No fuel was in vacuum port, the check engine did come on today when it started running bad. Autozone scanned it said it was a miss-fire on multiple cylinders. (with new plugs and wires?) I did get a fuel filter, going to install it tomorrow after work.. How do I check fuel pressure on this engine? Also the Autozone employee that scanned it said since the rough idle is throwing the engine off balance that means its an odd number cylinder??? is that correct?
