What prevents a Sidekick from our years(or any car) to reach 180F?
#23
i deleted all non thermostat posts. 180F (all things that cause it not to reach 180f and hold)

We need a new topic , "why is my hot idle speeds wrong, say too fast, say 1500rpm or surging?"
sorry

check this out, this link, on topic. new.

http://www.fixkick.com/IDLE-AIR/fastfix.html

hot idle speeds fail for many reasons
1: ISC dead ( dirty or , idle switch open, or ecu in limphome, or ecu in idle up mode, or other gross errors.)
2: induction air leaks (huge list of possibles here over 15...)
3: engine power, too weak (lean fuel mix?) (a sick engine (low compression, cat melted or plugged up)
4: misfiring for any of 50 reasons (we think your does not misfire.. heard, seen or felt.)
5: egr leaking.?


in a nut shell , unless lucky or blessed with a magic touch? finding the cause takes huge effort and lots of testing using a bevy of tools, meters and a scan tool.
Luck, example,: TPS not calibrated, (and after cures this in one simple step)
not lucky example2: Gee, stuff happens on old cars... most i see are like this.
1: bad gaskets in the induction path , and hoses cracked, or clogged. up.
2: scan tool shows. close loop failing at hot idle. or idle up stuck on, or both, and 02 not working , seen one guy replace it 3 times and scans show its still dead.
later he pulls off the exhaust manifold shield and bingo , the #4 exhaust header tube is cracked, like seen on all forums x100.
and more.

that is why my page exists to help find these problems.
and fixing modern cars with no scan tool, in most cases is a hopeless endever.
after all , what the ECU sees, is what matters most....
lacking this Dang tool, is working blind.
but what if the Dang tool saved you $500 in parts, and $500 in labor or more, for the life of the car.
would not that be an INVESTMENT GRADE tool.. with pay back,,,????? and not DAMNED!
try to think about COST of owner ship. (long term) is that not what matters? most? depends on goals. keep in car yes, selling not.
what if it saves you gas , in the future.? does not that have pay back?
the tool can give you a heads up of future trouble.... (seeing random events? or 02 going dead at every other stop sign)
