Hi, I own a 2006 Pontiac Vibe. I take extremly good care of my car and recently had a collison with a 100 lbs deer, doing about 40 mph. I hit the deer in the very front head on. My air bags failed to deploy. After shutting my car off and then starting it the check engine light popped in. So when I drove my car home and then to the collison repair place it was determined that my computer fried. Now my insurance is trying to tell me that the computer frying is not accident related. Can they do that? We check recalls and the manufacturer and there were no "known" problem areas with the Pontiac Vibes. I still owe a good 15k on my vibe. Has anyone experienced then or does anyone have any advice? Waiting tranportationless kmachleitlaborready.com

Hello: My 2005 Vibe has been exhibiting crazy idle patterns this winter. The problem occurs only when it's cold outside (freezing or below) and the engine is completely cold (first start of the day). The car starts fine, and of course idles pretty high as all Vibes do (usually around 1700 RPM or so. Everything is fine if I don't pull out and drive until the engine is fully warmed up. However, if I let the car run for a minute or two, and then pull out, the idle kicks up above 2000RPM when I push in the clutch and if I come to a stop at an intersection it will idle up and down between 1500 and 2500 RPM quickly and repeatedly. If I don't move again quickly, it will usually kick up to an even higher idle around 2100RPM. I have a stick shift, and the crazy idle is most evident when I push in the clutch to come to a stop at an intersection. Once the engine is fully warmed up, the idle returns to normal, although I have noticed that it still seems a bit more erratic then it did when the weather is warm. I have no check engine light indicating the computer has registered a problem, but it seems obvious that there must be some sort of problem with the PCM or some other component related to regulating the idle. Any ideas? I hate the thought of taking it to the dealership without having an idea of what it might be. I'm sure they'll have a difficult time recreating the problem unless I leave it sitting there overnight and then force the technician to ride with me when I start it up cold. Would a PCM reflash fix the problem, or is there something else that regulates cold weather starts that could be malfunctioning? Car runs great otherwise. I have noticed the exhaust smells "rich" (i.e. somewhat of a gas odor) when the car is exhibiting the strange idle characteristics. My gas mileage hasn't declined much though - other than what is typical because of cold temps. Appreciate any advice or insight.

Replying to: jstant1 (Jan 29, 2008 10:01 am) Have seen dirty MAF sensors do similar things like you described. Also you don't mention mileage, air filter condition etc. Have seen this on other Vibes in the shop and on my 05 W/Auto. GM seems to look the other way. Doesn't mean you don't have a problem. Make sure the MAF is clean before jumping to all sorts of conclusions and guessing. |

Replying to: cmhj2000 (Jan 30, 2008 9:57 am) I replaced the air filter a couple months ago, so that should still be good. Where is the MAF, and how do I clean it? I'm not a mechanic-type, so if it's something I need to have done in a shop, please let me know. I'd like to try that before I try the dealership. My PCM was replaced under warranty at about 35,000 miles because I was a victim of the infamous "warm-start" issue where the car would crank fine, but not start for several seconds. It would act sluggish when it did finally start. The new PCM seems to have taken care of that problem, but the idle issue has only arisen since it turned cold. The colder the temps (like this morning when it was 5 degrees with a 25 below zero windchill) the worse the problem. Anyhow, if cleaning the MAF sensor is relatively simple, I would appreciate instructions on how to do it. Thanks!
