91' 1.9L auto 216,000. I've come across this problem 3 times now. if I'm driving on the highway for more than one or two hours, the check engin light will come on (doing between 70-80 mph) and it will go off after a short period when i see that, get scared and drop it 5-10 mph.
My question is this... It's not banking the code, and I have no clue as to how to check this problem otherwise... I spent an entire day trying to pull codes and I got all clear on all three fronts each and every time (Unless it wasn't properly warmed up then i got a i think it's a 22... which simply means that it's not warm enough to give an accurate reading)
How do I get this ellusive code to reveal itself.... do I have to drop to neutral, shut it off with the light still on, and pull to the side of the highway to decipher the code?
