I have a ford escape 2002 v6 it stumbles and gives me code p0302, I changed cops, sparq plugs the most basic I tested egr valve vacum, when I put vacumm it idles an almost stalls. But when I hold the vacum it does not hold it, it stumbles with the hose on or off I tested all egr components but cabt find the culprit, I know for sure theres a vacum leak, when its cold it idles a little rough, but when weather is warm it idles perfect and stumbles less.
Model: ford escape
What have you tried so far: Egr component testing vacum and circuit
