High idle in park and neutral, sporadic idle in gear
1998 jeep xj auto with 4.0l when cold it runs fine once it warms up in gear it will rough idle up and down then when put into park or neutral it revs up to 2000 rpm has a lot of cel codes but has had them for a while. This problem started after i degreased the engine on the driver side i did not spray the intake though.
