You drove with a flashing check engine light and then with it on solid. Flashing check engine light means STOP DRIVING and get it fixed. So this sounds like an abused and neglected car to me. Get the trouble codes read that are stored in the computer. Check for good fuel pressure and spark. Fix one or both.
Replace oil and oil filter the oil is clogged up and needs to be replaced, Replace oil with a High viscosity oil you require more lubrication when cold a good Motor spares will be able to assist you with the correct oil,The noise it makes is cause the oil is not lubricating the cranck shaft and bearings and hydraulic tappets this is like a rumble noise,Only happens when the motor is not getting a good lubrication Caution if this continues to happen the motor will start to run dry and seize all bearings starting with the cranck shaft bearings.try to get synt synthetic oil expensive but will work .But do ask where you are buying for the best oil for low temp weather they will assist.
Although your pollen filter will not cause the engine to cut out, a lack of oil pressure will. Check your oil level. Then take your vehicle into a dealer soonest.
if you notice it when it is wet out then i would do a tune -up but if not i would check the fuel injectors because they are a very very common problem with these years of cars. i do them all the time.
please give me a repair history and i will try to help.
LIKE I TELL MY CUSTOMERS...FOR STARTERS YOU NEED BRAKES BECAUSE IF IT DOESNT STOP IT DOESNT MATTER.IF THE O2 SENSOR IS BAD THAT WILL THROW OFF THE WHOLE EMMISSIONS SYSTEM.WHICH CAN CLOG YOU INJECTORS,RUIN YOUR PLUGS,CAUSE YOUR CHECK ENGINE LIGHT ON ECT.YOUR COMPUTER KNOWS THERE IS A PROBLEM & THE CAR WONT RUN WELL UNTIL ITS FIXED.STEP 1- BRAKES,02 SENSOR,TUNE UP,OIL CHANGE....WHATEVER ELSE YOU NEED.I KNOW IT STINKS.,JUST DO IT ONCE & DO IT RIGHT.
\I WAS HAVING THE SAME PROBLEM, IF THE CHECK ENGINE LIGHT DOES NOT COME ON, IT COULD BE A CLOGGED CATALETIC CONVERTER, THE EASIEST WAY TO TEST THIS ,TO ME ANYWAY, IS TO DISCONNECT THE EXHAUST PIPES(COMING OFF THE ENGINE) AND THE CONNECTION TO THE FRONT OF THE CATALETIC CONVERTER, THEN START THE CAR AND SEE WHAT IT DOES, IF THE ENGINE SURGE GOES AWAY(REMEMBER THE CAR WILL BE LOUD) BUT YOU ARE LOOKING FOR THE ENGINE HEALTH TO GO TO NORMAL, IF IT DOES YOUR CAT IS CLOGGED
It will take a while for the oil to circulate throughout the engine at that cold of a temperature. You may want to get an oil change done and make sure you have the proper oil for the temperatures. What happends is that the oil gets thicker and has a harder time circulating through the engine. BE VERY CAREFUL leaving the car run with the oil light on. You can blow the engine very quickly as I learned the hard way. Good luck to you and thanks for using FixYa!
