EGR circuit malfunction. Your exhaust gas recirculation valve is not operating properly. The valve opens under certain conditions (mostly off idle) to recirculate exhaust gases back through the intake and through the cylinders, to lower combustion temperatures for cleaner emissions.
Often the valve itself, or the passages under it, get clogged with carbon build-up and cease operation. Take the valve off and clean it with a wire brush and maybe a small blade. If you push up on the valve's diaphragm, you should see the pintle on the bottom of the valve raise with the diaphragm. If it doesn't work right, replace the valve (a salvage unit should work). Also take the blade and clean out the passages of carbon. Clean them as best you can so the passages are not clogged up. Then put the valve back on with a new gasket, if needed.
Some people just do away with the egr valve when it stops operating, by taking off the vacuum line to it and plugging the vacuum line off. Then the valve cannot open. Sometimes the valve gets stuck open, resulting in the engine idling poorly.

SOURCE: Oldsmobile cutlass 1993 Wont engage when engine cold.

Check your transmission fluid level You will need to top it up if low. Low fluids mean that not only will the transmission be slow to respond but when it engages gear it does so with a bit of thump. If the fluid stays low this thumping of the gear changes will eventually shear off the input shaft. Also check the linkage located from beneath the gear shift to the transmission casing and adjust it if necessary. My guess is that topping up the transmission fluid to its proper levels will solve the problem without need for any adjustment

SOURCE: i need to reset the timing on my 93 oldsmobile

You must have an ignition distributor to be able to reset or change the engine timing. If you do have a coil pack then the engine timing is completely controlled by the computer and there is no timing adjustment.
