Same Problem

-   well i took a little different approach and started to replace the coils and spark plugs.  
After two coils ($50.00 a piece) and sparks plugs all 8.  it ran good for a few days and then the symtoms came back.  Sputtering and shaking and when at a traffic light the engine will not run over 3000 rpm's.  
I am looking now for the speed sensor.  Next step is replacing the other coils.  Will try the battery things also now.  Hopefully it is a computer thing.

-   My car seems to run just fine but the ck engine light keeps coming on and off randomly. Now it won't pass smog because of the light - not tail pipe emissions. My mechanic says it is likely a problem from the dual mass flywheel which has pick up points on it that the engine management computer uses. So if the flywheel is wacky, the computer gets a bad signal and sets off the light. Argh! -   tmgan

-   rough idle car cuts off feels like when you have bad gas. Check engine code comes up for ignition coil short. I thought it could possibly by a sensor that monitors TPS or tach

P1633 means KAM (Keep Alive Memory ) Voltage too low. the KAM is caused by low battery voltage and you replace the battery.When you replace the battery the KAM loses Memory and the problems resulting in what you are experiencing now.When replacing a new battery, reconnect the Positive cable first.And use a trickle battery charger set low to the cables before disconnectng the battery . this will keep the voltage to the ECM powered with enough voltage. All you can do now is make the computer relearn the way it should run. Disconnect the negative cable from the battery, wait a while 20 seconds or so. then reconnect the cable. I do not know if this is a temporary fix or not but it should re-program the computer.
