Why does my G Wag keep dying?
My 88 Grand Wagoneer keeps dying on me. When I'm idling or coming to a stop it'll just decide to shut off. I've checked timing spark plugs, fuel filter, and thats all ok. I've heard it could be an oxygen sensor, or something w/ the distributor. Are there any Jeep Jeniuses out there that know what's wrong?
idle has been adjusted numerous times. vacuum leaks have been checked found and fixed, I guess something could be bad w/ fuel line, but I use good gas. There isn't really a pattern to when it decides to stall. I guess it does it a little more when it's warmed up, and when I brake harder
Could be your brake booster. If there is a tear in the diaphragm, it could cause this, especially when you hit the breaks. Plug the hose to the brake booster and try driving it when warm this way. Give yourself plenty of time to stop though! You may want to do this on an empty road.
