Blaiser 1 Posted July 23 Report Share Posted July 23 Have a 1999 GS300 after heavy rains my #5 Cylinder has misfire. Windshield has been replaced almost 5 times due to roads in Pennsylvania and New Jersey. Last time I had windshield replaced technician said my car had bad rust around the window seal. More than likely the Window has been leaking for quite some time due to poor installations and poor caulking and sealant around window. Today after a heavy rain car misfiring. Popped the Hood and looked and found water on the #5 Cyliinder Wire and Spark Coil Module. Took a look and I'm thinking the Window Cowl Drain is blocked and when heavy water runs down it leaks and overflows the Cowl and leaks water into the #5 and #6 cylinders. Anyone else have this issue or fix to issue? Quote Link to post Share on other sites
