okay car has been running perfect all summer but recently it has begun to randomly stutter while driving and feels like misfiring maybe....

ive scanned and found that it threw an EGR malfunction code and right O2 sensor low voltage along with multiple cylinder misfires....

im going to change wires and O2 sensor tommroow and changed plugs other day....



question is could a faulty EGR be causing my stuttering problems... i also read that a faulty EGR could cause engine temp to surge... and lately my car will randomly begin to reach 260 degrees in short period of time (only happened 3 times in past week and half ) i shut car off and find that if i bleed my top bleader valve on coolant line i have air in system - then car temp will drop to normal once i start driving... cant find where else im possible getting air in line from....

any ideas im getting desperate and broke
