My 1996 Audi Cabriolet is having transmission issues...it only has 95,000 miles on it.....the check engine light has frequently come on and when the mechanic codes it it says there is a misfire of a sparkplug...the trans started acting up about 6 mos ago and they found a small hole somewhere..they fixed it....about 2 mos ago the oil pressure light came on after ....they replaced the sensor after checking that the oil levels were fine...the next day the light came on again after I had started it up for the 3rd time that day...they checked the oil pressure and it was fine....now the trans starts sticking and bucks after I come off the breaks and the oil light flashes....it usually occurs after the 2nd or 3rd time I have started the car in a day.....could the misfiring spark plug have anything to do with this....the problem was never corrected.....I am going to have to get rid of the car if I need a new trans..I have already put too much money into it....do you have any ideas about what is wrong?

You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.

It is necessary to replace rings on pistons.

Sounds like carbon build-up in the cylinders. Take it and have it put on a machine called a "Motor-Vac"

it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps
