Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. If you can explain what type of problem you are having and post back with complete details I will see if I can help you with this. Your cooling fan is designed to turn on right at 215 degrees. Can you monitor the coolant temp on your scan tool and see if that is the case?
If you not loosing coolant and the fans are running as they should you may not have a heating problem. If you give me the actual fault codes your getting I will have a look at that for you.
The P0300 indicates the PCM has detected a random misfire and if you have access to a scan tool that can read the data stream you can look at the misfire count and determine which cylinder it is. The common cause for the P0102 to set in most cases is usually a failing MAF . Start with making sure its clean and the air intake hose is sealing and tight. If so then run the test steps in the link below to check it before you consider replacing it.https://dl.dropboxusercontent.com/u/104923897/P0102%20Jul%2028.pdf
It could cause the misfire and could affect engine temp if you somehow have a vacuum leak causing the engine to run to lean. In most cases if that is the case you would also see a lean code.
The fuel gauge should have no affect no engine performance as long as you have fuel in the tank.
Well if its reading the Air/fuel mixture then you may be lean but like I said, the computer will usually pick it up and set a lean code.
Okay, Im here all day if needed.
