Just purchased a '91 convt. A4 for my wife as a gift. It is my second C4 I have owned.

Car has 138,000 and was driven 39k in 12 years verified.

Although the previous owner babied the car it still has all the original wires,plugs etc...

I want to do a full tune up and replace the valve cover gaskets while I'm at it.

I prefer AC delco or equivilant quality parts.

Off hand what parts do I need and if anyone has part numbers on file that would be great.

BTW I do turn wrenches and plan on doing all the L98 free mods as time allows.

All input is appreciated.

The previous owner may have babied the vette, but it seems he totally neglected proper maintenance.

You should consider replacing all sensors along with plugs and wires.
With the knock sensors out (if the '91 has 2) that would be the time to
flush coolant from the engine.

Research plugs and wires, and buy quality. Oil/filter, tranny, axle oil need changing?

Oh yes all the preventive maintenance things will get done. Sensors,etc.

My FIL is a master auto technician and runs foreign auto repair shop. I usually give him a list of parts and $ and he will order them and receive his discount. Most of the time it is cheaper than auto parts stores

Right now I'm dealing with a code 41 issue and idle issue in another thread I posted.
