I am getting ready to buy that housing from olypy parts. Should I just have my mechanic install it since it sounds like you really need to know what you are doing, and need to fully understand the KE injection system? If it was just a drop in and screw thing I could do it but when it comes to electronic diagnostic equipment, etc. I am lost. I had those same symptoms as the starter of the thread had so I believe that this will probably solve the problem.
