...that it is missing on number 1 cyl? Experiencing the following anomalies with my 2001 Saturn SL1: Error message that it is missing on number 1 cylinder but getting 32 – 34 mpg replaced spark plugs and wires. Used fuel injector cleaner for four tanks full with no change. Hard shift from first to second, only when it is cold and within the first mile, then it is OK. Error message that it is not going into overdrive, but counting the shifts and watching the tack, it does. Intermittently will not be able to turn the ignition key to the lock position. The key stops the engine and electrical but it will not go to the lock position. Intermittently very difficult to take trans. (automatic) out of park. Everything above is intermittent and seems to be tied to humidity/moisture. Any ideas?
