I need some diagrams for this car

We have no information on this vehicle. One thing to check on this though is the pcv hose used to clog with oil and not work. Also check the carb to make sure it isn't loose from theintake. You should have ported vacuum going to he distributor and unported to the vacuum for teh heater on the firewall. I may have a diagram for an earlier model bu tnot real sure and forgot when mavericks were first introduced. This could also be a carb overhaul may be needed. As there is alot of alcohol in fuel nowadays that wasn't then. It actually sounds more like that then anything else.
