200tdi misfire

(1/5) > >>

AbyssDJ:
seems like we've still got one after changing the head gasket... although to me it doesnt seem the same. generally seems to be running smoother, still breathing a bit from filler cap but nothing you wouldnt expect at 175k or so... at least it aint smoking from it like it was doing!

anyway.... how do you actually find a misfire? as in, what do you listen for? in all honesty, i aint got a clue... its the first engine i've ever took notice of, so im kinda used to how its always sounded.

one thing i can tell for definate though, is every now and then it misses bad enough to be felt and splutters a bit as if it wants to stall... usually lower down like 2nd occasionally at the bottom of 3rd. only does it for a split second then seems to be back to normal? anyone got any ideas? as it doesnt seem constant, im reckoning a [!Expletive Deleted!] up injector

other than that i think everything seems ok... bit smokey, but the oil needs changing and apparently synthetic/semi synthetic are no good in tdi's, so gonna change to mineral and see if that helps.

Porny:
Could possibly be a sticking injector....

Just take them out and have a walk into Swadlicote  :wink:
Swadlicote Diesel are pretty good (have used them in the past) and to have the injectors checked shouldn't be more than about £5 each.

Or it could be a fault with the injector pump.... or another fueling issue :wink:  :(

extreme90:
or its getting air in cos matt never changed the copper washers when he had the injectors out  :wink:
if fuels coming out then air can get in

AbyssDJ:
