The engine cooling fan jump on at 172.F is the fan coming on to soon?
If you don't know what temperature setting the fan sensor is you can call AutoZone and ask about the part. They will be able to tell you what temperature it's set at. I have always found if it us running cooler than it should it will decrease your gas mileage. So Yes if your thermostat setting is to low or Stuck Open it will make I run colder than it should and drop your gas mileage. I have a 92 Yukon and it calls for a 198 to 208 thermostat.
I put a 170 in because I added a performance chip. It runs great but my mileage dropped between 5 and 7 mph. Starting in the early 90s they want vehicles to run hotter. I guess that is suppose to make them burn cleaner. If you haven't changed your thermostat I would do that first. Then if it still runs cold replace the fan switch. Hope this helps you

Code 327 and336 on my saturn 1998 sl
clunch ? clutch Are those P codes ? P0327 an P0336
The knock sensor is a piezoelectric device that produces an output voltage based on mechanical engine vibration. The PCM will retard the electronic spark timing on the signal being received. The knock sensor produces an AC signal. The amplitude and signal frequency is dependent upon the knock level. During normal operation, the knock sensor system attempts to filter out all engine noise that is not caused by spark knock. The diagnostic test for DTC P0327 turns OFF all filtering during the first 20 seconds of engine run time. If a sufficient amount of noise is detected during the 20 second test, the diagnostic passes. If no noise is detected, the diagnostic fails. Since DTC P0327 is a type B code, the diagnostic must fail during 2 consecutive ignition cycles to set the DTC.
The crankshaft position (CKP) sensor defines engine position by generating an electrical pulse each time it passes by a notch of the crankshaft reluctor wheel. The PCM uses crankshaft sensor pulses for fuel delivery and spark timing.

2004 ion ,key stuck in ignition after its turned off.
try turning your steering wheel from left to right while you gently try removing the key. if that doesnt work and your car is a automatic with the shifter in the center console there is a cable running to the transmission that sometimes becomes loose causing the car not to be fully into the park position.
