1999 saturn sw 5 speed

Sounds like a misfire. But honestly it could be anything. If the check engine light is on that could point you in the right direction

The LW started in 00, if it is a 99 then it is an SW. I would start by replacing the crank sensor which is installed into the rear of the block, behind the starter on the SW. Most likely easier to replace on the LW as they moved the starter to the front of the engine in the 2.2 LW engine. Cheap part.

1998 Saturn SL1 5 Speed everything manual except Cruise Control. Run Great. Every time I start it, it goes through it's check cycle and comes back GOOD. But as soon as I move approximately 20 feet the SERVICE Wrench Light comes on and stays on until the car is shut off. This happens every time, doesn't matter if I go forward or reverse. All checks have turned up nothing. No codes. I checked the wiring and have found nothing. I have checked and replaced any and all bulbs, including the ash tray bulb. I have replaced the Cool Fan Relay. And still the problem exist. Any feedback or advice would be greatly appreciated.

Its time for an full ignition tune up and paying close attention to ignition cables and crusty connections at the coil towers where the wires connect.

Your MAF sensor is dirty. It's in the intake and can be cleaned. Use CRCelectronis spray cleaner. do not touch ,rub, or brush delicat and very expensive. do not use compressed air, It will dry on its own. Location, in the air intake ducting in a metal dectio, Wires should give it away. Good luck and make sure your air filter is kept clean and leak free. Ned_

Probably bad ignition system which can be anything from a failing coil pack,ignition wires or cracked spark plugs. Look closely for signs of missing by looking for cracks in plugs,bad plug wires or a white/green crusty chalk build up on the coil

is the check engine light on?

check ur charging system(batt and alt)

This could be a dirty filter. i would start there and replace fluids with lucas tranny fluid. Does it change when the car warms up i wonder ?
