This Blazer I have is nothing but problems lately.
It has a wierd lope at idel which I think may be a bad or sticky
The tranny is toast also I need a complete rebuilt or will put a
rebuilt on in myself.
The A/C did not work so I added a couple cans of freon to see if that
would fix it, I maybe should have brought it in but I didn't.
The A/C did start blowing cold air, as I was adding I could see and
hear the compressor kicking in, so I'm thinking it was pretty low.
Anyway since I added the R134 the idle races on startup.
Is there any connection between the two or is it just coincidence. I
don't have any codes except for the P1870, but maybe that can muck up
some other things also.
