I bought a 1994 Honda Accord EX V Tech automatic in October 2014. The speedometer was not working when I got it. In December-ish, the gear shift wouldnt change from park and I would have to use shift lock release to neutral just to crank it. A week ago the D4 light starting flashing on my way to work. Then leaving work the light started flashing again and after several minutes the check engine like came on. Anyone have any idea what it is? Or how to figure it out?
