I just got my car running after my recent mods. I just put gt40p heads and headers, trick flow track heat intake, 70mm tb, and e303. I got everything back together and got it running pretty good. The only problem is when I try to lower the idle, it will run beautifully until the idle dips below 900 rpm and then surges till it stalls. I was having bad idle and surging issues and I replaced IAC, ect, and air charge sensor. These all helped tremendously but I can't get over this last hump of making it idle below 900. Thanks, Casey.

I switched to 19 lb explorer injectors but kept stock maf. The car will idle fine at about 950 to 1000 rpm, but if you take it up the road and knock it in neutral at a stop sign, then it shuts off and is very hard to crank it back up.
