So recently I have replaced the Cat, Flex, DPFE, PCV Tubing. I have an 02 Zetec with A/T. I recently started stalling in heavy traffic at opperating temperature. I have found a lot of positive pressure in the valve cover. I am running a K&N Typhoon intake and when I disconnect the hose between the valve cover and intake tube I don't stall. She runs perfect. When I remove the oil cap you can feel the air blowing out. What would be causing this?
After extensive reading here and on my local Canadian forum I have rigged up a filter on the tube I have between the intake and valve cover. Tomorrow will be the big test in my morning commute.
Anyone have any input on this?
