Today, I have been mostly replacing the PCV, I was pretty careful and fairly certain that all was well, the old system was holed in all kinds of places, but after all the effort I am rewarded with a misfire. I'm pretty certain that I've connected all the sensors. Any ideas? Raining now so will leave it for the morning. Cheers bonnietiler
What car do you have?
850R. Working REALLY well before I did the work...It feels like a sensor or a vacuum pipe but I can't find one
Did you tighten the inlet manifold up properly?. if it's drawing in unmetered air then that would make it run bad and feel like a miss.
Or the hoses to ICV they are pretty weak if old
Have to hang head in shame and sit in corner and play with bricks and sharpen my wax crayons.... On the inlet the right side (looking from front) there is a little pressed steel bracket to hold the main PCV pipe, I think it is recommended practice not to have this between the inlet and the engine...hmmm Leads to misfire and bad running...ah well all fixed now and running sweetly. The old PCV was cracked and rotten in at least 3 places so must be better now. Thanks for the help, all much appreciated. Bonnietiler
Doh!!, glad it was an easy fix at least.
