back down this route?
2. What else should be checked or maintenance done?
3. Would an ECU flash fix these issues? I got contact info for a local guy. I've done flashes on my motorcycles and usually see better throttle response.
Car has less than 70 k on her. She's a joyride car. No commuting, but I sometimes tow a sportbike with her.
