this is new... I was driving home from work the other day and it was our first rain of the year. About 5 min into a normal drive nothing hot roddy, the engine starts making a nasty shudder that I originally thought was the tranny but I put it in neutral and it still did it. The entire car shudders while driving and shakes like its going to fall apart. almotst like theres something wrapped around the driveline and its beating up the underside. Now imagine how my rear end puckered while this happened... in the rain... a half hour from home. It took me about an hour to drive home extremely slowly and the whole night I wondered what I was going to do and how I was going to fix it or more importantly WHAT THE HELL WAS IT. but then the next morning I fired it up and it started no problem. Like a top. I babied it for the next week just incase it wasnt a fluke and then yesterday I took it through the auto car wash which has an undercarriage wash. About 10 seconds after the undercarriage was hit it did it again. I immediately shut the car off and let the wash finish. started it up and it ran like crap, then shut it off and then back on and BAM.. like new again... PLEASE HELP..... what is it... Im getting into the rain season and this is really gonna suck... Im thinking a engine management harness is shorting in the water. !!!
