2001 Intrepid Engine or Sensor Problem??

Hi,

I have a 2001 Intrepid that seems to be doing something strange and I
was wondering if anyone might know what the problem could be.

My car runs fine until the engine temperature hit right above the
second line of the engine temperature gauge. It's almost like
clockwork.... the engine begins to stumble as if I put bad gas in the
tank, it idles up and down for no reason while driving and while
sitting still, it sometimes even stalls out.

If I let me the car cool down it returns to normal but as soon as it
gets back to the magic spot on the tempature gauge, the cycle
continues.

The funny and interesting thing about this problem is that it seemed
to start happening right after I took it in for 60k service, this car
is strictly a highway car, back and forth to work 40 miles each way,
each day. I would hate to think it was dealer inflicted, but, I'll be
damned it I'll take it back to the dealer after spending 1k in service
charges just a couple of weeks previous.

Anyone ever experience this or know of anyone who has. Are these
signs of a faulty thermostat?

Thanks

 

take it bac in and have them pull codes there should be some from what you
describe

 

Darrick,

In the meantime before you take it back to the dealer, try this. With
your engine off, try turning your key ON-OFF-ON-OFF-ON (without starting
the engine) in sequence. Watch the odometer display. It is very possible
that it could display codes, followed by "done". Any codes will begin
with a P. If you get any, please post them here. Unfortunately codes
may still be set, even if this process does not display them. (If this
method cannot provide any codes, the display will just revert to the
odometer. )
