Ok guys so I have a 97 civic ex with a d16y8 in it.. my car is idleling weird when I start the car it isles high then it calms down to around 800-1k but when I'm driving and I come to a complete stop the idle goes up to around 1800 and slowly comes down back to normal or sometimes I have to step on the gas and will come back down I have taken my iacv out cleaned it and aired out the coolant but still does it I've also herd it can be the TPS but Idk wanna get some feed back on what I can do b4 I do anything else to it

Check for vacuum leaks and there still could be air in the coolant get the front end higher than the rear and idle it for awhile, it can take multiple times to get it out I would start by checking for vacuum leaks though

I second checking for vacuum leaks.

Check that your pcv is working and that the brake booster check valve is working

Ok I'll check when I have time... Also when I'm driving and the car is on normal idle and if I was to move the steering wheel the idle will pick up and slowly go back down

Also, you need to check for trouble codes.

the idle should pick up under load but only 50-100 rpm depending on how much load as it is stated in the FSM I don't think its supposed to go over 750-800 though on its own
