ok so as its getting colder out i have been having idle issues. 1st that car is modified along with a tune and sometimes hunts for idle and has been doing so since i have owned the car. now the issue when u start the car it starts then dies. i have in the past few days been able to simetimes start it cold or hot and its fine some times i have to let it get warm then it will idle.. so i checked my tps volts there a little high but have been so for over a year .95 closed 4.50 WOT. i also replaced my IAC now heres my first question it was far out when i put it in but gave no resistance when i tightened it is that wrong or damanging or is it ok to do? i beleive i followed the instrouctions on here pretty well. but i am going to try to reset it again 2moro. my second questions is what else can cause this? i can affored to replace everything or have the time im hopeing someone just hits me with the right solution. also car dose have a vac gauge and i dont see according to the gauge a vacume leak thanks guys!
