Yesterday I got my 2000 GT out of storage. First I went for a 5 min drive and everything was fine but when I was driving home (157km) it worked terrible . Major power loss and if you crowed the throttle the engine would bog. I had to drive in fourth on the highway because it wouldn't maintain speed in 5th. Any bit of throttle would cause it to surge and the check engine light was on the entire time. I watched my gauges and everything there was fine. I pulled over a lot and tried to see if there was a vacuum line disconnected but found nothing. All I can think of now is maybe it's a bad plug or coil pack. Any ideas??
