I have an 88 Ramcharger 4x4... 318 with throttle body. Lately its been having trouble with both starting and running until it is warmed up. When I try to start it, it sometimes takes it a while before it will finally fire off. Then when it does run, it bogs down pretty badly when giving it gas until it warms up. I dont know much about these throttle bodies so any ideas on what could be wrong here?
