2003 156 2.4 JTD - poor running issue.
After fitting new oil filter, fuel filter, new oil and a new EGR valve (removed old EGR and blanking plate with mastic) car run really badly. It felt like fuel surge from a tank low on fuel.
After asking on here it was suggested to try a new MAF, after unplugging old MAF the car ran smoother, but no power as in some limp mode, so thought this was the issue. New Bosch part purchased and fitted.
Can anyone help please???
What could be wrong that the blanking plate could of been hiding/fixing/masking?
Prior to trying to treat the car with love she ran ok, the warning light would come on when you got a lick on in the higher gears, but would go out again.
Pointers, help advice all gratefully received.
