It is suppose to do that. When there is a power drain on the electrical system the "idle up" vacuum switch kicks on to up the idle speed to spin the alternator faster.

How do you use 4 wheel drive on a suzuki samuri

There are three driving modes: 2H, 4H and 4L, which stands for 4x2 High, 4x4 High and 4x4 Low. There is a modification that can be made on the transfer case to add a 2L (4x2 Low) mode, but that's not original.
In order to use any of the 4x4 modes you will also have to step out of the car and turn the free wheeling hubs to the "lock" or "4x4" position.

Olds 1988 delta 88 changed harmonic balancer and now odd things happen. Like sometimes when you turn on headlights the windshield wipers come on. Sometimes when idling in park the mileage odometer will...

Sounds like a ground issue. Look for any ground points around the area of the engine where you were. There are several bolts that have ground wires attached on the manifold and head areas.

Engine backfire's when you let off gas but idle's fine

Engines backfire when timing has slipped. You might need a new timing belt. \

Timing belt goes from Crankshaft on bottom of engine to Camshaft on top of engine. Both have to be synchronized to the correct timing.

Check repair manual or internet for correct timing. You'll probably have to find top dead center on first piston.
