Hello i jet washed my 98 wrx engine yeasterday and now the car jutters a lot like its misfireing!!...please help as im off to a show in 2 hours!!

Any suggestions to what to do??

 

Dry off round the coil pack and check if water has settled around the plug's.

If you must clean the engine bay, then, do it whilst the engine is hot, this should let most of the water evaporate!

It will probably juter and miss until the water has evaporated

 

Hello tony where the spark plugs join at the top i have dried and sprayed with wd40...it runs well for about 5-10 minutes and then again starts juttering!!

Could it be the electrics anywhere??

 

It will be water in the coil/leads, even plugs. The more you drive it, the better it should get.
