Cylinder 3 misfires in 99 chevy suburban


try moving your fuel injector , switch with another one and re assemble, clear codes and see if the misfire moves with the injector. If the miss fire moves with the injector then replace the injector with a new one. Or if you havnt tried already fuel injector cleaner may work.
remember after you clear the codes you have to drive it for a couple days before it gets e tested. obd2 systems have to be ready or it will fail etest.

Are there two oxygen sensors on a chevy suburban or four its a wheel drive with a v-8 our


Hi, if the suburban is 1996, or newer, you will have 4 O2 sensors. The sensor mounted before the catalytic converter, is sensor 1, and the sensor after the cat, sensor 2. These can also be referred to as pre, or post. The driver, or left side of the engine, is bank 1, as the passenger, or right hand is bank 2. years prior to this, use 1 O2 sensor. Good luck...Coop

1999 Chevy Suburban 1500 stuck in 4 wheel drive.


Check the wire harness on the transfer case to make sure it's still plugged in. Check the selector switch in the dash. Check the hub sensor wire harnesses on the front wheels.
Check for error codes through OBD-II connector under the dash.
Good luck.
