Recently got an email tune from mailordertuner and Im having issues with the throttle body being really sensitive and preventing the car from starting and idling. Ive managed to get the car started on occasion, but nothing concrete and consistent and usually if starts once it wont start when its warm. Recently I was able to get the car started when I adjusted my TPS to 4.3% and decided not to reset it. Got it to start and run but once it hit closed loop it started running rough so I killed it. Since then I haven't been able to get it started. Ive been chasing that 4.3% but still no dice. Often I get it to fire for a quick second and then it just dies.
I've used different TPS sensors and IAC sensors but still no dice. Casey from mailordertuner said to set the IAC at 60 once its warm but I don't really know how to and it sits at 310 cold which I heard is normal.The lowest I've seen is about 170. I've been hearing about people drilling out the IAC hole. I'm beginning to think that is my only option.
Gonna give Casey a call and see what he says. Im not too sure if its a tune issue or a tb issue or both. What do you guys think? looking for as much info as possible. The sooner I can get this car running the better :)
Appreciate the time
