RE: codes
 

Are those for people who are to lazy to click the link I posted?

RE: codes
 

LOL, yeah. I have my own source for codes, but it is nice to have a list here.

We should probably setup a separate section for information like this. I hate it when there are like 10 stickies up at the top of a forum section, and I think that we would have that much if we were to start to build up a good database of useful information in one area of the site.

We could have an info and How-To section kind of like what I have seen on DodgeIntrepid.net and BonnevilleClub.com. These 2 sections would greatly help out the members. Mods would have to manage them however in respect to user submissions and keeping the threads cleaned up (if posting was allowed in them even).

RE: codes
 

yeah the only reason i really did it is bc there has been a lot of posts about codes.. i dont mind helping people out its just that you can pretty much find anything on the web these days. you just have to look... so thats why i did it it was like 2am lol

RE: codes
 

I also think that's a good idea. I wanted to ask you about doing some submissions about a month ago, but for SOME reason, my emails don't go through to you ;)

RE: codes
 

what year do these codes cover

RE: codes
 

also have to watch the format they are posted in. If there are things like ( , #, @, &, and such posted too close to them then they will not show up under a search.

Like if you posted (P0103) as to ( P0103 ) or even (0103) as to ( 0103 )
The ones without the space wont show in a search, the ones with will.

Mine doesn't show those codes, I don't even need a reader, just a paper clip bent into a U shape, place it in the code port and turn the ing on the check engine light will flash simply wright the number of flashes down ona piece or paper, and cross reference them in the Haynes manual. Mine crosses into numbers like 14, 12, 88, 53 like than, theres no P in front of anything, so I'm asking if that is for a different code system than I have in my blazer. Cause I've always heard that theres two kinds, one that requires a paper clip and one that requires a code reader.
