'87 300D turbo engine surging
I'm new to the diesel scene, took my 300d in to have new glow plugs put in and a motor mount replaced and some other adjustments too. My mechanic let me have the car for the weekend while an air filter arrived for him to put in....I had about 45 minutes of wonderful driving and then my top speed dwindled and it begin to surge from stop signs on up to road speed....back to the mechanic the following monday, he checked out all the vacuum lines and connections in the engine compartment (some had been rearranged by PO or mechanic) well that hasn't solved it so...hopefully someone here has seen this solved and can offer the solution... thank you

Injection is over ridden with electronic fuel control.
Surges will be : Bad temp' sensor or wiring. Poor grounds. Exessive voltage from alternator. Bad ECU. Bad electronic wiring. Streched timing chain. Variation in turbo boost control. Incorrectly routed vac' hoses or loss of vac signal. Switch over valve fault. Water in fuel. Fuel supply erratic...lift pump failing. Clogged fuel filter. etc.....etc....etc .
