#1 of 2 2005 LS Sedan Rough Idle by silver2005 Feb 13, 2008 (8:22 am)
I recently purchased this Malibu from a fleet sale, so the car is new to me. Currently has 38k miles. Is there a TSB for curing the rough idle on my 2005 Malibu LS sedan. The engine runs smooth except for idling at a stop light. When stopped in 'Drive' or in 'Park' the Tach jumps around about 50-100 RPMs and there is a noticeable 'miss' or roughness in the idle. I read about some TSB for the 2004 that seems to address this, but I'm wondering if the 2005 needs the same cure. I think the 2004 TSBs were a reflash of the PCM. Any ideas? thanks Doug
