It was very cold, the car sat in the garage for 3 days with very lower fuel, now it idles rough and sounds rough, did I ruin something by not having enough fuel when cold?


No,low fuel isn't your problem. If there's enough fuel for the fuel pump to pick up your car should run okay. You haven't ruined anything. It's not your fault.

It is possible that a low fuel level - very low indeed - has allowed debris/dirt into the system and is causing a blockage. However, I think this is quite unlikely to be the problem you have.

You say the car idles rough - does it drive at speed okay? If it drives okay at speed you can rule out most fuel problems .. most.

Backtrack a bit .. has your car ever ran/idled roughly before? Cold weather can exacerbate a problem.

It could be the cold weather- fuel and injections system have cold start devices or sensors of one sort or another. It may be a faulty sensor. Get somebody to do a diagnostic check for you

Do you have a block heater? You can have on installed if not, then plug your car in over night. You car will run much smoother in cold weather.

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

2004fordtaurus3.0 engine runs rough in cold weather when started. like today in new york 13degee


You know what...there's nothing wrong with your engine...When metal is cold...it contracts...thus causing more friction between moving parts...this is why your motor runs rough in cold weather...I'm gonna give you a crazy suggestion...Have you heard of a "Block Heater"...it is a heated dip stick that you place in your engine overnight..
this device keeps your oil at operating temp overnight...so when you start your car....the block is warm...and the oil flows like magic..just pull out your dipstick...insert the block heater...and rest easy...of course...it has to plugged into a 110 volt outlet...You can find these online by Googleing it or go to www.yourautonetwork.com...Give it a try and let me know....I hope this was helpful....PEACE.....

Started in cold weather yesterday. Ran real rough, almost like a motor mount bad. Fan turns by itself when turned with your hand.


If it only happens in cold weather, check your intake manifold bolts for tightness. #5 & #6 by the firewall are easiest to check. Some people will find these not even hand tight = rough running car.

However, if (when cold) your car is vibrating at idle IN GEAR and stopped, this would be a motor mount on Envoys and Trailblazer, very common.


Fan shouldn't turn by itself, you may have a bad fan clutch.
