I power wash my engine almost once a month when it is driven. This stumbling occurs every time after the power wash. I found what happens is water gets into the connections at the fuel injectors which causes the injectors to miss fire. To cure this, I keep a small can of WD-40 in my glove box. After a power wash, I pull each injector connection and spray the WD-40 liberally into the connector and injector. The oil removes the water thus preventing the miss fire. Plug the injector loom back in and the car will start and run with no problems. Guaranteed.

If water gets into the distributor cap, you will get a similar stumble. The WD-40, like above, can be sprayed into the cap to solve this problem. But the 944 distributor cap is sealed pretty well, so I have never had to spray WD-40 into it after a power wash.

Cool, thanks for the tip!
