I heard there was a little mod you can do to help your rpm's from hanging for so long. I know it has something to adding a gasket or piece of metal with a smaller hole in it, to the IAC, i think.......I may be way off so can anyone ellaborate?

im not sure what it is but do a search for iac mod and see if it comes up ive seen threads for that alot but it is what your explaining

yea you have to make a gasket with a smaller hole in it to restrict some of the air from the IAC

You can also have it tuned ask your tuner about setting the dashpot.

i saw my buddy do it, he used a really thin piece of aluminum. use the iac gasket as a template and trace it onto the sheet metal (including all the holes) and cut it out. you might have to do a little trail and error to find the ideal size for the air hole so it lets in just enough air but not too much

pretty much makes the idle behave like a carbureted idle I'ma gonna do that to mine eventually

I think i will order that one off od ebay.....seems like it would cost close to that to buy gasket maker, and make it myself.

I just hope it will work with my car.
