I have the same code PO446. The vehical is a 2007 Chev. Silverado LT. I have replaced the Canister which has a solinoid vavle on it (Located at the back corner of the tank). Also note it was hard to fill the tank at this time.When I tested the old one it was bad as it was stuck, and I was able to make the new one work when I tested it, prior to instalation.

99 blazer has been hard to start for awhile but will start after a few tries now wont start at all. It will turn over but sounds like it is not getting enough gas. The fuel pump is only a yr old and you can hear it clicking on and it is getting gas up to where you check the fuel pressure. it has had a recent tune up and a cold start sensor. Our neighbor use to be a mechanic and has a code machine, He said it isnt throwing any codes and that it may need a computer. I am not sure this is correct.


Check the fuel pressure, these vortec motors need 60 psi of fuel pressure to start. Anything less than 50 and the poppet valves won't open. If fuel pressure is sufficient, check the coil wire ... Chevrolet Blazer

P2176 code my wife went to start the envoy this morning and it started but when she tried to back out the envoy was very sluggish and would hardly move. The engine light came on and she just left it there for the day. When I came home I noticed the gas cap was very loose . I tightened it and drove it around the block with no apparent trouble. I checked the error code and it said P2176. Is the gas cap the problem ?


NO , gas cap not the issue here . the P2176 refers to throttle actuator control system - idle position not learned .... the test for this is a mile long , i would try clearing the code , and see if it returns , or it will reset itself if it see's 3 d ... 2004 GMC Envoy

I have a 2006 VW Passat 2.0T. My check Engine light is on and when it was scanned I got two codes 171 & 455. What does this mean? I do notice that when I fill up at the gas station, my car acts like it doesn't want to start, but when I put my foot on the gas & crank it up, it starts. Can you help me?


Engine is running lean and there is a leak in the evap system, most likely due to purge valve stuck open. This is causing the engine to flood after a fill up. This is a known problem with the 06 Passat. See post here: ... 2002 Volkswagen Passat
