i have a 2000 audi a6 2.7L bi turbo iautomatic
car will crank but will not start, i have fuel, spark, compression. epc light is on and check engine light is on. every once in a while the car will start but runs really rough hasno pedal response. recently replaced the maf sensor i do not know the codes at this moment. any help with this will be greatly appreciated

well without codes harder to say but.....2000 a6 2.7t can melt the engine harness across the back of the engine if it wasn't properly secured and insulated. It will cause bad mafs codes and so it is often misdiagnosed as a bad mafs.

now you say thats on the back of the engine right. but how would that cause to run somedays and not srun at all other days

There is no fault on a car that could give more random problems then bad wiring.
