Could be a problem with ECT (Engine Coolant Temperature) sensor or fuel injection system. Will need to test and check in order to discard.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

SOURCE: rough idle when cold

This could possibly be a faulty engine coolant temperature sensor. these sensors are prone to failing.

Code po171 on 1997 ford explorer 4.0 what do I need to repair on car


hey look at rear of vehicle and if you notice water coming out of the exhaust pipe when cold start . it may have a dodgy head gasket . & that's why its running ruff when cold there will be water in one the piston pots this clears after it has been started & blows it out the pipe very common with vehicle .so how to fix you can get a liquid additive that go's into the radiator that will seal this ...most auto shops sell this & make sure you buy one with copper particles in the mix will cost about $60.00 & if no water out of the pipe you have bad fuel good luck mines all good now after I put the additive in

P2285 code 6.0 litre ford deisel long cranking before starting after starts runs great but oil pressure gauge drops at idle


bad bearings on crank or worn oil pump. Pressure will be up when cold, but will drop when engine warms up. Check for knock in lower end. If so, bad crank bearings.

It's 12 degrees outside, how long should i leave the engine of my 2007 ford focus running to warm up?


Wait for the temp gauge to lift off of the low end stop. The car is then warm enough to drive. Be very gentle on the trans for the first 20 miles or so, because the transmission relies on engine heat to warm up the trans fluid. Cold trans fluid is very dense and can cause the transmission to slip, causing gear damage.

My 2000 1.6 ford focus hesitates when driving from a standing start


Is this when the engine's cold? check the auto choke

when it's warm -air ingress to inlet manifold - listen for air noise - you will also notice that it will hesitate when you accelerate
also check if servo vacuum is affecting the engine speed - when idling pump brakes if it is this then speed increases
Air intake sensor unit Now you need to get a garage to plug into the ECU [car computer]

Starts but runs ruff till it is warm.


Probably the EGR valve is stuck open. It is supposed to be closed when idling. Check/replace.
If your "check engine light" is ON, have the fault code scanned at AutoZone (free).
