Hey guys so school is right around the corner and this car is road worthy once again, but I can't drive it without killing it. Each time I start it, I have to flutter the throttle very quickly until it reaches 800RPM or more and it will naturally catch it's idle range and idle like a kitten. When I go to rev it I have to get out of the cab and millimeter the throttle body by hand or else it will die if I give it any more. It does rev high once it's going then it idles back to 1k without any problems.

Just wondering were I should start looking, rather if it is the TPS, MAP sensor or vacuum lines.

I did find a great how-to guide on how to set the TPS - http://www.mk3supra.org/topic/56-guide-setting-up-your-tps-throttle-position-sensor/

try unplugging the tps and see if it makes a difference......I believe unplugging the tps causes that issue with the throttle
