I have a 98 ex AT, it has always had an erratic idle some days little high some days a little low some days perfect. but lately after putting it in park the idle will go up to 3000 to 4000 rpm and the shifter will be locked from moving. this mostly happens if it is on an incline. Has anyone seen this before and if so is it air fuel issue or is it transmission. history of this car is it has 260k. it is regularly maintained (oil, filters, plugs changed to schedule) few months ago the idle control valve was replaced with genuine Honda part, this helped a lot with idle at the time, I could run the a.c. at stop lights with no issues but didn't do much for vibration at idle. meaning idle is steady but car vibrates. Direction with high idle issue would be much appreciated .
