Now that here in the northeast the Temps are starting to get down into the low 30's,when I first start the car in the morning then go back out to leave for work about 15 min's or so later the car is still on high idle? I mean higher then normal.It does go down after I tap the peddle.The strange ...

misfire maybe?

Its my 98 ssei and its the valve that connects to the canister,it has a 2 wire connection to it.It is part of the evap system.You have the purge solenoid,vent valve and the canister.Its the vent valve that not one parts store seems to have.

Does anyone know what the part # is for the Vent valve?not the purge but the vent valve.Every parts store that I have gone to only has the purge but no listing for the vent valve.

I did get new wires....Onless its a bad set which I dought..

All I know is with the ngk 55's I got missfires so I went out and got the AC Delco 41-101's and have not had a problem since...

What I will do tomorrow is go get 3 new ones and see what happens and report back.But is there really a difference between say the ngk 55s and the champion copper plus as far as voltage used to run it?if so maybe that might mean coils going bad?I dont know..

I understand that but then why misfires with one brand and not the other?Did I just get a set of bad plugs?When I took out the ngks they looked perfectly fine.All I know is Im not getting misfires with the champion plugs.Its not that Im pushing one brand of plug over another brand but if someone can ...

93 octane cost more but your mpg will go up so in the long run it all comes out the same in the end plus your car will run better..

I think the ACDelco 41-601 is the same thing as the ngk 55s by the way....

You know I first put in platium plugs a few months ago and then reading in here that I should not use them in a sc motor I went to get ngk 55s but because advanced auto only had 5 of them I went instead with champion copper plugs..Not a problem with them what so ever.But still wanted to try the ngks ...

Right now Im useing champion copper plus spark plugs that have a heat range of 14.I was thinking on getting the ngk 55s which have a heat range of 5.My question is what if any difference in the way the engine runs will I notice by switching.Is there a big difference in a heat range of 14 vs 5?

thats the same as the engine mount right?

The plugs are new and so are the wires.About a week ago I was getting a p0401 code(Insufficient EGR Flow)plus a p0306 code(Cylinder 6 Six Misfire)So because of the p0401 code I took the egr valve off of my 95 bonneville and put on the 98 and the codes went away till today.Not getting the p0401 but ...

Well all was good for about a week,now Im back to getting the p0306 code.Also blinking to boot.Getting fed up with this...

Ok,thanks! I will be ckecking in later..

I know,another dumb question but does it say on it what it is? if not does it look like a relay of some kind?A pic of it would be great.You see I have to pull the fuse for the inside lights because they will stay on other wise for the 10 min.So right now I have a toggle swith hooked up so I can turn ...

Where is the Retained Accessory Power module located?

Yes I did read that I just couldnt find anyone who tried it on a bonneville.

The other day I started getting a p0401 code(Insufficient EGR Flow)plus a p0306 code(Cylinder 6 Six Misfire).So after some reading I took off the ege valve,cleaned it put it back on and still got the same codes.So I decided I would take the one I had off my 95 bonneville and put it on my 98ssei.Have ...
