OK, so I'm not very good with the later model tbi Trucks, just simply because I haven't had to mess with them much... They're fairly trouble free... I just know the basics...
So today, my trucks started stuttering really badly... I can't accelerate very much from a dead stop before it starts jerking and stuttering.....
I had to limp it home so on the way there, I would have to build speed from 1st without putting the pedal down very hard.. Once I got up to 55 or so, if I tried to stomp it, it felt like it would kick down to 1st again, except it felt like the motor wasn't even engaged to the transmission in a way.
Immediately my first thought was the torque converter.. After limping it home. I let out the kids and family... Tried to fire it back up, it wouldn't even fire back up, after fighting it, I finally got it running again....
Pulled it around back to the work area.
Here's what I know.... Fuel is making it to the motor, it's flashing like it should in time with the motor, and accelerating like it should if I Rev it up... It will Rev up in park, all the way up to 5000, or whatever speed.
It doesn't idle worth a damn at all.
That initial stomping it from a dead stop and not wanting to take off but "slumping" made me think it was a vacuum leak immediately.
Can anyone suggest anything to help me? A little clueless.
Waiting on the motor to cool off to check spark plugs also.
