1989 camaro runs terrible after getting wet
Maybe you guys can help as I am at my wits end. When I drive my car in the rain it stumbles and hesitates terribly. I changed the pickup coil, rotor,ignition control module, cap,wires,map sensor. The car has a 305 t.b.i. , automatic trans. When I spray water on the closed hood near the base of the windshield it starts stumbling immediatly. I've checked the electrical plugs and can't find any vacuum leaks. Help !!!

Re: 1989 camaro runs terrible after getting wet
Normally , the electrical checks are done with an Ohm meter , but in your case since the car runs we know the coil has not lost continuity . In your case , we would be looking for "insulation breakdown" which would cause the coil to loose spark when wet . Take an empty windex bottle and put some water in it . With the hood open and the engine running , carefully spray a small amount of water at the coil . Does the engine stumble or quit , if so replace the coil . If not , spray the distributor a bit , if it quits (and the wires are seated properly) then the cap is defective (remember , "brand new" is NOT "proof" of perfect working components , LOTS of new stuff shows up defective these days) .....

In terms of what those connectors do, I couldn't tell you. But it's clearly stumbling because electrical components are getting wet. If you take some electrical tape and wrap the harness/connectors up good then you shouldn't have a problem.

Re: 1989 camaro runs terrible after getting wet
If the OP has found a connector that causes the engine to quit when wet , it would be best to disconnect that connector and clean out the inevitable gunk that's in there causing the connection to fail with the application of water . maybe after a good clean solid connection is established he could consider insulating the connector , but to seal it in with the water & crap that's in it now will allow the corrosion to totally finish off the connector .

Umm , Not so fast yet with the electrical tape ......

Re: 1989 camaro runs terrible after getting wet
I finally think I found the problem, after pulling the plastic inner wheel well cover loose I was able to get axcess the the wires. I was able to disconnect them from the inner car body, once I was able to see the plug I could see three wires with the coating rubbed off. I applied liquid wire coating on them , resealed the wires to the housing and reattached it to the car. My fingers are crossed and I hope this works.
