Sounds like ignition wires are leaking spark.  Open the hood, stand to the side, have someone hold the car in drive with one foot onto he brake and the other giving a controlled amount of gas.  Hold the engine u at 2000 rpm, spray a mist of water onto he wires to the spark plugs.  if the symptoms occur, this confirms the faulty ignition wires

Sounds like low fuel pressure. i.e. fuel pump, fuel pressure regulator, or fuel filter.

Have 97 gmc suburban. Has a jerk to it when I'm crusein on highway and from time to time seems as if im hitting a bunch of little bumps an it boggs down. I let off gas it stops what could this b?


Could be the fuel filter. Watch the speed it happens. IE.. Ok at 50 MPH, hit 60 MPH it starts jerking. Clogged filers will give the pressure need, just not the volume of fuel need at higher speeds.

My T100 starts jerking at about 50 mph


That sounds like fuel pressure problems to me. I would try replacing the fuel filter first. If this does not work, you most likely need a fuel pump.

I think my automatic transmission modulator valve is going out because it jerks and vibrates when i accelerate anything above 50 MPH.


90 % of the time jerking or vibration is usually caused by the engine and not the transmission. The most common cause is cylinder misfiries caused by the ignition system that cause the vehicle to ****, stumble, or shudder which make it appear and feel as though the transmission is the cause. Most transmission problems will cause harsh shifts, slippage, and/or delayed engagement but rarely jerks or vibrations. I'd start by looking at the spark plugs, plug wires, and coil packs to make sure they are all ok first before going any further. The reason most of these problems are more noticable over 50 mph is that the torque converter clutch is engaged at this point and it provides a solid connection between the engine and drivetrain which makes engine misfires more noticable. Good luck, hope this helps a bit!

Sounds like your car is misfiring, if you can take your car to a parts store like pep boys or autozone and they will plug it in for free and you will get some engine codes. This will tell you EXACTLY what is going on here. If it is misfiring then your best bet is to change coils plugs and wires.
