ok long story short
water pump failure led the car to overheat and blew a gasket. Changed the water pump, gave it new cam belt kit, new head gasket, head skimmed, all values changed and was running fine for a few weeks until it started to lose power occasionally.
It still starts BUT when it hovers at 1000 rpm in first gear the whole car shakes something awful, rev it to 2000 rpm its fine, but at 3000 rpm (still in first) it makes a metallic grinding noise then goes to cut out and die
anyone know any reasons about what the problem could be???
