1990 Ford Escort ProblemsProblem With Idle Air Bypass Valve May Cause Engine Performance Problems
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
Valve seats (components in the cylinder head that help seal the valve) can fall out. When this happens, it causes rough running and creates noise. Replacement of the cylinder head is commonly required to fix this problem.
The engine may overheat due to coolant loss as a result of a cracked cylinder head. In most cases the cylinder head will require replacement to correct this concern.
