Question Asked: ****UPDATE**** on the 95 mercury villager/nissan quest with bad knock sensor
October 09, 2012, 01:07 PM
SO I Finally bought a compression tester and did a compression tester on the van.
All but one cylinder has good compression.. one cylinder has zero compression!
I don't know how this could have happened! It's a low mileage engine..108k.. Did I cause this problem? Could a weak cylinder be the reason it had been throwing a knock sensor code??
Any suggestions what it could be? probably the rings?
Thanks in advance,
Any Advice is appreciated

It's throwing a lot of smoke... sometimes when i first start it it doesn't blow any smoke, after a while of revving the engine it starts running rough and smoking heavily.. I'm really at a loss.. only 100,000 miles I think it may have to do with the fuel injectors as i don't see a cause from anything else.. No blow by gasses from the oil filler the engine sounds good... no knocking.. would clogged injectors cause excess smoke and poor idle? Undrivable in it's current state.. i know it has got to be something simple. PLEASE HELP!
