What would cause high EGT when I'm at idle? At idle it would be 250*-300* when it's running good, now it's @ 400* at idle.Cruising at 3rd gear 1500 RPM and 35 MPH it's @400* when it's running right.If i get on it it rises real fast and takes along time to come down.A minute later it's normal again,could this be an injector issue cause is rumps for a few seconds like there is extra fuel dripping from the nozzles.I tried to pull codes but there were none.

 

Also the exhaust odor is very strong at idle.
