2004 Colorado rough idle

I have a 2004 5 cyl Colorado that starts and run fine but after short warm up perdiod when I come to a stop the idle drops down and is rough for a few seconds then comes back up and is fine. Once in a while when the idle drops it feels like it's going to die but doesn't, pops back up to normal idle and is fine, anybody out there with suggestions? I did see a service notice a long time ago but was not a recall and referenced the potential for the engine to die on quick stops, related possibly? A few things I've already found is the throttle actuator assembly or update PCM.

Re: 2004 Colorado rough idle

I would have the pcm updated. When I had mine replaced there were over 170 updates. Also, I cured that very same problem when I had the truck tuned the first time by Canyon08Z71.

That should solve the problem.

Re: 2004 Colorado rough idle

Your gas filter should be replaced every 30k miles and the throttle body should be cleaned on around the same mileage, or as needed.
Both are part of the normal maintenance routine for these trucks.

Good Luck...

Re: 2004 Colorado rough idle

Thanks for both the tips, will replace fuel filter ASAP as it has quick disconnects and is an easy replacement. Is the dealer the only place to get PCM updates?

:( Sorry to say yes. What you tell them is you found out that GM has updates for your pcm. The service manager will look it up in the system and see you are correct. Then tell the service manager you would like to get your pcm updated. It should cost no more than $150.00 to do it.

Re: 2004 Colorado rough idle

Depending on your mileage, you should think about changing the plugs. My 2005 started having rough idle last year, so I did the normal maintenace and replaced the plugs -- they were nasty at 87k miles.

Re: 2004 Colorado rough idle

Based on the replies I have received sounds like a good maintenance overhaul is due, plugs, filters etc.

Thanks

Re: 2004 Colorado rough idle

clean your throttle body. i have a 04 5cyl it had a rough idle and it would cut off when i came to a stop. take it to a shop and tell them clean the throttle body i had mine cleaned last week and it made a big difference.

Re: 2004 Colorado rough idle

The TB is not that hard to get to on our trucks. All you need is a standard head screw driver and a 10mm or 13mm socket, and pick up some TB and map sensor cleaner from your local auto parts store. If you do this make sure to get the 2 cleaners. This will save you some bucks and time at the shop.

Re: 2004 Colorado rough idle

I don't see any water signs in oil nor do I get excessive smoke in exhaust. Once I come to a complete stop for a few seconds the idkle is fine, it's just when I first stop that it's rough. Don't even know if rough is the right word, idle drops below normal but then bumps back to normal after a moment of being stopped.

Re: 2004 Colorado rough idle

I agree that staying on top of maintenance will prevent a ton of problems.

I had the same problem with my 04 a couple months ago. I replaced the spark plugs and cleaned the TB and haven't had a problem since.

Re: 2004 Colorado rough idle

Mines been doing this for 2 years now, but only in the winter time and if I don't let it warm up good. I'm sure it would go away if I could get up off my lazy butt and do the spark plugs and clean the TB!
