Check your thermostat !

I noticed when the outside temperature dropped the last few days that it was taking quite awhile for my GT to warm up. The idle speed also remained quite high. It never really did warm up properly and my gas mileage, as bad as it always is, was even worse than usual.

So, I decided to pull the thermostat and have a look...

The thermostat looked fine so I put it back in. Any other suggestions what might be wrong?

 

Just replaced the one on Shirley's car today, along with the heater core. She blew the heater core on Trans Canada this morning, so once we got the car home, did a complete overhaul on the entire cooling system, including replacing a badly bent thermostat.  Not as bad as yours, but plenty twisted.

I have been having the same issue since the temperature drop but I am not sure its relevant since my rides a hint trouble sum. Going down too the parts place too grab a 195.

I thought it looked fine?

Uri Geller is making a comeback.

The long "arms" are simply bending from water pressure pushing against them when the coolant is cold and the thermostat valve is closed.

Cheap thermostats like the one pictured above can often bend. Better ones (like the Stant SuperStat® I replaced it with) won't.

By the way, I worked out the mileage for my last tankful of gas before I replaced the bent thermostat... 13.5 mpg!

It must be your driving style. ...but in order to
drive in the city in a manner suited to better fuel
economy in a fiero, you end up holding up traffic which
is comprised of mostly peppy and efficient vehicles that
can jack rabbit start and accelerate much quicker - not
too mention the much faster pace that wreaks havoc on
fiero efficiency and don't forget all those people who
care not for fuel consumption hence the faster pace.

Ah, see, there's your problem.

And you dare scold my fuel-efficient engine swap. Pfft. lol
