2003 gmc envoy
My envoy a couple weeks ago started chugging
and sounding like it was going to die when idoling
but goes no problem and stopped chugging when I
excelerated. It also doesn’t seem to want to blow
any heat from the front vents and mostly just cold
from the rear which still seems to blow a full force, if
I hit the highway as I excelerate my heat eventually
turns on but even with it turned up all the way it
barely blows at half the force it usually does but
then it sounds like the motor for the fan won’t shut
off when I shut my car off and it’s actually killed my
battery a couple times now. The chugging stopped
a couple days ago (still having the heat issues) but
now I’m noticing that I’m going through an absurd
amount of gas, like a quarter tank to go to the store
and back which is about 5 km each way and there’s
a strong gasoline smell whenever I get out of my
vehicle. Nothing has happened to my vehicle (I’m
the only one that drives it) and I haven’t had to have
any repairs done for this all to come about so
abruptly....... anyone have any ideas what could be
causing all this?
