HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Ok, when they burn out that quickly and getting that hot, the engine is either running super lean or super rich, so we need to start with fuel pressure check, vacuum or intake leaks, O2 sensor readings, and fuel trim readings to see if it is rich or lean condition and go from there

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
