When the engine warms up at idle the exhaust cam is going to -26 degrees and causing it to loose vacumn and stall. I can unplug the solenoid and per evoscan it will sit around minus 6-8 degrees and stay there. with it plugged in after warming up it will drop to around 26. i just had the engine apart and Know the cams did not have this problem a few months ago. I swapped the solenoid with no change and going to try the cam sensor to night just because i have one. I was wondering if any one else has had a similar problem and if so how did they fix it? I am curious if there is anyway to clean the cam gear passages with out pulling the cams incase maybe some debris got in it. There was no filter for the mivec control which the screen is now readded to it but it did not start the problem till recently.
