I have a 2006 Uplander. 105k miles bought it new. Had just about every problem there is with this van. Now it has low compression 40-60# on left bank. Misfire on all cylinders and specifically #6. It will be about $2k to replace the head, etc. It was running extremely rough at idle during all this but ran fine when you drove it. I checked the plugs/wires/& compression. Had the ignition system checked, injectors, etc. All good. Now it runs smooth at all speeds, but occasionally it acts like it will stall but does not. I'm pretty sure it has seen better days but would like to know if anyone else had this problem.

Thanks!
