Shakes or Wobbles problem
1991 Chevy S-10 6 cyl Two Wheel Drive Manual

My truck is on 2nd engine, unknown miles. And 2nd trans that I installed. I can drive normally for sometime. then out of no were the truck will start to shake like drive shaft is locking up. 1st gear is fine, 2nd ok, 3rd if u try to exccelerate fast the speed will drop and truck sound if maybe to much gas or to little. Replaced all fuel pump, new power and ground (fuel pump) etc. I ve read haynes manual front to back 10x. If u have an idea. I would greatly appreciate it. Thanx

Hello well you may have a fuel filter that is not delivering enough fuel, could be clogged or if the truck has a throttle body sensor it could be dropping out under acelleration. I hope this will be of some help to you.
