Well the iat is either bad or disconnected, but ordinarily that wouldn't
cause your problems, first check for spark and/or spray carb cleaner in the
air intake, this will tell you it is a fuel problem if it starts, if not and
no spark, it gets more complicated.
Hi everyone, my Grand Am has the 2.5L TBI. For a while I have noticed
at certain times, the engine speed seemed to warble, (acceleration
would not remain steady) namely at around 35 MPH in drive. Also, my
service engine soon light would come on if the engine temp is less than
More recently, it had become worse. My service light had come on more
freqeuntly--every time I stepped on the gas and the engine temp was
less than 160°F. It backfired once or twice. Finally, a couple of
days before it quit altogether, I noticed it missed a few times, and
once even tried to stall while driving. The service light was on and
the engine temp was around 110°F.
I get a code 23 -- faulty intake air temp sensor. Yesterday, I tried
to start my car, but it wouldn't. I have thought of a few
possibilities, but I wanted to see what the general consensus thinks.
Any help is appreciated.
