Rough idle
 

My truck has a rough idle for a few seconds when I first start and sometimes when I push the clutch in to stop. Just anybody know what causes this? Is it a bad thing?
Also sometimes when I go to start it, I will think it is goin and when I let off it just dies. Then I start it up again and it has a little white smoke come out? I'm just trying to figure out if something is about to go out or if that is normal? My buddies has a rough start too.

How many miles on the truck?

Next time before you start it, Check your HPOP reservoir level...

Only 98k. It only does it sometimes. Like earlier I was messin with my exhaust and started it up and it was perfect and revved it up and it did perfect. It only does it sometimes. But when I put it in neutral and roll up to a traffic light, I can feel it idling rough and the gauge jerks a little

I had a similar problem. It was the dual mass flywheel.

I just had a new clutch put in at the dealership? Prolly about 2-3 months ago

Also do our trucks have intercoolers or is that the trans cooler in the front at the bottom or what is that?

Also my buddy has a 97' that has an automatic trans and his does the same thing starting up?

No intercooler on OBS trucks...

Mine used to lope when I first started the truck, Doesn't do it now that I swapped injectors.. That shouldn't be your problem though.

So what is the little radiator thing right behind the bumper?

hey, i've noticed my truck will stumble and lope if i'm pulling up to a redlight and kick it in neutral to coast to the light at say 5mph or so. i dont think its in the clutch, but it could be? my trucks a 95 dually, manual.

You didnt happen to replace the dual mass when you did your clutch did you?
