Vibration and Hesitation after rain.

[Chris95GST]

To make a long story short, I got caught in a lot of rain and I think my coil pack got wet. After hitting a big puddle my car started to vibrate and hesitate. I pulled over and noticed it was sparking were the spark plug wire and coil pack thing connect. After waiting a couple of minutes I was able to limp home. Now its been a couple of days and the car works fine crusiing around but once I hit over 10 PSI the car vibrates like crazy and stumbles. I just replaced and checked the spark plugs and they are fine so I was wondering if I probally need to replace my coil pack or just my spark plug wires or if something worse happend. Thanks in advance.

This same kind of thing happened to me, except worse! I had a crack in one of my plug wires, and the wire itself was exposed and grounding out on the valve cover. I replaced the plug wires and voila, all better.

Do plug wires first, then if that doesn't solve it, coil pack. Worst comes to worst you have new plug wires !
