revised: low idle after repair
ok...so i think i have the egr problem fixed, unfortunately i can't exactly find out if i'm right. This post will have 2 subjects
(Oh, and to the other mike out there, somewhere, thanks for tipping me to airing out the the throttle body, you're right about that rick guy, right on! and to rick? You rule!!!!!)
1)the EGR: Anyone else researching the egr code p0401 on a sable or taurus should definately go through the pain of taking off their throttle body and cleaning out that port. definately. it is the problem, if the sensor didn't work, i guaruntee it! Do not replace the valve until you are out of other options. But be careful! that retention clip that was in the way of your post screw on the bottom right part of the throttle body? It will get stuck behind your gasket and cause all kinds of removal problems when you notice!
2)my real problem, a low idle. really low. like, moving the engine back and forth low, i mean, sounds like my car is dying low. like, "please, kill me now before it gets worse" low.
The smoke went away fairly quickly after another restart, and airing out the throttle body made the start very smooth. but now, both the other mike and i are experienceing the same problem, a very low idle. when accelerating there is no issue, at least not audibly, i moved the throttle conrol by hand to rev the engine, and the sputtering went away. the old battle wagons, apparently, like to do this....darn grocery getters. who needs duals on a wagon anyways??? seriously. it's a station wagon!
so-is it the air idle control valve (whatever that is, i guess i'll find out at autozone tonight)? or, like i was asking before, could that solenoid vacum (i think it is called the evr) be causing all of this grief?
where else do i look for a vacum leak? all the egr hoses are back on and right, and i don't know what else i could have knocked out of place.
