      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

2000 Pontiac Firebird

My son has a 2000 Pontiac Firebird with a check engine light on. The codes were scanned and they are p0405 and p0300.  Any ideas or insight would be greatly appreciated. Thanks!!

Is it the V6 or V8 motor? The V6 of that vintage had EGR valves that would often carbon up and stick and/or fail causing a random misfire and rough idle.

It is a 3.8 v6. Is there a way to clean the EGR or should it be replaced?

Typically the engine will run a little rough at idle if the EGR is stuck a little open. You will see a metal tube coming out of the EGR valve. if the tube gets hot (carefull as it can burn you) while the car is idling than the EGR is likely stuck open a little.

Removing the valve and cleaning/soaking in carb spray may help. You will likely see a lot of carbon around the pintle. You may even see that the pintle is being held open a little by a chunk of carbon.

My son replaced the EGR valve and it is still sputtering, gets terrible gas mileage and slow to accelerate. He also replaced fuel filter, spark plugs and wires.

I think this none might be old enough to try this trick. unplug the MAF sensor. if the symptoms are noticeably less obvious than it might be worth cleaning it or replacing it with anything but a re-manufactured one. it is also common for the pigtail or connector to go bad on these as well. typically you can wiggle the connector and get it to either act up or stall.

That little tube under the EGR is hot when the car is idling.  So you think it still has something to do with the EGR??   We unplugged the MAF and it maybe changed the idle a little but not real noticeable.

The EGR tube should be checked at a cold start. If it gets hot shortly after start up than I would suspect there is still something wrong with the EGR system.

 

I think at this point some scan tool data would be beneficial. A couple of things I would be interested in seeing is the upstream (sensor 1) O2 data, Short term fuel trim, and misfire counters if available.

 

At this point I am wondering if there is a plugged catalytic converter. Easy enough to check with a backpressure gauge. Or the red kneck back pressure test would be to drop the exhaust from the manifold and take it for a quick test drive.

Well that was easy, relatively speaking....

I guess I assumed that spark was checked. Should have recommended that right off the bat.

Glad he has it purring like a kitten!!
