Ford Escort ProblemsEngine Stalling and/or Hesitation on Acceleration due to Faulty Idle Air Bypass Valve
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.
There are reports of failures of the CCRM or Constant Control Relay Module. The CCRM has relays and switches inside that control or provide power to the engine cooling fan, AC clutch (to engage the AC compressor), fuel pump and powertrain control module (PCM). Single switches or relays can fail internally causing a number of different symptoms including no start conditions (inoperative fuel pump or PCM), engine running warm due to inoperative cooling fan, or the AC might not blow cold air.

Manual transmission...Number 2 cylinder isn't firing. Timing belt was replaced prior to the problem with the #2 cylinder. It idles horribly and dies if foot isn't on gas. It happens everytime I drive it. Doesn't run very fast even with gas petal to the floor.
It improved once when...
