Lube and oil change requirements

If not reachable from underneath the engine tips forward to change they make a holding tool. Loosen the dog bone engine mounts and lean on the car you'll see the engine move pull it forward with a bar then find something to hold it there. I hope this helps. Take Care.

You can go to a nearby parts store and purchase a Haynes automotive reference guide and it contains all the different diagrams that would need. On the front of the book it would say 1990-94 lumina cutlass etc.

Check the wire from the module to the crank sensor. They go bad. Usually from oil leaks. Is it saturated with oil where it goes under the engine? Also check for power and ground on the two wire plug on the drivers side of the module. It isn't the ecm or anything with it. The ignition system on the 3.1 will work with the ecm unplugged. The ignition system is a stand alone system. It sends signals to the ecm for the fuel injection.

Usually you want to change the oil every 3,000-5,000 miles. Have the lower ball joints and outer tierod ends, if they have grease fittings.

I am having a similar problem, but there is no check engine light. It seems that mine dies at the light or running, if the rpm's drop. I am wondering if the Idle air control valve is bad or possibly the ERG valve?

The wet plugs are not firing. The engine must be running rough. Check for spark on the middle two. Find the problem and change oil and filter.

Change ignition coil pack.

it all depend on the millage, and how dirty the oil is

if oil very dirty it will be worst for your transmission

3 on front and 3 on back of engine. the wires coming from coils,on top back of engine,

have u checked the fuel filter and check to make sure the sparkplug wires are all correct and the wires for the ignition system ned to be checked also
