When i come to a stop the rpms go way down almost to the piont of engine stall. anyone have this issue or any ideas. oh yea, you guys were right the trans filter o-ring thingy was a pita to get out.

MAP sensor may be on its way out.... no codes?

no codes. getting worried about her,she needs to last me till the summer. i have the rr 2" and am ordering shocks and a bunch of other stuff but of coarse with my luck there will be catastrophic break down before the summer when i plan to install everything. after dropping pan twice and doing the plugs im physically and emotionally invested (blood,sweat,and tears)

Dont stress about it man.... catastrophic failures dont exist on well maintained vehicles. Hell you could've got a bad tank of gas...

If there arent any codes, just keep your eye on it and see if there are any changes. If a sensors going bad, it'll let ya know soon enough. If its the MAP sensor you'll probably get a rich or lean DTC from the o2 long before it dies on ya.

What plugs did you put in it?

Have you cleaned the throttle body? Pretty simple to do. I am sure there are even write ups on it.

@ duneslider cleaned the throttle body,i made sure not to mess with the connector attached to it.
@matt i used the champion copper plugs.
going to order a complete set of service manuals....can't hurt

Another cause for this is a vacuum leak. These can be a pain to find sometimes but a vacuum leak can cause this too.

Spray around the intake seal and vacuum lines with carb cleaner.... if you hear the rpm increase you've found the leak.
