I have a 1984 CJ, a 1989 YJ, and a 2005 Liberty, all used regularly off road.
Daughter has a 1999 TJ.
I just installed the Howell EFI package in my 1989 YJ, and am having a problem getting it smogged. 2 Different Smog Check stations say that I'm too rich. Howell says that the only way that that can happen is a bad spark module or timing. I replaced the spark module and checked the timing for 8-degrees btdc, and it still failed!
Any ideas? ( Oh, yeah. The Jeep runs better than new, better fuel mileage, better power curve, yadda yadda!
Just won't pass CA Smog!
