i have a 96 sonoma my check engine light has been going on and off for a while now so i analyze the problem with the scanner and i got PO302 which a 2 cylinder misfire, it is intermittent the code goes on and off but the thing is it is not misfiring it has a good idel speed and has not lost any power, i had the motor rebuild because of a blown head gasket and replace the spark plugs,wires,resurfaced heads, disturber cap, new hoses and changed alot more, at first i thought it my be the o2 sensor but thats not the problem. Can any one help me i appreciate it?

misfires are caused by many things and changing stuff doesn't help cause you don't know what it does. a vacuum leak, a partially pugged fuel filter or a lean out condition will cause all of this. it's best to have a pro check it and find the cause...... you could have a an injector that doesn't work right but you relally need to get it checked out..
