Alright well, update and need some help. A few months ago, I dropped a JDM h22 in my 93 vtec, and after I went through hell getting it in, its been having a problem idling.

At the very first start up, definate problem, my mph's were climbing and my car rev'd rediculously high. Then I replaced the TPS sensor, problem solved...or I thought. A little later, I can't remember when exactly but I think it was around the time I put my V2 intake on...it started idling from about 1200 to 1600-1700 over...and over...and over. My friends told me it was the MAP sensor, but at the time my check engine light never came on.

So I replaced MOST of the vacuum lines just in case, and replaced the intake manifold gasket. Then eventually, it would start revving as soon as I would start my car, and the only way I can get it to stop (besides driving) would be to put it in gear and let off the clutch until it just barely grabs. So finally today I get another MAP sensor. I put it in, no check engine light...and my car is idling fine, and little high...about 2100 or so, but alright.

Then just to check, i hit the throttle from under the hood, and as soon as i let off, it starts idling the same way again. I noticed one of the hoses I had replaced had slipped off, and put it back on. After that, it was back to normal..so I take it on the road. As soon as I get to the end of my street, it starts again.

One of my friends used to own a '91 civic hatch, and he had the same problem and said it turned out to be the rotary button on his distributor, and that fixed it. How do I know if mine is broken? Could that be it? Could it be that when I put my JDM engine in, I used my external coil (JDM's come internal coil) and old distributor?

Alright well, update. I cleaned my IACV, again...and that made it a little better. But when I took it around my neighborhood for a road test, it did fine...until it got warm. It started idling funny again...but when I pulled into my driveway it wasn't doing it anymore..

EDIT: Aight...now it's just pissing me off. When I went back out to drive...it went back to doing the same thing. So lets recap...
-New TPS sensor
-New MAP sensor
-Cleaned IAC valve
-Replaced vacuum hoses and sprayed for leaks

Still no luck...same thing

Another update..well triple post but no ones really helpin me out and I need it before I possibly make a huge mistake.

I read the write ups on how to change the EGR ports and all that. Well...when I drilled through, I'm pretty sure I drilled through the old plugs, so in order to get the new ones in I used a lil JB weld to line the holes I drilled, and set one of the caps in. Obviously I did it too soon because the cap sunk in and disappeared out of sight. So what now? theres pretty much no way I can get that out now right? Do I just need to get a new IM and save me the hassle or what?

First thing to do is search for rough, erratic, surging, and bouncing idle on here.

Because you're from Maryville (I grew up in Chattanooga) I'll give you my secret. Anywhere you suspect there could be a vacuum leak, spray it with carb cleaner with the car running. If it tries to die when you spray on a certain spot, there is your leak.

I actually visit there from time to time...just so I can have an excuse to drive the lude haha. But I've searched, and I've tried just about everything...literally that anyone has posted. I've went through pages of searching and everyone's got a different solution but none seem to work for me. My last hope was the EGR...that was the only thing I HADN'T done, but I'm in the process of it now...just have to figure out how to fix my screw up.

I accidentally drilled the holes too big on the ports and now I have to figure out how to get the port caps back in without them dropping straight into the manifold.
