The last few days my 2000 AMIGO's cruise control has been engaging and disengaging on its own. Started only here and there now it happens all the time. I tried unplugging the cruise button on the left side of the steering wheel and it didn't help. I cant seem to find a fused any were for the cruise control either. I have read post's on other sites were people have the same problem but have not been able to find a answer. Also its really hard to start. Has been since I bought it a few months ago. Any ideas as to what could be causing these problems? I just changed spark plugs so I know that's not the issue with the starting.
