I did a search and foudn nothing, so What is a good idle point? Right now my car idles at about 900, but sometimes after I slow down and am sitting at a stop light it will idle at 1100.... also sometimes ill be at like 4k in second and Ill let off the throttle all the way and it drops to like 2k orso and stays there for a few seconds... I want to know if this is normal or if this could be related to the codes i got the other day which were p0335 and p0068 ... after i ran the scanner at schucks my check engine light came out.... but it feels like the car is "high strung" now... like it wants to stay at higher rpms.

I had idle problems. I had to clean my throttle and my Intake Cone. it would bounce from like 700 to 2000 all the time untill i did that. but u could be have some other kinda problem, its worth a check though.

 

I'd say check your throttle body, make sure its clean.

 

Crank position sensor and throttle position sensor.
