Just got back from Prince Edward Island of a week camping. On the way home my 1988 2.2  digifant  engine started to hiccup only at 3300-3400 rpm in 3rd and 4 th gear. It did this 2-3 hiccups at a time not just one as the typical digifant syndrome does. It did his all the way back to our farm. I have the correct harness on the AFM to correct for this. My thoughts where the coil or the AFM must be going. Weird that it only happens at that RPM!
Does anyone have any ideas what I should be checking ?
 We would like to travel back to Quebec Canada soon.
