2001 Chrysler Neon with high Idle RPM
Hello everyone.
I have a Chrysler Neon 1.6i from 2001.It´s been a great car, until a few weeks ago, when I´ve started notisting the idle getting higher then normal.
At the same time, the engine light turned on since then.
Now, it idles at around 1200 rpm, and sometimes it gets to 2000 rpm.
A mechanic friend of mine used it´s OBD diagnostic scanner, and it gave four OBD codes:
P0507
P1654
P0181
P21211B
What could this be?
Some of the OBD codes are codes that I could not even find any definitions for them.
Any help would be highly apreciated.
