Engine Performance problem
1990 Mazda b2200 4 cyl Two Wheel Drive Manual 150000 miles
I have a 1990 Mazda b2200, I replaced the head gasket, (had the head surfaced, new valve seals and checked for cracks), timing belt, pullies and water pump. The truck seems to run fine on flat ground but will not pull up a hill, it wants to die. I have to ride the clutch to get it up the hill. I have cleaned the EGR valve, new plugs, distributor, and rotor button. I checked the timing and it seems right. I checked for vacuum leaks and couldn't find any. When I turn the air on the idle kicks up but idles erattically about 1200 to 1700 rpm's. Any help is greatly appreciated.
