Rough Idle at start up

[JL's95GSX]

So its at random times, car sat for a week starts fine. can sit over night get in and its a rough idle when start for maybe 2-4mins then it clears up. so i dont think its a cold or hot start problem.

Any ideas where to start ?

No leaks recenty checked


Thanks

lack of lubrication, and with the engine being cold.

change your oil filter and oil. and see if still does that, try using a lower viscosity oil if. that should fix the problem, i know its Florida but they have been having some colderish weather haven't they?

True i was kinda thinking that the recent weather change could be playing into it...

Is that a possiblitly that the weather alone could cause it? and yes im gonna do a oild change and filter, what velocity would ya think would be good to go to, also it is and should be warming back up here will going down in velocity also have a affect if it gets back to 80+ daily


Thanks for the info

Weather never changed the idle for me just a little louder and a bit longer to warm up since up here in NY it ranges from 30 to 0 degrees outside but a bad battery terminal did. Clean your post and make sure everything is tight. Just a suggestion

Well its been doing it at random times...

But when i was checking around the terminal was loose tightned it earlier, only drove the car once since then so see if that has an affect.

Thanks for the input

well im from wisconsin and if you went and put "Summer oil" in your car during december-march. your batter is usually gonna end up dying before you get it to start. it will crank so slow..usually idles rough for the first 5-20 mins if you got it started depending how cold it was.
