Question about 2001 Lincoln LS

Check Engine Light

01' Lincoln LS V8, My check engine flashes when I get on the gas, then when I come to a complete stop it goes away. I just changed my O2 sensor before the cat, then cleaned my MAF semsor. I already cleared codes P0174, P0153/4 before my CEL started flashing, I have a K&N air filter (cone). I might have over oiled my filter but I need to know just in case. Thank you

Scan the computer again for codes. driving the car with flashing ck engine lite is damaging the valves and the cat converters. any po300,1,2,3,4,5,6,7,8 codes indicate that cyl. #misfire. most likely plugs and/or coils. if the po174 is back i would take a look at a possible vacuum leak in engine somewhere. the o2 sensor could have fixed the 153/4 but still could be more

Check engine light flashing car missing badly

A flashing check engine light is generally for a really bad, active misfire that is causing unburned fuel to go into the Catalytic Convertor. Without a code, I cant really point you in the proper direction to fix it. I would recommend getting it professionally looked at very soon, or if you or a buddy know how to work on an engine, go to one of your local auto parts stores and have the code pulled for free to at least give you a decent idea of where to go. Given that you are driving a Gen I LS (I am assuming the 3.9L V8) coils and plugs are probably the most likely culprit (and possibly valve cover gaskets). There is also the possibility that the plastic tensioner for the timing chain has broken, causing the timing to go bad.

Pull the MAF sensor and give it a cleaning the correct way.Sometimes something shorts those probes(tiny wires and delicate) and your engine will cut a shine on you.
Look up how to clean the MAF sensor if you don't know how. don-ohio

Misfire from one or more of your cylinders, Have the code scanned. Most likely going to need coil(s) and spark plugs to fix the problem.

i just had mine fixed for that very same problem have several "coils"/sparkplugs that should be should have it put on a machine that will read which one it is....problem targeted. The best thing to do though is change all of them. they break 1 after the other. i replaced 2 within 3 months. Later i decided i didn't want to go have it done once a month, so i bit the bullet and spent the money.....
