Im getting a code that reads on my power vision that says EFI idle problem . I had an injector go on the weekend and replaced with one a friend gave me . I thought it might have been the short injector harness so I soldered in a length of wire. but to get the wires short enough I had to take apart and solder right to the conections . so I might be having a problem with the injector harness conector shorting out . It also surges on throtlle. Would this give me a EFI Idlle problem code ? Thanks F.K.
