i have a 91 se-r with the bluebird swap in it. i have a serious problem. when i start the car, and when it heats up, i cant push the car past 5000 rpms without it cutting off when the RPMs drop. ive had many ppl mention things to me such as the IAC valve could be messed up. or a vaccuum leak. someone please head me in the right direction :banghead:
