Hello all~
I may not have a dodge neon,
but i DO have a 95 Mitsubishi Eclipse,
which has the same engine as a DODGE Neon 16 Valve DOHC,
if you know about this, i need your help!!
** What happens**
After about 6 hours of my car sitting I turn it on,
I believe the carbon combustion hardens or something and the IAC (Idle air control) or SOMETHING clogs, and then when i start to go and come to a stop and i take my foot off the gas,
it dies,
the idle does not catch in the 1000 rpm,
so what i believe is the throttle body needs cleaning,
does anyone else know something!??
And I know it's not JUST the Idle Air Valve because that was replaced at the warranty!

I am only 18 and bought my first car,
am now the owner of a 95 Mitsubishi Eclipse GS,

Suprirsed me because I tried it a week ago and it was running,
but now I know what she did before that test drive,
she took it out for an hour on the freeway so the RPMs would catch
during when it idles....

it was forutunatley under warranty, unfortunatley they were an Santa
Monica Acura dealership, and knew nothing of Mitsubishi Eclipses..
i took it in, and of course, they changed the 'idle valve' which is
the same thing she changed on her papers prior about 2 times,
a week later it was doing the same problem,
either I would start it and it would die (unless my foot was on the
gas) or I would come to a stop while city driving and it would
flucuate from 0 to 1000 then drop to 0 and die (unless my foot was on
the gas)
so i took it back into the dealer and they changed the 'idle valve',
yet again, and I knew myself that this would NOT fix the problem,
frustrated by their lack of professionalism and care took my car, and
to this day have been forced to work with the problem,
when it comes around I keep my foot on the gas and the break when
idleing.. at times..
it usually works good when I have a full tank with the best gas for
about 40 miles or so, then after i don't use it for about 5 + hours it
will come right back,
or go away for a week and then come back,
it is a haunting and daunting thing that keeps teasing me,
I really,
really, really, really, really, really, really, really, really, would
appreciate any help or knowledge or information you might know about
this... other than "change the idle valve" ...
and if this has to do with cleaning,
can i do it myself?
if so,
how?
thank you so much from the bottom of my gas tank!!

 

I don't know much about how the Neon engine controls are set up so I can't answer your specific question. However, I can make a suggestion to you. Scroll down the forum home page until you come to the Neon section of the forum. The people that are most likely able to answer your question hang out there. If you post your question there you might find an answer or, at least, some suggestions for you to try. Good luck.
