(91 integra ls auto) my idle always jumps from 1k rpms to like 2 1/2 rpms when its either in N or P...do i need to adjust my idle or something else?

 

could be a vac. leak

 

idle air valve needs replacing maybe....does it throw any codes?

 

doesnt throw any codes...but micheal was telln me maybe the tpc sensor or the idle air valve.....can it lead to a serious problem soon or something not to worry about for the time being?

 

throttle position sensor you mean??? it wont lead to anything serious no besides an annoying idle

 

do you have any dimming lights or anything like that? Could be your alternator going out, or a bad ground somewhere, both of those happened to me.

 

I have a 94 integra gsr and it is doing the same thing. I've been going crazy trying to find out what it is, so if yall find out let me know

na no dimming lights..other then when i signal right my top left blinker blinks

 

its probably an electrical problem...iacv.. id start with the iacv

 

Could be the tps or fast idle thermo valve. I changed my iac and that wasnt the problem. Most likely its the fast idle thermo valve since this works when the car is cold and iac works when the car has reached normal operating temp.

Anyone is welcome to correct me if im wrong.

 

I'd make sure your coolant is full and you don't have any air pockets, my next suspects would be the IAC or TPS.
