first of all you some of your readings are off. BLM'S should be close to 128 as possible = or - 10. your at 152 which means that you are running lean meaning vaccum leak or ekhaust leak. your IAC should be around 15 to 25 fully warmed idle. also you need to check and see if you are running a 160 thermostat. get those numbers close as possible before running it hard. you may want to get a chip from TurboTweak Home they are the bomb your car will love it. also do a spring cleaning wwwgnttype.org
