Could be a few things. But here are the obvious. Check for a vacuum leak around the intake. When you put the car into drive it starts putting strain on the engine, a vacuum leak will give it too much oxygen and cause a fuel mixture issue / reading.
If nothing wrong there, you may have a bad throttle position sensor. When you put the car into drive and it starts putting strain on the engine it will pull the idle down then the sensor will adjust it automatically. Hope this helps.
Have the throttle sensor checked first and also ask your mechanic to check if the engine oil is contaminated. If the oil is contaminated they will need to clean the engine BUT Not with water! Your mechanic will advise. Good luck. had a similar problem for 2 months changed the air flow sensor, idle sensor before we found out the problem was engine contamination.
Failure of the air injection pump can cause the engine control system to go into "limp-in" or "reduced power" mode. This is because the air injection pump adds oxygen to the exhaust under certain driving conditions and will affect the oxygen sensor data, which is used to adjust your air/fuel ratio. When the air injection pump fails, the computer can no longer "trust" the oxygen sensor data because they will not be operating as expected for the driving conditions...thus, the computer switches modes to keep the engine running.
On the other hand, this only affects the PCM during the times when it should be in "closed loop". This should not have any effect on the engine during start-up because the engine is always in "open loop" during start-up.
I would be 1. Finding out why the air injection pump has failed and get it fixed, and 2. Scan your onboard computer network to see if there are any fault codes present that are either related or not related to the air injection pump. It sounds like you probably have more than one problem.
P0068 Symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of power - Engine rough idle Possible causes - Large vacuum leak - Leaking air duct system - Mass Air Flow (MAF) poor electrcial connection - Manifold Absolute Pressure (MAP) poor electrcial connection - Faulty Mass Air Flow (MAF) sensor - Faulty Manifold Absolute Pressure (MAP) sensor - TP sensor not seated properly. - Faulty Throttle Position (TP) sensor. - Dirty throttle body When is the code detected? The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings P0068 DODGE Description The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
THE INTAKE AIR TEMPERATURE SENSOR IS MOUNTED IN THE INTAKE AIR HOSE OF THE AIR CLEANER .THE INTAKE AIR TEMPERATURE SENSOR IS INTEGRATED INSIDE THE MASS AIR FLOW SENSOR.SHOULD BE NO PROBLEM REMOVE.DISCONNECT ELECTRICAL CONNECTOR,THEN REMOVE THE MOUNTING SCREWS HOLDING IT IN PLACE.THEN REMOVE IT.TAKE THE OLD INTAKE AIR TEMPERATURE SENSOR WITH YOU TO THE AUTO PARTS STORE SO THEY WILL MATCH UP AND GIVE YOU THE CORRECT SENSOR.WHEN YOU INSTALL NEW SENSOR,YOU NEED A CODE SCANNER TO ERASE CODE TO TURN OFF CHECK ENGINE LIGHT.
look 214 is not a valid code for a 1995 escort, this is an OBD1 system. here is a list of trouble codes for this year of ford no matter the model.
You should find the diagnostic connector under your hood normally by the fender on the battery side. By just using your test light and a jumper wire, it will tell you what kind of problem you got.
KEY ON ENGINE OFF (KOEO) TEST Model years 1984-1995 all models of Ford 1. Make sure engine is fully warmed. If in doubt, run engine at 2000 rpm for 2 minutes. 2. Turn ignition off and wait 10 seconds for system to shut off. Make sure A/C is off and transmission is in Park (automatic) or Neutral (manual). 3. Hook up light and jumper (or a tester if you have one). Turn key to ON (do not start engine). Read the codes.
How to do it?
Example code 23: your test light should flash 2 long consecutive flashes followed by 3 short pulses.

Normally this is due to a defective Mass Air Flow Sensor. Install a known good sensor and test drive to see if it repairs the concern. There are no test to check an Mass Air Flow Sensor. Bad ones will check good.
Ok, there are many issues here that you will need to inspect. I recommend changing the fuel filter and pump as well. this will fix the hesitation. the intake and exhaust manifold gaskets will need to be replaced as well. this will stop the backfiring.
I also recommend checking and running a teat on the PCV valve and inspect the PCV hose as well. it could have a leak or a small crack on it.
Check the air filter and change if needed. this will help with acceleration issues as well. Next, i would run a check on all plugs and the complete wire set as well. change if needed.
Inspect the injectors for leaks and lose wires. make sure they are in good condition. replace any injectors that isn't firing properly.
Ok, there are some sensors that you will need to check as well. i will list them below.
SENSOR CHECK LIST--
1. Check the O2 sensors for worn wires. 2. Check the MAFS(Mas Air Flow Sensors) Check for Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit. 3. Check the Air Cleaner Temperature Sensor. this sensor could be damaged ro have loose wires. check accordingly. 4. Check the Throttle Position Sensor. this device could be connected wrong or it may be faulty as well. replace if needed.
Be sure and inspect all the above and repair any problem spot you ruin across during your inspection.
