    1997 2-Door - aftermarket rear sway bar

    My 4 door Yukon's OE rear bar swept upward. The previous owner installed it upside down for some reason? It's there for reason, what's stopping you from flipping it over the right way? The cost of new sway links? If you do decide to remove it, kindly PM me and I'll take it off your hands in a...

    93 5.7 cat delete o2 sensor light

    The non fouler is for downstream sensors, not the single upstream in a TBI. O.P. has a '93 OBD1 vehicle... (per title and post #1) The use of the non fouler is to sample less of the gasses. And the upstream O2 needs as much flow as possible. If you extract the sensor from the uncatalyzed...

    93 5.7 cat delete o2 sensor light

    You're wrong. The Upstream O2 sensor has no idea that the catalyst is present or functional. You need to correctly diagnose the code instead of loading up the parts cannon.

    I've got a set of 1.5" hub centric spacers if you're interested. They cost me $81 new, I've never used them. (went with a pair of 2" on my 2500) $70 plus shipping and they're yours.

    Remote locks on an 89?

    When I bought my Yukon it had power locks and the OE key fobs were long gone missing. I had a remote starter installed and the installer hooked it up to the doors. There's a harness under the dash he tapped into. It was as simple as following a wiring schematic.

    Turn signal/Hazard Issue. Help greatly appreciated!

    Are you referring to the indicators? Like you press the brake pedal and power backfeeds to the instrument cluster, illuminating the green indicators on your dash? Or are you saying pressing the brakes lights up the front turn signal bulbs? Either of those would indicate a bad ground. That...

    Turn signal/Hazard Issue. Help greatly appreciated!

    Can you elaborate on this? How would the hazard lights flash if the switch is off? Are you saying that the brake lights flash when you depress the brake pedal? If you do activate the hazards, they operate the same bulb filiment as the brakes and will stop flashing when you step on the brake.
