[QUOTE="mandkole, post: 1440165, member: 4630"] Hey all lend me your ear... it's been cold in the pnw and had a strange run issue from months ago in spring repeat itself today. The motor had cold soaked down to about 20f the last few days. Was a hard smoky start (not plugged in),hopped in and drove my mile to the highway then travelled about 10 miles and exited. EOT only got to 150f or so. As I got off the highway, noticed some unusual haze and pulled into fuel station. The white fuel smoke became heavy, but no knock, yet the motor was quieter like the timing was pulled. I checked the CCV tube and all good but noticed the PW was high at no load idle (1.5-1.6ms). Shut it off. I restarted it, the pw went to 1.3 (normal), the normal cackle came back and the pipe was clean. ICP and dc were normal and ran fine rest of day. What the frack? At this time I plan to change both the EOT and icp sensors to rule them out.. The EOT is about 50f high when cold and the icp has had oil in it. Could these drive a weird fueling issue? [/QUOTE]
