Air leak intake ??
I have a serious hissing sound on left front of the engine (3.9 6cyl) approximately around the distributor. It is a constant hiss very loud and does not change with revs.
Have checked all pipes but cannot find it.
Have taken the air filter off held my hand over the intake and the hiss is still there. Holding my hand over the intake does not cause the engine to stall which means it is getting air froom somewhere else.
Have removed and cleaned the ISC, checked the breather pipes and all appears to be ok.
Any suggestions or ideas on what it is
