Cold start, fluctuating/surging at idle rpms.. Cause/solution?
Hey I was wondering if you guys had and insight as to what this may be..
Left the car for a couple days without starting it and then came out today to drive it. Upon starting the motor I could feel the idle going up and down 'surging' if you will. The RPMS fluctuated up and down a few hundred, but it stopped after about 30 seconds, once the motor came up to temp.
Any Ideas? Thanks

Hrm, it did it again today, so I ordered 16 new iridium plugs. Also doing an oil change with the 0w-40 mobile synthetic, replacing the fuel filter, installing a new hi-flo IC pump (thanks for the tip radride) splashing a bit of seafoam in the tank, and a bottle of water wetter in the radiator.
That should do for a nice tuneup.
edit I forgot to add, K&N air filters too.
