307 code when engine is hot with a/c running.

In that case do some testing!! Or have some testing done!!! Fuel system pressure test, inclu leak down after engine is turned off will confirm spider problem!!..... Full scan test, inclu live data review will help pinpoint other problems such as ignition or emissions issues!... Don't guess... Test! .. BTW: number 7 cylinder (PO307) is on drivers side last one back, near transmission....
