Cylinder Misfires

[tj19855]

Started the car today, it was cold outside, It started having multiple cylinder misfires when on idle, CEL started blinking, car started to shake so I drove it anyway, What could be causing it? I did replace the ignition coils a few months back and the spark plugs. Now my Oxygen sensors are bad could this be causing the misfires?. Looks like every time it gets could outside my car starts acting up.

Did you put colder plugs in last time around? Bad O2 sensors could be messing things up too. How many miles do you have on the motor? Did the blinking CEL go away once the car was warmed up? I have cold start misfires when using cold plugs. Goes away once warmed up for a bit...

106,500 miles on the car, I dont know what kind of plugs I have the shop I took it to probably put cheap ones on. Yes the blinking CEL went away after it warmed up. Last time I did a Vag-Com reading I had mostly all cylinder misfires, oxygen sensors and catalytic converters not working.

Sad to say but this is pretty normal. 3.0's run lean on start-up, not really damaging but just really annoying. The shaking car part...not so normal that seems like it could be more then a misfire.

One of my plastic tube broke and was lossing air pressure, so thats why it was misfiring cost $400.
