Well I hate to bother but I have a 94' Honda Accord Lx.
It had the erratic idling problem when started and then when I went to drive it, it would jump from about 1200-2k rpm.

I had cleaned the IACV, Adjusted the FITV, Cleaned TB, Cleaned the EGR Ports, Sprayed Carb cleaner on majority of the vacuum lines then taped them up, Changed spark plugs, and changed my ignition switch.

My car is still doing the same thing. When first started up sometimes it will rev at 1k RPM, and then jump to 2k RPM then go back down to 1k.

Then when I drive I'll hit about 1200 RPM and it will instantly kick to 2k and go back and forth between that until I pass 2k RPM.

I also learned that when it idles and I turn on my headlights it will go below 1k sometimes.

I also learned that there is this little box (I'm guessing it is the MAP sensor but I didn't want to assume), located on the passenger side by the TB wasn't ticking, so I unplugged it while my car was on and plugged it back in and it started ticking (like electrical current popping through it). It ran fine with the CEL on after doing that. Could that be one of the problems to why my idle is acting up?

Someone also claimed a bad TPS could be the problem to it too but I'm not sure where that is located nor do I know how to test it.

So if anyone could help me, I'd greatly appreciate it.
Thank You

 

Have you checked the PCV? Also, sounds like you "set" a code when you unplugged whatever it was-was there any codes before? Check the codes-you set one so?-then reset ecu. See if any come back.
