Whats up guys. I really need to know whats going on, occasionally my Check engine light will come on, and at random times my 99 a4 2.8qm will not start. It cranks for about 20 seconds, I usually keep stepping on the gas, and then it will start. I am worried that it will get worse, It's scheduled for maintenance but I want to give them some idea of what might be going on. You think oxygen sensors need replacing? Please help thanks.

 

Ugh...

Does ANYONE read the stickies?

 

i had the same problem with my car about a month ago, cylinder's 4 and 6 misfired and had to replace the lines connected to them b/c they were cracked, and had the spark plugs replaced as well just for basic maintenance.

 

what did that cost to replace?
