For the record, Bosch wires typically have a very short lifetime in our engines. They don't hold up to the heat very well.

I am still gonna buy the pressure meter, just to have it. I will keep everyone here posted on my progress.

Again Thakn you for the help.

now that I think about it your description of the problem is exactly the problem my car had when i bought it , and it was also plug ires that fixed it, i think you just might have fixed your problem and i dont think it will come back anytime soon (hopefully)

The alternative was Niehoff wires in a Champion box. If I have to do this again, I'll grab some nice AC Delco or something like that. I should be back from work in a few hours. Will let you all know the results.

PS. What wires are the typical ones that do stand up to it?
Mike



Edit: Well I am at work, and The car runs like brand new!! I had a chance to open it up on the highway, and went from 80Km to 140Km /hr in two blinks of an eye, no hitches, no hesitation at all.

Default wires

Thats textbook. Cars that buck under load are usually a bad wire resistance load.

AC Delco wires or Belden wires from NAPA seem to be preferred here. I have Belden'* on one car, and Belden Premiums on the other car, and both sets have given me far less grief than the 4 previous sets of Taylor wires I had before that.
