Cold start weirdness Posted by MC [Email] (#1472) [Profile/Gallery] (more from MC) on Mon, 29 Apr 2013 08:52:16 Members do not see ads below this line. - Help Keep This Site Online - Signup |
2005 9-5 AERO Wagon. ~87K miles.
First start of the morning: Starter cranks weak and even clicks a few times like the battery might be low (Note: battery is new=ish/recently replaced). Starts up and stalls out almost immediately.
Second attempt: turn key to start....delay before cranking..?..starts cranking, reluctantly again, Starts running after normal amount of cranking but with an obvious misfire (running rough). smooths out in ~10 seconds. No smoke from tail pipe and no check engine light or fault codes stored (yet).
Starts fine the rest of the day.
ALSO NOTED: IDM (Ignition cassette) and spark plugs recently replaced. Due to P1311/P1312 and P0340 codes. Replacement plugs were NGK laser platinum.
I have a few hunches but have not started a diagnosis yet.
Any one experience these symptoms? thoughts on this?
Looking for some brilliant ideas before i get into it.
