2006 honda odyssey P0172 & P0175 (System too rich)

If you getting codes for the same thing on both sides of the engine you'll need to look at the parts before the fuel and air enter the engine. You need to look at the air intake system as well as the fuel parts. I'm assuming the air filter is new and clean? Sometimes the fix is that easy.
Have you checked and cleaned the MAF sensor, (Mass Air Flow Sensor). This reads air flow levels into the engine and uses it to adjust fuel levels going to the engine.
*Note* When you clean the MAF sensor use the correct cleaning spray and DO NOT go poking around inside the main opening. The MAF assembly uses a very fine wire as part of the sensor and this is VERY easy to damage.

Where is pressure regulator located 2006 chevy avalanche

pressure regulator ???? For what , fuel system ? ABS etc .... If fuel pressure reg. inside gas tank The fuel pressure regulator is a part of the fuel sender assembly, eliminating the need for a return pipe from the engine. A returnless fuel system reduces the internal temperature of the fuel tank by not returning hot fuel from the engine to the fuel tank. Reducing the internal temperature of the fuel tank results in lower evaporative emissions.

Ran out of gas, car wouldn't crank replaced fuel pump, fuel relay, and in line fuel filter and still won't crank on 2002 chevy avalanche

still won't crank ? how's your battery ? starter ? starter solonoid ? if your engine does'nt crank , its dead ! would'nt you check the battery first ? then move on with checking the starter circuit ? seems like your putting the cart before the horse ! first of all, when you run out of gas, you need to replace the FUEL FILTER, your engine just sucked the dirt, garbage, etc., out of the tank. there's plenty of sediment in the tank, don't know how it gets there, but, you'd be surprized ! talking threw experience !!! I operate heavy equipment, its a cardinal sin to run out of fuel !!! you say you replaced the inline filter, which one, up by the engine or the main filter, under vehicle along frame ? are we talking about the same animal, PLEASE CLARIFY !

2005 chevy tahoe died while driving down highway, engine rich code?

Engine rich codes or knock sensor codes don't normally cause engines to stall while driving. May want to check fuel pressure and ignition system before chasing the fault codes.

2007 Chevy Aveo check engine light came on, code P2188, whats it mean?

P2188 System Too Rich at Idle (Bank 1) On a Chevy Aveo I have heard 2 different things that cause this code, 1. Check for any vacuum leaks in the intake , and 2. Check for oil bypass in the cylinders, Personally I don't know which is correct , But figured I could give you an area to check , Good Luck

Check Engine light comes on....

2006 uses OBDII system and you will need a OBDII scanner to check the problem. Now keep in mind that when you do a scan you will get many codes. Usually the first in line is the one that started the problem. Good luck

The temperature sensor can cause a rich mixture at the wrong time by providing a false reading of cold engine

Yes and no. The climate change may have reviled a problem you didn't know was there. I'd say the intake gaskets are bad and are sucking air. And now that you are in colder weater the gaskets shrink and **** air.
That or you have a weak fuel pump. But I'd have it checked for vaccume leaks (the intake gaskets), first.

SOURCE: idle problem on a 2006 chevy trailblazer 4.2

The code indicates an issue with the Throttle Actuator control. This is a little motor on the throttle body that opens the throttle plates at idle. That control motor may be bad and thus, causing a low idle.

I hope this helps.
