hi guys, i replace the intake manifold 4 months ago, under the advise of local monroe mechanics, my car was always losing coolant and would occasionally overheat expensive job, at the time he said my heads were wet and may need to be replaced. well my low coolant light came back on withine 2 weeks of replacing manifold, and i have slowly been losing power. but the water reservoir always looks wet, and it doesnt over heat at all. it is very hesitant when first starting have to keep revving engine to keep it from stalling, the rpms drop like mad, it calms down the further a go along the road but it doesnt have any pick up and the rpms continue to drop spiractically. whats your best guess?
