service engine soon light arggggh!

hello-I recently replaced my stock factory stereo with a JVC cd/radio receiver cuz the cd player stopped working-did not replace speakers or amps. Ive got a 2003 V6 Mustang hard top. 39000 miles. 1 hour later the damn 'service engine soon' lights up-its still on after 48 hours. I tried disconnecting the battery for 15 min and reconnecting-no good. the stereo dealer swears there is nothing wrong with the stereo or installation. The car runs fine-NO problems whatsoever as far as I can tell. What can I do?? Im willing to overlook the light if I can reasonably assume there is no problem with my emissions (owners manual). should i disconnect the battery longer??

Please respond-any advice would be greatly appreciated-

if u can write to:

niko67@netzero.com

Thank you!!

I know it sounds silly but check to make sure your gas cap is on and locked. Its happened before.

Re: service engine soon light arggggh!

It is very possible that the two are unrelated.

You need to find out what code set the light.

Re: service engine soon light arggggh!

I would run down to Autozone and have them scan the code. Then post it for us.

Hello again-
found out what the problem was...I think... changed the gas cap, put
a quart of techron fuel cleaner in gas tank...oila!
no service light after about 10 miles of city driving.

Thanks to all for posting replies.

Chevron is all the tuners here say to run....I have shell in my car right now and am forced to run my 91 octane tune as a result...only chevron doesn't cause detonation here in town. Everything else is junk here.
