I need some help! Started up my XJ yesterday after installing alternator(not related to issues, was running high prior) Started out about 1500 rpm and slowly climbed higher. Soon it starts to Mis-fire or backfire out of the exhaust until it finally died... seemed flooded maybe??? Any ideas on the issues?

Thanks, Mike(avocado)
 
first, have you checked for vacuum leaks, unplugged vaccuum lines ? intake leaks? second, its probably the TPS , so test the TPS as well. Did you unplug anything else when doing the alternator?
