well alignment was fun. took 15 minutes. From the time he got into my car till i got the keys back. $97 bucks. least i know everything passed. Then in an attempt to get better mileage. i average 25mpg. I replaced the coil pack and wires with high voltage ones and e3 plugs. Then i replaced the factory o2 sensor. (its a 91 with 130k) Still no change. Think maybe a pully is dragging? i do have a strange sound at the pully side till its warm.
