Got my car back form have 97 JDM B18C swap. Im having 2 problems that I cant figure out. My cars idle is bouncing from 1000 to 1300 rpm. Sometimes it stays at 1300 other times it bounces, like when I make quick stop. Problem 2 is my speedometer stopped working. Had them check the trans speed sensor wheel which is fine. Can this be caused by a blown fuse. Im using my GSR throttle body that was ported to 62mm, for ease of install. So you guys know Im temporarily using stock GSR computer till Kenjis setup gets to me. So is this ecu related or fuse or what? Please help because this is beginning to really annoy me. TIA

 

Well I figured one thing, when you do a test drive at night and car shuts off after a few minutes, I must have a short. Now the car is in garage and wont start. It seems to idle allright, now just wont run. Guess I have a short. None of you type r gurus have ever dealt with this kind of crap. Someone, anyone give me something to go on. Please!
