Poor idle

Final Update??? Maybe for a while...unless I have another issue lol. I let the cab metering block and Changed the oil and drove the car in 35 degree Celsius (95 Fahrenheit) humid heat for a good 15 mins at 60 MPH. wow did it ever drive good compared to before. No oil pressure issue either! :) Good cooling of the coolant too. Next thing to do.....body work!
