I had a similar problem and it turned out to be a loose hose connection to the PVC valve.
On a 1997 Ford Explorer : CHECK ENGINE is just to the left of the " C " on the engine coolant temperature gauge ( Helpfull )
Could be a restriction in the exhaust such as a catalytic converter that has had a meltdown. If the check engine light is or has illuminated, check the codes.
After the Explorer is scanned for trouble codes to diagnose and then repair the malfunction , then the check engine light can be reset
might need to check your engine soon
According to the 2000 Ford Explorer Owner Guide : No , a separate fuse for the check engine light is not listed
Well if it takes you more than 30 seconds to check it, check the engine stopped. If just after the engine run.
Check the intank fuel pump and primary pump and fuel filter also check engine timing.
The check engine light is the light shaped like an engine, or the light that states Check Engine (Soon). If this light comes on, it is time to see what the issue is with the engine.
If no codes (check engine light) or rpm fluctation first check fuel pressure
If the check engine light is flashing that means an engine cylinder misfire has been detected
If your check engine light is staying on with the engine running , a malfunction has been detected with the emission control system . Have your Explorer scanned for any trouble codes to diagnose and repair the problem
check the recalls!!
