The problem could get worse if the oil reaches the manifold’s heat shield, this in turn could cause a small flame this could then spread to the spark plug covers, and once that happens it could then turn into an engine fire. |

Replying to: sstarr2484 (Jun 07, 2008 4:14 pm) As for the cylinder 3 misfires.... thus far I swapped 2 of the coils (top and middle) so I could see if the problem stayed on cylinder 3 or migrated down when the swapped coil. Everything stayed bad on 3 and didn't change. I guess I should mention I have an obd2allinone.com serial tester. So with that, I used a timing light on all wires (which were replaced a year ago along w/ spark plugs). Seemed ok w/ that. Removed the #3 wire at the coil side, sparks like crazy there, seems ok. On the spark plug side on the front of the engine I pulled it and the cover w/ the spring (I am not sure the technical term) off and there was very little if any corrosion, but wire brushed it off and cleaned off the grease on / around it too. So I guess that leads me to where I am now. Engine is still misfiring and with all the above checked would anyone think there could be something w/ the recall repair that affected it? Do you think it's the actual fuel injector itself for the 3rd cylinder? And if so, I am trying right now to look up and figure out which fuel injector is the one for the 3rd cyl. Does anyone have a picture or can you explain where to find the 3rd one? I'm by no means a pro on cars, but my grandpa is a retired mechanic so I've always worked on mine with him, so that's how I was able to do what I've done so far. I really like getting under the hood and dirty plus I am cheap and hate to pay for repairs at all. I appreciate any info some of you pros might be able to help me with! Marianne

| Well I worked on the car over the weekend with my grandpa since I was at a point where I needed a few more tools to do the job. I bought a fuel injector where I live since "back home" noone would have one in stock if I needed it. It turned out I did and now my car is running really great. I had over time lost a ton of the horse power and not realized it because the first time I jumped on the highway after I put the new FI in and hit the accelerator at a conservative rate like I normally would, it took off with a ton of boost. Nice! I did clean up the valve cover area a bit more and took a few pics, but I wish I had done so before I initially cleaned it up. Doh... We didn't take the valve cover off to look inside since it would've meant removing a lot more stuff to do so. | |

I hope someone gets something from GM, being included in the recall only means, you will get a notice to have the problem fixed, don't hold your breath expecing one cent from GM. Thankfully I had insurance that would cover "book value" of the car, at least I got something, not nearly enough to replace the car I dearly loved, but I was able to get something to drive. Good luck to all. Is there any way we can post pictures on this site of our cars? |

I have a 1999 gt, july 23, 2008 it caught fire my son was driving it . he merged on to the freeway and said, it was making weird sound and then smelt smoke . He pulled over realized there was a flame started got out of the car.... it was on fire.....called the fire department they put the fire out.... I am upset of course...I too, only had liability insurance. a friend of mine mentioned the recall for fires . so I thought I would check into it..... I thought my son did something to the car.... but I don't believe so...... how do I contact pontiac to let them know this happen to my car ..... so they can include it in the recall if they want too.....I feel like its a bad dream.... but its reality it really happen..... thank you ...any info. would be helpful....erica |

I still cant believe my car caught on fire..... I love my car... but now I think there is nothing I can do to repair it..... the alternator is burned up, box that has fuses and all important stuff in it. I dont know what the box is called.... manifold cover of course is all melted....I dont know if its worth trying to repair... or if I should just take out my alpine stereo and take of the stock wheels and say farewell.... I am so upset... this happen july 23, 2008..... I always changed the oil every 3000 miles ... my car had no problems thats why I couldnt believe this happened... can anyone give me advice? I have the gt model 3800 v 6.......looks like the fire started near the area where the alternator sits,,,, not for sure....... |
