Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Ok, there are over 500 fault codes that will trip the check engine light. Out of these, about 250 or so are engine management related. Without knowing the fault code stored in the computer that set the check engine light, it is simply impossible to know which is stored. Unless you live in California, you can run it by any major parts store and they will scan it for the stored fault codes and give you the fault code number, which you can post here and I can go from there.
I also need to know how it idles in drive while stopped - smoothly, erratically up and down, rhythmically up and down?
Also, does it feel like an engine hesitation, or like the transmission is not responding
Is the low pitched noise a humming noise, or roaring noise, or other noise
Please remember that I am not there and therefore rely on you for as much detail possible and may need to ask for more information on occasion
Ok, P0300 is for multiple/random misfire. Do you have a fuel pressure gage, voltmeter, noid lights, engine cylinder compression tester?
