I'm having a strange problem with my 1986 305. I've been having problems ever since summer started. it dont start so well, even after its been warmed up. ever since its been feeling like the engine has been "power surging" slightly. it was hard to tell at first cuz the roads around here are so bumpy. but it got alot worse yesterday. it sounds like it misses. I guess my questing is, do I need a new module? or cold it be just the plugs? or maybe even the coil?
