I really need some help
#11
Ok guys I made some progress. I did some reserch and I was able to access the trouble codes for the JDM, and got code 45 ....Charge control. Does anyone if this would trigger limp mode. Also is the charge control a common problem.

wouldnt hurt to check the map sensor. vaccume line blew off, maybe cracked line or bad sensor. u could check the sensor manualy with a pressure/vac handheld pump. if im not mistaken you check them with hertz. you should see a certain amount of hertz with the varring pressure being monitered by the sensor. you can also check the ohms of the sensor but most time that wont indicate a bad sensor unless its an open curcuit or close to it, in the mega ohm range. you will need a dvom to check both the hertz and ohms of the sensor. good luck
the code u pulled could also be unrelated to the driveability issue you are fighting

He did pull a code 45. The charge control will put him into limp mode which is pretty much what he describes. As long as the manifold sees vacuum the car will start and run fine. But no ignition advance or fuel if the manifold sees positive pressure.
My is bet still with the charge control.

With a vacuum line cracked or pulled off the map sensor, the car would barely idle if it started at all. I know...like some others I accidently knocked that line off once. Scared the crap out of me until I figured it out.

im just going off how it affects my car . i can pull the vac line off the sensor on my car and it will idle fine just wont accelerate and runs extremly rich,
it also runs on an ems and is far from stock. it still is not a bad idea to check the map , along with the charge control circuit. the solenoid should be bench tested to see if the solenoid can hold a vaccume on the inlet side with out leaking through, you can also manualy give the control solenoid power and ground to see if you can hear an audible click which would indicate a functional solenoid.
