Chek engine light on off on off on off....

I had the fuel pressure checked next (by Ford) and turns out that's good

Beware of fuel pressure tests....... too many times I see a fuel pressure guage go on and the only reading that gets taken is at idle in the bay. Fuel pressure has to be taken when the problem is occuring to actually mean much in the grand scheme of things.

A restriction in the fuel delivery or a faulty pump may deliver enough fuel to keep the pressure in spec at idle but it may fall off dramatically when the car is being driven.

Hey, I was hoping someone would tell us how to clean the o2 sensors. I'm not having the cell probem but would like to check it to avoid the problem. Thanks,

Sometimes the engine light will flash if a spark plugs ceramic piece breaks inside the boot. Also one time i had a problem with my valve body in my tranny and it would rob me of power while the light was on. Both of these problems didnt show up on an engine analysis. But my ? is if you took it somewhere to have the computer checked why didnt you just let them figure it out?
