Rough idle, sudden misfire during cruising and hesitation

ive had a similar issue i swapped the lot for a known good set which cured it though i think it was perhaps just 2 or 3, but i had no way of definitely testing

Yeah, sent mail to the place I got mine and lets see if we can find a way to get another set just to see what it says.

That's OK

SO I am suspecting there could be some other injector out of specs too... We did a test running black tops before I ordered the injectors to be sure it was an injector fault. We used the p10 injector rocker shaft with the black tops and it was rather smooth from what i can remember.

Off course if you are not sure about the injectors that's the best place to start...i didnt think you were not 100% certain about them after you said you replaced them in your first post cos all the discussion was quite useless if the injectors are not OK... the fact is that IMO not enough fuel is getting into the combustion chambers for some reason hence the rough idle and low power.

Yeah I understand. I was positive on the injectors until recently as we have gone thru most possibilities. So yesterday when I was replacing the seals I started thinking it is always a possiblity as it is even with any new parts... I will try to get a adapter to fit preassure gauge to the sensor hole to get proper fuel preassure reading. If that shows ok I will not replace the regulator. Then I will try to get a set of injectors to swap and see what it says.

I had to rely on the reconditioned to be good as it costs about 100euro/each to test them here in Finland. But as mentioned, nothing can be ruled out completely...

BUT the one big symptom that appreared the other day which made me start diggin ginto this again when engine began bogging on light load on all gears and jerking/cutting off disappeared next time I went driving and has not returned. That still puzzles me what that was all about. Could the ecu go nuts just for one ride and reset for next. I dont know. But i thought it would go hand in hand with the rough idle...
