Hello, I have a 93 accord ex and when the cooling fan cuts on the engines stumbles dramatically. Also, when the turn signals are operating they make a sort of high pitched squeak and the engine stumbles in accordance with the lights blinking on and off. I took the front of the car apart and cleaned up every ground. It used to be my brothers car and I replaced the engine when he blew it so i'm sure nothing was left disconnected. I don't know is this is connected or not but large amounts of the white corrosion occurs on the battery to the point where the car won't start two weeks after i last cleaned them. I have been cleaning them evey week for months. I'm pretty sure I have a vacuum leak in the manifold to head gasket. Any suggestions would be very appreciated.

 

have your battery and alternator checked

 

get some battery terminal grease and some of the washers that go under the terminal connections. Ive seen corrosion enter the wires from the battery as well, fix it asap!

 

I use nolox and the amount of corrosion that creeps on there is staggering.
