I am having an intermittent issue with the motor for the past few weeks. I have done quite a few things trying to chase it down, getting ahead of myself, I did a few things at a time. Although it appears to be getting better it is still happening, and I am unable to put my finger on exactly what it is.
I am going to try and keep the posts in the proper area, so I will do each system seperately, but reffering to the same issue.
I originally thought it had to be fuel but it could be ignition or maybe even exhaust system?
The Issue:
Motor will randomely, sometimes right away and sometimes after running for awhile, act like it loses all power like the igntion was shut off, fires sporadically and then starts running again. every once in a while it will die long enough to stop, motor will have to be started again, which it will usually fire and run again.
In this post I will try to focus on igntion system, although I am leaning towards fuel, I will try to explain that in a seperate post.
I have early model prestolite distributor with indigo EI around 10-15 yrs. old.
While trying to chase this down I have replaced alot of things thinking if it doesnt help I will have a good spare.
D-cap, rotor, sprk plugs, wires, coil all replaced to nothing more than a slight change for the better?
All parts replaced are from MMI.
I do have the manual, and all the videos, and have read and watched them many times so I am not completely in the dark.
One thing I discovered is that the rotor from MMI does not work on indigo e.i. I noticed that p.o. had shaved down the head of rotor, and I was able to do the same.(will add pic) very strange, where do I get the proper rotor? not listed as an option on Indigo website.
Do u think this system could be malfunctioning in some way? The e.i. starting to go bad, the controller? box of indigo set up overheating going bad? (pic). Like I said I am leaning towards fuel but want to take on one system at a time. will add pics to show my distributor etc.
I have used a jumper from starter to coil to bypass the boats system and it still did it, checked all the boats system still an issue. When it dies i lose only rpm all other gauges are still powered. where am I on the ignition side of things? All spark plugs hot, and when its running its running good. only the intermittent loss of power and rpm.
I am going to start post on fuel system where I have also done quite a few things trying to chase this down. Thank you in advance for any advice or help.
