1999 WINNEBAGO CHIEFTAIN Engine And Engine Coolingenginegasoline Problems

JUNE 2005 MY WIFE AND I WERE LEAVING ROSWELL NM IN OUR 1999 WINNEBAGO MOTOR HOME WHEN WE EXPERIENCED A LOUD POPPING NOISE. I CALLED OUR ROADSIDE ASSISTANCE CARRIER AND WAS DIRECTED TO A REPAIR FACILITY A SHORT DISTANCE AWAY. AFTER LISTENING TO THE NOISE AND LOOKING UNDER THE VEHICLE THEY DETERMINED IT MUST BE AN EXHAUST MANIFOLD LEAK. THEY WERE UNABLE TO LOCATE AN EXHAUST MANIFOLD GASKET LOCALLY AND HAD TO ORDER ONE. WE LEFT THE MOTOR HOME WITH THEM AND PROCEEDED TO CARLSBAD NM IN OUR TOWED VEHICLE. UPON OUR RETURN A COUPLE DAYS LATER THE MECHANIC WAS JUST COMPLETING THE GASKET REPLACEMENT. WHEN HE FINISHED, HE STARTED THE ENGINE ONLY TO DISCOVER THE NOISE WAS STILL THERE. FURTHER INVESTIGATION REVEALED THE #4 SPARK PLUG ON THE PASSENGER SIDE HAD BLOWN OUT AND ALSO BROKE THE COIL. THEY WERE ABLE TO GET A NEW SPARK PLUG AND COIL...
