Got my 92’ pickup today from the shop. I was having a code 25 for long time so I have this guy working on a valve adjustment or valve job, he said that one valve was stuck and he adjusted it.



Before was runningon 5 cylinders or less, really underpowered and rough. Drove 1 hour today on highway and hills and the difference was day and night!

Refilled tank and went to town to do few errands and the damned CEL came again,

I didn’t believe it.



I took the manual and started to read about Air Flow Meter check, took my multimeter and got bad readings so I suspect I’ll need a new one.



Anyway, I wanted to spray carb cleaner over to see if I’ve a vacuum leak and engine crank but won’t start, what the hell?! I went back to the gas tank and I heard the pump, disconnected a fuel rail andI got good pressure but no start.

I started to hear an air noise around the fuel rail and injectors and fuel pump won’t shut off on ON position so I need to turn the key to OFF so the pump stop and the noise goes away.



Any idea of what can be going on? I’m going to burn this truck soon if this code doesn’t go away 🔥🔥🔥
