You can buy a diagnostic computer for your car but try this first
with car off, turn key on (but not starting car) in this succession.
on - off - on - off - on then leave the key in the on position (again, without starting), and it "may" begin to blink the engine dash lights in a series (example): flash, flash (pause), flash, flash, flash, (this would be 23 ...and so on. Your owners manual should tell you what the codes mean. If not an auto parts store probably could.
Hope this helps and saves you some money.

    P.S. I think 12 indicates the end of the coding sequence (flash) pause (flash, flash).

    good luck

I have a 2008 Saturn Aura. Its throwing 2 codes, $7EA and $7E8. 2 mechanics in my home have never seen these codes.

Honestly, no idea acout Saturn Aura's error codes.
But, looks to me that those two mechanics you called are not really very efficient,
Guess you should look for a GOOD mechanical service and get your car's computer scanned by someone who really knows how to use a scanner,

Replaced MAP Sensor, now I have a misfire

My bet is on a bad Oxygen sensor for the random misfire. Don't forget there are upstream and downstream Oxygen sensors. Check the Rock Auto site for prices. It looks like you can replace both for about $60.

Hi, the word service on my dashboard is alway lit up, what does it mean?? If there is an issue could I fix it myself or do I need get a mechanic to fix it? Please help.

Take it to a mechanic and get them to run the diagnostic machine on it. They will plug a computer into your car's computer and it will give them an error code. This will then tell them what the problem is. Usually costs around $75

What does "Service Vehicle" mean and how do you turn this notice off when serviced?

That means your car has detected one or more error codes. A mechanic can use a device to check error codes on vehicles to determine the problem(s) associated with them. Some businesses will do the check for free (e.g.;Autozone). The device the mechanic uses can also clear the error codes from your car's computer,which will turn off the 'service vehicle' light until another error code is detected.

Take your car to a reputable mechanic or to a local autoparts store. They will use their scanner to obtain the error code your car's computer is putting out. The code will give you the 1st step in resolving the issue.

Check engine light on 2000 Firebird stays on.

OK, let me explain something, THAT LIGHT IS NOT A DECORATION, it comes on when something on your engine has failed, take it in and get a mechanic to read the trouble code out of the computer, it will tell you what has failed and you can go from there. chances are you have fried a sensor and need to replace it, sensors can cost from $50-$250 usually + labour.

I have a 96 stratus the engine light is on.

Your most likely have an electrical problem behind the dash, but to be safe I would suggest going to a mechanic and have him/her scan the computer for any error codes, that will give you your definite answer. Once a code has been found, your fixing will have a direction.
