          PROBLEM SOLVED!

          Thanks to N A on here, I got a Lightning EGR spacer installed, and I installed an HO throttle body.

          Put it back together, hooked it all back up using the Mustang IAC with the plug inverted and vavooooom!

          Car idles like STOCK

          I also gained at least 1,000RPM before it shifts now too, which is kinda freaky. I don't know if its pinging or not, kinda sounds like it, so I may have to switch back to high test, or, it could be the insane carbon build-up from it running so rich for so long.

          In any case, it runs like a TOP!!!!!!!

          Thanks for all your help guys and a special thanks to Gadget for hooking me up with N A.

              Oh man, its SUCH a relief. No "racing" going on, but I know for a fact that the TC, with stock gears and the conversion is now substantially faster than an "Extreme" S10.........

                Sweet dude! I have a 1989 HO converted towncar as well, except I wish I had explorer intakes and 1.7 RR heh. I had the same problem with surging as you did, then Scott and Thain dropped by and found that my EGR wasn't sealing to my intake!! As soon as I fixed that it idled "like stock" as you said. Sure is fun beating on ricers with a big old Town Car heheheheh.

                  Man, the look I got from the guy in the S10, I could NEVER get that look in the Capri or the Mustang because well, its a Mustang. There is, even by the ones that "think" they are "fast" some voice in the back of their head that puts up that "what if?" sign when they come across a Fox.................Now, a huge silver boat running on turbines, well..........There no CHANCE it could be fast, right? HAHHAAHAHAHAAHHHAH I literally broke out laughing man, I couldn't stop myself, the look on his face, well, it was one of absolute dismay and astonishment all rolled into one......truly priceless.

                  I didn't "race" him per se, he gunned it away from the lights, so I just kinda hung with him, he floored it, I hit 'er, pulled away from him, got about two cars on him, and then let off, and the look on his face as I went by him............ Never exceeded the posted limit

                      sweeeeet! oh man the other day, I was at a light and a yellow mustang pulls up with some 16 year old and his buddy inside, cranking their crappy music. I had a feeling they would gun it off the light so when it turned green, I floored it and he floored it....the look on their face when I started pulling away was priceless...priceless I tell you hahahaha. It was a 2004 or so V6 auto, I doubt I could hang with a GT, at least until I supercharge this beast!

                        the lightning EGR spacer is Required when you run an Explorer or GT-40 intake, the stock (bored out) EGR spacer simply wont seal and it ends up leaking vaccum into the back side of the spacer.

                        BTW... I have run my ACT sensor in both the stock location and in the fresh air intake. Really dont notice a difference either way.

                          My stock EGR spacer wasn't bored out, the sealing area was minute (like 2mm) though, but after I used a Mustang EGR spacer gasket on it the last time, it didn't LOOK like it was leaking, but I'm sure it still could have been.

                            Just be careful racing people or you'll end up doing a heater core like I did. Install some washers on the feed hose to the heater core to act as a restrictor. Trust me, heater cores on these aren't fun, and they're less fun when the core is swelled up from operating at ludicrous speed for extended periods.
