Rough running only first thing in the morning

Asked by Mar 30, 2015 at 06:41 PM about the 2003 Dodge Caravan SE

Question type: Maintenance & Repair

I have a Dodge Caravan 3.3 2003 that runs rough for 5-30 seconds first thing in the
day.  Then it starts and runs fine for the rest of the day.  It went into the garage for this
fault and they found that the inlet manifold was leaking so replaced the gasket.  It runs
much smoother now during the day but with the same rough start.  The garage
checked the compression for head gasket (fine) and the spark plugs and HT leads
which were fine too.  They say it is now a process of replacing things.  Does anyone
have any ideas what it could be.  Any help would be great thanks.

Is this to fix a sticking butterfly on the intake and or sticking solenoid on the IAC?

Remove the iac and clean it,all so,butterfly can be cleaned with carb cleaner.

The only other thing you may check would be the EGR valve may be bad.

Something I did not mention is that the roughness continues even when you rev the engine which would negate the IAC I would have thought. So maybe not the IAC?
