98 jeep grand cherokee engine stumbles at idle and throughout driving range. It started suddenly whie driving down the road. Auto parts place said crankshaft sensor. Then as we were leaving, it started running just fine. 100 miles later, it started again, so I replaced the crankshaft sensor. But I still have the same problem. Pulled codes and crankshaft code isn't there anymore. The only ither code is fuel level sensor A circuit high input. Which I think has been there for years as I've always had problems with the fuel gauge. Open to ANY suggestions.

im having the same issue, except mine seems to be ok at idle. throughout the driving range (once it gets hot) it stumbles like crazy. hopefully someone knows the deal with this issue.

remove air filter cover and spray carburetor cleaner around and inside the butterfly, wipe clean and restart engine keep mouth open and spray inside while running. it helped me with same problem. good luck. my jeep is a gc 1997 and 205,000+ miles
