hey guys, im a newbe here and im just looking for some troubleshooting advice. I just got a 4 cylinder five speed and those damn lights are coming on. Maint. req and check engine. My friend is a pretty up to date mechanic and he is perplexed as i am to the computer read out. the Diagnostic code read out that there was a leak in the vacume lines but i here no hiss and my car runs relatively trouble free. no sign of a break down is evident. the maintenace req light is now staying on now and not just blinking. i have had the car for three months and it is pushing 150 k miles. is the maintenance required light, odometer tripped and what do i need to maintain?i appreciate your input.
