Hesitation on acceleration 96 suburban

Check your fuel filter for clogging and/or have fuel pump pressure checked..Am assuming it's fuel injection,if so have injectors checked/cleaned..if a carb system you may need a cleaning,carb rebuild or simply air/fuel adjustment.
Remote possibility of electrical issue,I've seen this happen as early signs of coil or coil pack going bad

My 96 suburban timing is off

I doubt your timing is off unless you have pulled your distributor. the computer controls the timing. There is a camshaft sensor in the bottom of the distributor that you will need a Tech II scanner to read and adjust the distributor setting. Normally the distributor being moved does not create driveablility issues.

Hi:) There is a brown wire with a singal black connector in the wiring harness under the brake booster that goes up behind the engine on the drivers side to the distributor area.You disconnect this wire to disengage the computer timing auto adjustment. Set the timing to 0.deg and turn off engine before reconnecting brown wire. Computer will automaticly set the timing.

Need to adjust the timing on my 94 chevy suburban 454 and it says to disconnect the wire before timing

Yours is located in the cab, on the passenger side, under the dash, right above the floor carpet. It's a single wire with a disconnect plug. It is the only single wire there. I believe it is grey, With a black plug.

I think I have a blown fuse on my 2004 Suburban

At the back of the outer seat adjuster rail is a connector. Sometimes the conn comes apart or wires break or wires get shorted and trip the seat circuit breaker or fuse. This will happen on either side of seat. Also make sure nothing was stashed under the seat to cause wires getting caught & pulled out.
