Ok, looking for input from others. My has begun to run just above the 12 o'clock position for the past 5 months. It used to be within city limits, it would run dead center at 12 o'clock, and on the freeway, it would run at around 11oclock....
I flushed the radiator and used mostly water and RedLine WaterWetter in hopes the engine would run a bit cooler. It has run the same. ...Today in the Bay Area it is hot as hell and I ran right in the middle of 12oclock and the round Warning light....
It dawned on me, that about 5 months ago, I was getting an exhaust rattle which I think was from the Secondary CAT. I drove the car around for about a week with the rattle and finally got the the muffler place and put the car on a lift....of course, once on a lift,the rattle stopped and has not come back and the muffler guy thought I was nuts and hearing things....
So,...could my slightly higher operating temp be due to a small CAT breakup, exhaust restriction? if so, what would you do? Cut the piping to remove the clog and re-weld?
TIA
