Ruff idle when cold
1994 1/2 f-250 extended cab. I have a hard cold start and ruff idle when cold. When you start to drive it there is little power and run quite ruff. As the temp comes up you can feel about 3 stages of improvment, it's like you are flipping a switch, after the third time it will run fine and has full power.
Today I took the ICP sensor plug off and there was no difference in the way it ran. Didn't get a check engine light.
There is no smoke on start up, but if you let it idle for a while say 10 -15 minutes it will blow a grey/blue smoke for a minute or so.
The truck is stock except for a round down pipe.
The glow plug are good comming up on two years old. GPR is ok also.
Thanks for any help.
