Can anyone tell me how to know if the dod has took a crap.  Was running fine slow down going through a town when trying to accelerate got hissing noise and would not go pulled over running veryrough. When try to rev up goes to about 2000 rpms and boogs out. As messing with now won’t hardly start and dies. Sounds out of time get poop back through intake every now ans then.

Usually you get misfires if the AFM has failed, so that could be what is happening.

sounds like it might be in "Limp Mode", can you read the codes?, also a Cat Converter could have come apart, blocking the exhaust.
