What is your question?
1998 Buick Regal 3.8 won't start with IAC connected. After being charged for cleaning throttle body, i discovered a clogged TB screen! I cleaned EGR valve,& replaced the MAS plug. Would a faulty head gasket show trouble codes? The mas sensor , idle air sensor , oxygen up-and down flow replaced. BCM also replaced at dealer along with valve cover gasket(as per recall). I was told driving with the ias disconnected would not hurt anything! Aprox 2 miles of driving, then parked. Tried to start , I heard a loud pop and noticed a collapsed upper radiator hose. I had no white smoke up to this point! Mechanic mentioned 2 wet spark plugs, he did not suggest or mention a faulty head gasket if he did I would of tried, Barrs leaks as a precaution. I had no indication of a faulty head gasket. Or that it could of played into the ias the not functioning correctly. What would be a reasonable price to replace head gasket? Mechanics give up on my issues. I'm disabled with a limited income. PLEASE HELP ☹
