Hey guys,

Lately my Max has been running rough at idle. Currently there is an O2 code and KS (which was replaced today). It feels just like a misfire at idle, and the car stalls sometimes when coming to a stop.

The coilpacks are fairly new <10k miles on this set, but I haven't had a chance to check them yet.

An O2 wouldn't cause the car to miss at idle would it? Any ideas?

Thanks.

p.s. MAF maybe? Wouldn't that affect the car at all speeds though?

 

i too have a front right o2 code. My car has never stalled while stopping. Try raising your idle to be at 600-680 rpms with no load (in neutral). while your'e doin that, clean your tb and iacv. should be 2 hours tops for everything.

 

Will do this weekend, weather permitting. What's wierd is that my CEL turned off the other day.

Thanks for the help.

 

had the same problem about three days ago.. bad coil pack..

 

But they're soooo new.... =(

 

Coilpacks... grr! You'd think that from 95 to 99,they'd figure it out by then? Hmm.
