Subject: Re: Sticking intake valve? by Frank on 2013/6/10 23:32:24 What a ride.Rocker arms are rockin, pushrods are going up and down smoothly soooo its not a stuck intake or exhaust valve. I started t-shooting the vacuum system and much to my surprise when I pull off a vacuum hose I do not have vacuum. I pulled the brake booster hose and there was plenty of vacuum. There is a Evap Cannister Purge Solenoid valve that sits right on top of the intake. I checked the hose coming right off of that solenoid and no vacuum. update: I removed the ECP Solenoid valve (it has an o-ring seal)and found PLENTY of vacuum. Hmmm let's see, lots of vacuum on one side of the valve and NO vacuum on the other side. Sounds defective to me. Thoughts/experiences? Also the mystery is why only #6 cylinder is coding as a misfire. Appreciate your help. |
