I have an 87 YJ with 4.2L/5 speed. I just got this a couple of days ago. The guy said when you slam on the brakes it will stall. Well, I've discovered any time you decelerate hard it stalls.
The stock air filter has been replaced with an Edelbrock, and many of the vacuum hoses have been disconnected. There's no decel valve, and the hose going to that valve has been plugged.
So, could the missing decel valve have anything to do with it stalling, or do I need to look somewhere else?
Thanks for any help!!
