Check engine light on and glow plug light blinking?

Hello,

So if either of these sensors the MAF or coolant sensor short out it can cause the codes for the other sensor as well. Also, please check for rodent wiring damage, unplug the sensor connectors and check for corrosion or see if one of the pins have pulled out of the connectors, You can unplug the MAF sensor and see if the engine runs better, do the same with the coolant sensor, which ever one works the best, replace it. Also you can rear the values of the sensors with your scanner to see if anything is way off. Let me know wat you find. Please upload a short video in your response of the engine running so I can see.
