The car sat through a drenching rain, after starting the car it hesitates, stumbles or misses if you know what I mean.

It was fine before the rain and fine about a hour later after drying.

Obviously an electrical issue- but what? Distributor? Plug leads?
At 46k miles replace them all?

TIA

 

A 964 can have this problem if a non OM O2 sensor is used. Dont know if that would effect a 993 the same way. Send some of that rain over here to Florida!

 

Hi:

It sure sounds like you are in need of caps (rotors) and plug/coil wires. Your symptoms are the classic ones when those parts require replacement and at 46K, you are long overdue.

 

Thanks for confirming my suspicions. I'll order and install them and give it a real douching and see if that does it. If not, they were going to need replacing anyway at some point.

 

Spray a little WD40 inside the cap and on top of the cap on the wires, this should get you running again until you replace the cap and rotors.

This was std. equipment I carried in the wrecker many, many moons ago when I drove one. Florida rainstorms kept us busy but this trick usually made it a quick (temp) fix.

 

Good one- thanks.
