96 GT throwing check engine codes P1443 P0136 P1131 after degrease and pressure wash of motor. Are any of these related and are they the result of the pressure wash or degrease solution?
First of all, i wouldn't recommend using a pressure washer to clean the engine, I like to use a very light mist from a garden hose when i do mine.
Second ... Use an air compressor or wet dry vac on blow mode to really dry those spark plug holes and see if that doesn't fix your problem.
Never use high pressure water on the engine! I wash my engine all the time but never with high pressure...
I have cleared the codes several times, several days after the wash, engine dry. They keep coming back. Which one would you tackle first so that it might be causing the others?
Take a look at the gap under the leading edge of your hood. If you ever drive in the rain, due to the hood design, water just flows into the engine bay and across the top of the engine. So its not like its going to stay dry no matter how often you clean it. For the most part all connections are water resistant but not completely water proof.even tho i wouldnt be using a pressure washer, this is a prime exampe why im scared to clean my dusty motor
