My 1998 A6 2.8Q. has 157000 miles.

Runs good, just some vibration exists while stop.

I checked the codesat theAutozone.

P0300 : cyl
P0303 : cyl3
P0302 : cyl2
P0301 : cyl1

P0455 : Evap ECS leak(large)
P1857 : Manufacturer Transmission C
P1138 : Fuel Air Metering
P1136 : Fuel Air Metering
P0102 : MAF Circuit low input



So, about the1st to4thcodes.. I've hadnew spark plugs and wires. Then, probably the coilpack problem, am I right?

Anotherfive codes.. I have no idea.. Please give meany advices.

P0102= You may need a new Mass Air FLow Sensor. And faults P1138 & P1136 could be related to that fault.
P0455=You have a large leak in your Evap system. CHeck your gas cap and see if it's even closed.
P1857= Don't know. Might have to ask the dealer for Specifics on that code

Thank you sir.

By the way, light turned off.

No lighting on now, but I am going to do what I have to.
