HI, that pesky little light is yelling at you i need fixed. WHen this light is blinking it means that there is a problem sever enough to cause damage to the catalytic converters. This most likely due to a misfire condition. I would recommend you take int for service or at the very least stop by your local Auto Zone and have the Check the COdes sored in the computer, they do this free and then come back and see what they mean and what may need done.. Good luck

00linc LS v8 has a little missing at times . not noticeable on overnight start up ,after driving for a while you can feel it when accelerating at times then smooth out an run like ck eng lite

If the is misfiring then the check engine light will blink and a code will be set for the fault, so if you have no light you do not have a misfire it has to be something else going on, have you had the fault codes read yet? Do that, any Autozone will read them for free, just ask for a OBD2 fault code test.

You have to find the reason the check engine light is on. This will aid in diagnostics. Also, are you buying fuel at the same place both times?

Blinking check engine light

its most likely an ignition coil. you are probably getting a spike in the electrical system. my lincoln ls does the same thing sometimes. the check engine light wiill blink for awhile then stop, and eventually it will stay on and run rough. every single time it turned out to be an ignition coil.

Poor fuel mileage; sluggish possible mis fire idle has very low rpms no indication of check engine light at higher speeds freeway speeds runs good but poor fuel economy wheres the power?

Could be a lot of things, but if you have not replaced the air intake plenum gasket, this could be causing some of the issue. Spraying corborator cleaner around the gasket with the engine running should cause the engine to smooth out for a short period of time - just a diagnostic.

Service engine light on my Infinity 2001 QX4 4WD goes on and stays on usually for a couple of weeks then stays off for weeks, the code shows up as 420-430 which I think is catalytic converter, it's been...

The Service Engine Light means, time for an oil change and other regular maintainance items like engine air filter, check all other fluids, lube chassis, it's a reminder to take care of your car. When the maintainence is done, then you or whoever works on it resets the light, and it will come on again at the next proper interval. Every 3000 miles or 3 months whichever comes first is the standard.
Take good care of your car, it will cost you a bit, but your car will be happy and it will take good care of you. Neglect your car, it'll cost you much much more and you'll be sorry.

Bring it to Auto zone parts store to check if any trouble codes are present they will hook up a scanner for free, the code if present will point you in the right direction if no codes are present the car most likely needs a tune up, when these vehicles get older the fuel injectors become less efficient and need professional cleaning, O2 sensors should be changed every 60 to 80,000 miles whether the check engine light is on or not.

Code p0300 and p1406

P0300 is misfire and p1406 is EGR. It sounds like you have a chunk of carbon stuck in the EGR valve. Remove the valve and clean the carbon from the valve, bottom side. Then install a screened gasket so it won't happen again.
