Afternoon everyone. Ok, I have a tdi 75 totally standard. It has a rough idle. Increase revs by 100 rpm it’s smooth. Out on the road it drives fine, pulls smoothly and no misfire or hesitation right through to the redline. Back to idle speed it is not how it should be. I have changed the injector loom for a used replacement and cleaned the EGR valve. Yes, I could have two bad injector looms but unlikely. I will put a new thermostat in so it gets up to 90 on the dial, at the mo it goes to about 75-80. I changed the timing belt side engine mount from a car that was ok. Still the same. I will run some injector cleaner through the engine. Any suggestions? Haven’t scanned it as yet.
