i am having very low idle at start up and throttle response is lagging. As soon as i go to crank the car it idles around 400 or so and stalls there then after a while it will idle fine. Even while driving, as i approach a stop or go to slow down and put the car in neutral, my idle will drop all the way down as if it is going to turn off. Sometimes it i will recover and idle fine and other times it stays down low. When it stays down low i try to give it throttle and it does nto respond. it takes it a few seconds stepping on the throttle to get it to respond. There are times where the car is running fine, then times were the idle drops really low, then times were it just shuts off. There is no consistant pattern as to what it does. I am currently running a 75mm TB, bigger plenum, hitech stage two cams, CAI. the car has been dynoed and tuned about 8 months ago. any suggestions or ideas?
Thanks.
Thanks.
