Beeping under dash. Only once in a while while driving. Searching threads and sounds like it might have to do with airbag or somethng. If I need to unplug it where's it at and is that ok? Beeps are five then quit then five again.

Had it for a week now and first few days the check enging light didn't come on. I pulled some vacume lines to check for vacume and now it comes on but not when I start it just after if runs for a couple minutes. Could pulling these lines when it was running make the check engine light start coming on? And should I reset the computer by removing the batterie cable and is this how you reset the computer?

ABS light blinks but only with semi hard pressure on peddle after start up. If I start it and gently depress the peddle at slow speed to stop I can prevent it from coming on.

Other than this it runs perfect and brakes good but there is a weird noise when breaking when I am turning. Kinda like a brrrrrrrrr noise but stops great. Noise is coming from front wheels.

Thanks for you help
