Engine I'm looking for an used car engine for my 93 Saturn SW2.  Any one have any idea where to purchase it? Thanls Sal

Idling check worn engine mounts. If driving look a faulty ignition like spark plugs or wires etc.

Probably accelerator/fuel mix sensor? Check the codes at a parts store like Pep Boys, Should indicate the bad boys

There is a coolant sensor ,it could be bad,or the relay for that fan maybe bad.

Sounds like a relay or fuse problem, at worst it's your fan #1 has gone bad and needs to be replaced. Before replacing anything, check all your fuses, relay, wire leads and harness at the fan.
Good luck and thank you for using Fixya.

First off an engine code 7 would mean it is a DOHC and an SW2, not SW1.

Do you have a dealer filter or aftermarket? The aftermarket have fitment issues (as well as flow issues) and it is best to use a dealer one.

Second, make sure the magnet is not on the filter area where it spins on. That can be removed during the first transmission fluid and filter change. It is only put on from the factory and removed afterward.

Trans has to be either removed or unbolted & moved away from engine 3" or more to gain access to clutch assy.If you remove trans all the way Cradle needs to be removed & engine supported with special tool.Big Job On the ground!!

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too
