Hey guys, so I have an issue with my 90 SC. A while back it had this issue that the rpm gauge will drop to zero on the highway and it would cause this bucking senario. Once in awhile when I was at a light it would die and it would take a good three minutes of cranking to start and after that it would run fine. So searching through the threads here I found it could be the cam sensor or the DIS module. I have now changed the cam sensor and my bucking is halfway gone, so to speak. It now seems to jerk and I haven't seen the rpm gauge go to zero. The jerking seems to go for about a good three to five miles on the highway. So now I am stumped as to what it could be. Could the DIS still be bad or the crank sensor? Any thoughts are appriciated.
Thanks in advance.
