Why would a 1990 Buick Electra misfire after it warms up?

Yes, but why would you want to waste the money on that boat.

It means that more than one cylinder has a misfire history. PO301 would be cylinder number 1 misfire. PO302 would be number 3 cylinder misfire.

The Purolator oil filter L10111 fits several cars. A few of them would be the Buick Century, the American Motors Concord, Eagle and Spirit, the Asuma GT and SE, the Buick Electra, Lacrosse, and LaSabre.

That would be the nose. It warms, filters, and humidifies room air. Its our built in heat and moisture reclaimer.

LOL the better Question would be what doesn't it fit. http://www.wixfilters.com/filterlookup/PartApplications.asp?Part=51036 Here are just a few follow the link for more BUICK CENTURY/CENTURY WAGON V6 2.8L 173 CID BUICK CENTURY/CENTURY WAGON V6 4.3L Diesel BUICK ELECTRA/WAGON/PARK AVE.

My guess would be GM, particularly Buick.

P0303 is cylinder #3 misfire. P0300 would be random misfire. Either way you need to diagnose the case of a misfire. Check spark plugs, plug wires(if equipped), cylinder compression, fuel inectors, and wiring.

I would replace the control module within the distributor ( $ 25.00) It is not hard to do. This module is a microprocessor and as they age they are sensitive to heat. As you drive your car it warms up and shuts off.

Did you try correcting the ignition firing order, from the ignition coilpacks, leading to your spark plugs? Also Unless you have a PCM scanner, or has had your Buick scanned, & know for sure you are in fact having a misfire, I would look into your fuel system (fuel rail, fuel injectors, fuel pressure check.). You may have a clogged injector spraying at two or more of your cylinders, causing a misfire.... I hope this information could help you. mdjblue78@yahoo.com

If it had a power ant. before the easiest would be to find the break in the wire so it works as it did. If it's new then you will have to run FUSED power to it from a source in the fusebox through a switch that is able to control the up & down.

Are u using super unleaded gas? if so stop!! use only regular . the super has to high of a fuel voltality and causes stalling when cold.

I'm not sure what you mean by sluggish, but 2 things I would check is that the fluid is full, and that the filter has been changed in the last 30,000 miles.

most likely be a coil PAC

it will feel like a misfire but should not cause a single cylinder misfire code. a bad maf ( mass air flow ) would and can set random multiple misfire codes, lean bank 1 and 2 just like a clogged fuel filter or restricted exhaust ( cat )

It would depend on what model of Buick you are referring to.

If you're looking for a Buick, I imagine it would be.

There are several things that can cause your 2003 or Expedition to misfire. The most common cause is a plugged catalytic converter.

If the cap is defective, probably not.

i would use a code reader for this.

A 1998 Buick would have been built with R134a.

A defective aspirator valve would unlikely cause a misfire monitor failure. It would more likely cause an air system monitor failure

You can check the battery connector. Make sure they are not corroded; and see if there isn't any melting on it; sometimes it will startup but drive rough, make sure the the connection is tight. Also I think platinum spark plugs come standard on some Buicks, which have a very small electrode and a little gunk will cause them to misfire; I would swapped them for a set of old champion copper plus spark plugs and a new set of spark plug wires.
