98 Mustang GT stalling on deceleration
Hey guys, I was wondering if anybody has any idea what the problem with my GT could be. I am having issues with it stalling when I am slowing down and coming to a stop. The fuel pump has just been replaced and I just replaced the IAC valve thinking that would fix it, and it is still doing it. Any ideas?
check the throttle body, make sure it is not gummed up. When was the last time the air filter was changed, stupid question i know. might be the cats also! the tune could be a little off. That is going to be a hard one. How about the throttle sensor. it could be letting it go down to much at decell.
Thanks for the response, I checked the throttle body yesterday and it was a little dirty, i actually eliminated the cats with my o/r h-pipe. And the air filter is pretty new and I just cleaned it. I will have to look into the throttle sensor though, I haven't checked that out yet.
