Is there a fuel cutoff relay on the 1997 Audi A8 Quatro 4.2? I am having a problem with getting fuel to the motor. I replaced the fuel pump relay, also the fuel pump was replaced a few miles ago. The car...

Don't use starter fluid the car becomes addicted to it very quickly. Have you checked that there is power supply to the pump / fuse / relay. If there is then check that the fuel is flowing through the pipes / fuel filter and into the fuel rail

I have a 1999 audi a8 q it is runnen rough had a tune up dun that did not fix it and also had oil changed.had it put on computer and shows the number 4 sparkplug sumtimes it will run...

no heavy oil not going to help misfire. if you have a cylinder misfiring it has to be plug,plug wire,coil ,dist.cap &rotor,vavle,or piston rings ,an sometimes it can be headgasket . what u need to do is a compression check on all cylinders to compare to rest of them & do a leak down test on each cylinder only if the compression test are all the same psi. on all cylinders if u do this you will find the cause of the miss fire .

Sounds like the Catalytic converter needs to be looked at or replaced.
