1994 Ford Explorer Q&A
1994 Ford Explorer Question: Hello, I'm having OBD-1 trouble codes 172, 136, and 332.

With the engine running, gently spray the vacuum lines with a van of brake cleaner and if the engine wakes up then you have a vacuum leak. - Hal...
Hi - just curious if you ever resolved your issue. I too have a 94 explorer doing what sounds like the same things. - markratto
