hi all my mates got a escort diesel turbo and some times there seems no power as tho the turbo isnt working. and some times it flys. hes had new glow plugs and a oil change. ive checked the turbo and it all seems fine. but ive not got a clue what could be wrong with it. some times on tick over it seems as tho its got a misfire but only a bit.

does it have an intercooler? have you checked all the boost pipes?

what age is it? My sprinter goes into safe mode at times due to loss of boost, similar to how you describe.

its a m reg escort estate. i think its 1995
he sent it to the garage but they couldnt find what was wrong so they just give it him back lol. and charged him 220 for plugs and oil

Is it a variable vane turbo? Sometimes the vane actuator arm can jam intermitently..... Would be interesting to temporarily attach a boost gauge and see what is happening....

Defniately something wrong then, the 1.8TD engine emits more power in sound energy than it sends through the crankshaft!

I would check for a sticking wastegate actuator, and for a sticking/faulty EGR valve (quite common as they get caked up with crud). You will probably find the entire induction system 'upwind' of the EGR valve is filled with something resembling black dairylea cheese due to the exhaust gasses, a lot of people bypass them.

Ive seen this problem with a golf, not sure if it the same on an escort but it was the MAF sensor. The tube like device going into the air filter. Unplug the wires going to it and see if it feels like your symptoms?
