Replying to: mxer746 (Apr 20, 2007 3:39 am) Sounds like my 2000 safari. Did a complete tuneup But when the weather was wet it would misfire give me a check engine and registar a p300 error code. When dry out the problem would go away. No one could correct the problem. I did notice though that when the problem started that when it was cold and wet that the turn signal switch would also start acting strange. I noticed that the misfires and the turn signal switch problem occured at the time. I replaced the turn signal switch. All my problems went away after almost 2 years of hell when it rained or snowed.

Fuel pump fixed it. Bad connection in the tank and a build up metal filings in the motor made it pump under the specs. My distribuator was just fine after 200k and the motor runs and acts like new.
