#390 of 399 GMC Stalling, hesitation, bad Idling by passion43 Nov 11, 2009 (4:18 pm)
Well guys and girls as I said, I took my vehicle in to the dealership, come to find out it wasn't the valve seat wear that the letter speaks about. They had to replace the cam shaft actuator solenoid on the motor. They claim that I had a very bad oil build-up. It looked to them like I wasn't changing my oil, which I was but just not enough. So it caused very bad build up inside the motor. I don't want to get into very deep details about the cam shaft and what was wrong with it, but some of u would probably know. So, they gave me a price of 600.00 to fix it . This is with them flushing the motor, oil change labor parts and all that good stuff. I told them, I don't have 600 bucks, can u do something else to it that will lower the price? I said just put the part on and change the oil. They did, total cost 363.04. Still to high when u don't have the money, but I had to have it fix, before I had to replace the motor. U better believe this has tought me a lesson. Keep Your Oil Changed. So now I got to try and change my oil every 2-3 months. Man, I had tears in my eyes, when they were telling me what the cost was going to be. Do anyone no what is a good solution to put in the engine to break down oil build up? I thought about some (DAWN Dish Detergent) But, I hope this help guys.
#391 of 399 Canyon Low Power message by sean91 Nov 13, 2009 (9:47 am)
Well, regarding the "bad gas" idea, perhaps it is the way the truck's computer brain is reading on start up? Bought mine from the first-time owner at 22,000 mi this past May 2009 (he bought it in April 2006--so it was past the 3 yr warranty as I found out--but you've all said there are other longer warranties). On each of the three times it has given the Reduced Power, the gas tank has been 1/4 or slightly less AND it has been early morning when it is cooler. Once or twice with the emissions light on. Went to the gas station, filled it up, and both were off on start up with a full tank. Is it possible that it is "bad gas" in the sense that perhaps there is some humidity in the gas line--wherever the computer reads it? (Obviously I am both a car and computer neophyte.) NOw at 35,000 mi and time for another oil change. How many miles before a tune up?

Replying to: j420 (Feb 08, 2007 4:35 pm) I have had my 2006 Colorado I5 3.5L 4x4 for about a year and a half. It has got just over 88000 miles on it. I am from Canada, but i bought my truck from the states with 47000 miles. (went to school for a year, was driving back and forth everyday) Everything was all good, i loved my truck, but lately, in about the last 3 months or so they check engine light has been coming on for a few days at a time, then going out for a day or two, just to come right back on. My boyfriend works for a tow truck company/service shop and he hooked the scanner up to my truck, which revealed a random cylinder misfire code (i believe its code PO300) We did the diagnostic test, it came out fine when i was driving, no misfire, but when it is idling i has a major misfire in cyl. 3. I changed all the spark plugs, no luck, changed the plug in 3 again figuring maybe it was a bad plug.. nope! One of the mechanics at my boyfriends work told me to take the coil pack from cyl 1 and put it into 3, and switch them around. I did that, no such luck. Still misfires in 3. I have been putting mid-grade gas and occassionally injector cleaner into the truck.. it seemed to help at first, but now it doesn't. I have changed the coil pack on 3.. but nothing. I am really getting frustrated with this. I love my truck and don't want to get rid of it. But there are no recalls about this issue, and typically, my warranty JUST ended. I really do not know what to do. I cannot afford to pay 4 grand to get this fixed, but i am afraid that if it goes unsolved then it will lead to way bigger issues. Is there anyone else having this problem? Luckily, i have not had any other issues with my truck, so i am grateful for that.   Please help me!!

Replying to: tracylynn (Nov 13, 2009 1:16 pm) If you have a misfire at idle, with no engine load, I would tend to be suspicious of a vacuum leak, intake manifold leak, that sort of thing--in other words, leaking atmospheric air that is screwing up the air/fuel mixture.

Replying to: Mr_Shiftright (Nov 13, 2009 4:02 pm) i'm sorry, i know a bit about vehicles, but not enough.. How would i go about fixing this issue then? My grandpa told me to do a compression test, and then one of the guys i work for (i work in a parts store) told me that i should do a leak test.. But this doesn't tell me how to fix this. Thanks for your input Mr. Shiftright. Replies to this message: Mr_Shiftright (Nov 14, 2009 8:25 am) tracylynn (Nov 14, 2009 8:36 am)

Replying to: tracylynn (Nov 14, 2009 6:05 am) Testing for vacuum leaks might best be left to someone who knows how to do that. Basically you are looking for areas where outside air can get sucked into the engine above and beyond what it is mixing itself in the proper amounts. Mechanics use a smoke machine to test for vacuum leaks, or a propane tank, the idea being that the smoke is inhaled by the engine at a vacuum leak point, at idle,(and you can see that happening) or that the engine takes in the propane gas and starts to speed up at idle.   Too much of an air leak will screw up the idle mixture, leaning out the mixture (normally about 14 parts air to one part fuel) and causing a misfire.   So at least you know the principles now of what the problem might be.

Replying to: harveykarisma (Nov 10, 2009 4:49 pm) don't know what year your truck is. I have a 2009 Canyon which had problems with engine stalling as well. Turns out their was a recall for some engine part. Sorry I don't remember the name, but the recall can be looked up. In any case, once this part was replaced my truck now runs great.

Replying to: abby35 (Nov 24, 2009 4:34 pm) they replace the cam shaft actuator on my truck and they said I had oil build up engine that caused it to stall and sputter. so they replaced that and it's been working pretty good so far.
