    the check engine light does not come on. It misses bad, then runs good. Sometimes it will die. It seems to run worse when you put it in gear. Then again it will run crappy (like an old carburetor that has trash in it) then run normal

01 GMC 1500 v8 z71 ...missing & not shifting on


The transmission has been electronically controlled for several years.
The miss could cause the knock sensor to set a code, but the sensor will not cause the miss. The knock sensor signals the computer and the computer tries to cut back on ignition timing to stop the knock. The sensor can set a code if it is a spark knock or something mechanical.

I have a 1996 silverado with the 5.7l vortec engine. My Service engine soon light came on today so i took my truck to advance. They read a code PO172-System running rich (bank 1) and my exhaust has a...


the code indicates a bank 1problem.so anything that is common between both sides of the motor will not set this code,if anything it would set a different code and show a common code for both sides of the motor,vacuum leak would not be the problem as it would also affect the way the motor runs,bad /dirty maf sensor again affects both sides and a code difference,bad coolant again affects both sides and different code,an 02 sensor can show which side the problem is and could cause the setting code.bad spark plugs can also cause this code, an injector one or more for this side can cause this,bad fuel pressure regulator will affect both sides again.so I would check spark plugs, check the 02 sensor for proper voltage readings on the left side of the motor(driver`s side),it`s uncommon for injectors on one side to only go bad and not injectors on both sides.if the plugs are okay and don`t need changing you may need to check for tune-up items such as plug wires.it sounds like the motor is not burning the fuel properly giving the rich running code

2006 5.3ltr chevy silverado z71 p0455 andp0449


These codes are for the evaporative emission system.The 455 is the vent solenoid.The 455 is a large leak in the evap.system.The vent solenoid I would replace because they go bad and will not work because they are under the vehicle in the rear of the truck.There is a bulletin for these and the vent valve is installed in another spot.The number for the bulletin is 02-06-04-037E.You should also look for a broken or loose hose or pipe that might have came off.Specially if you ran over something.If none found it could just be the vent solenoid stuck in the venting position.Good luck.

I have a 2000 chevy silverado Z71. The drl quit


There is a light sensor that tells the truck if it is night or day on the dash. Make sure that is it not covered up. If is is not then you may have a bad sensor. It sounds like the sensor is telling the truck that it is night every time the truck is running.

Start the tuck with the park brake on to see if the light come on when it starts. If they do you have a bad relay if not it is most likely that sensor on the dash.

O2 sensor problem


I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.
