stumbling problem

[kenny4007]

i have a 2010 sho runs perfect when cold, after getting up to operating temp, when leaving stop light under moderate to heavy acceleration will stumble and fall on it's face, if i back off the throttle and ease back into it , it will go, it is intermittent, i have changed the throttle position sensor, cleaned the throttle body, new air filter, plugs, but still having same problem

Are you getting any CEL indicators?

I believe I saw a YouTube video about draining the intercooler stopped another SHO from stumbling, just a thought.

mileage on your sho? check codes. could be a fuel pump control module issue, just started seeing those on the 2010-12s.

just replaced the fuel pump driver control module, same thing, i will try draining the inner cooler this weekend and see if that helps

the worst of it is if you drive it normal, you will never know that it has this stumbling problem i've drove it normal 300-mile, round trip and unless you get on it, it's fine, danest this i've ever seen

those years - up to '14 have had recalled fuel pump modules - thus why I bought a new one - fixed of course and keep the old in my trunk - for emergencies
