Need HELP!!!!!!
Have a 95 silverado 2wd. Truck takes off real luggish when in drive but i drop it to first and manually shift it fine. Ive been told it could be PCM or solenoids. Also the tach or speedo dont work. Tried to run the codes by grounding the a and b on the plug in but the service engine light wont even blink. Really need some HELP!!!!
