Ok Folks, Its a long story. I'll try and be concise.
98 Dedicated Cng, 162 K .
Problem: Live Data read
02 sensors go flat lean and stay there,
Long and short fuel trim Max to compensate + 20
No response from the 02s
Frequency : Whenever it feels like it
Duration As long as it wants
Story: I can spray starting fluid into the air intake and it will idle up just fine
as long as there is spray.
Not getting Fuel. OK
Fuel Pressure stays at 75 lbs (Remember its natural gas thats normal)
Injector trims max out
Runs Fine before / Runs fine after eventually , If it wants to
