Maybe the fuel pump

My 2004 Colorado 4x4 is at 91K and running better than I would have expected. It seemed to break in at 80K. Still getting 21 mpg. Haven't changed spark plugs yet. No major repairs have been needed except for the power steering pump I'm about to replace because of a squeal.

You should check the oil pressure with a mechanical gauge. If that gauge also reads low you probably have a major engine problem. If the pressure is normal on the mechanical gauge you have a problem with the electric gauge. Probably the sender, dash unit or wiring.

Try holding the button in the down position till window reaches bottom hold till it clicks a couple of times then pull the raise button up and hold it till it reaches the top and clicks a couple of times, that should reset the switch. good luck.

Find one of those radar displays that sit on the roadside and tell you how fast you're going. Most likely your GPS is the one that's off, because it has to average and estimate your speed, wheras the vehicle's speedometer should be good from the factory.

A kink in a hardline would result in a pair of them getting locked up, but not all 4. The kink allows pressure from the master cylinder through to the calipers, but won't allow it to release back to the master cylinder though in your case maybe it is allowing some pressure back which is why they aren't fully locking up. The result is that with each pump of the pedal you are locking more and more pressure into your calipers until they lock up. Opening the bleeder screw releases this pressure, then it starts all over again. So this would be the first thing to look into.

Let me know how this works out for you.

I would suspect the fuel pump or maybe even the multiplug connection into the unit?

Sounds like a bad ground at the connector.

Could be two different problems. You would need to get the computer scanned for trouble codes to proceed with the abs light.

Hi Mickey, In your owners manual there will be a section on radio settings that will show you how to do this.
