Hi F-Chat - Wondering what it would take to refin the wheels on our '84 308. It looks like they were done poorly in the past, and if I...
Hello guys, been a while and here is the update: As I said weeks ago I ultimately discovered by looking through the RPM sensor port that one of...
Well, I found the problem. I decided before swapping the sensors that since it's fairly easy to remove the RPM sensor because of its location, and...
John, Yes, the are Magneti Marelli. I found them on Amazon (link below). I cross checked that were the same ones - SEN8D, part number 119052 -...
Correction- TDC sensors…. Not TCC..,,
Thanks Steve, I checked both coil's ground, the 3 ground pins at the diagnostic port, the digi ground, (the point you indicated in the picture)....
Yes I love that that’s actually “good” news. The thing I am dreading though is a flywheel pin problem because that’s a lot of work. Can you tell...
Well, mine look nothing like that at all. Here's the videos from bank 1-4 at 5ms and 10ms. (Bank 5-8 look similar. I will post those too later...
Ok good plan. Thank you. I will test TDC sensors signal at 1K RPM also.
Ok I'm back already and was able to snap a photo of the scope at 1000 RPMs. It is indeed about double the time between firings compared to your...
That’s a great catch. I can’t confirm exactly what I was idling at, so I will test again and match the 1000 rpm’s and see the reading. I did just...
John, Thanks you for taking a look. I really don’t know what the problem is but based on all the comments it seemed it was a good idea to once and...
I'm back with some scope videos per John's specs. (Btw I'm pretty jealous of how good your engine sounds, John.) I tested bank 1-4 coil trigger...
OK got it, my next garage session, (likely end of the week) will include the Shadetree test and getting additional scope readings including on the...
Thanks John, I tried 1-4/TDC again on with a faster time and got this result. (link below). I'm curious to see what your settings and readings...
Good Afternoon. Steve and John, I hope you are still following along, I very much appreciate it... and everyone else's advice too. I finally...
Thank you both so much. Makes total sense to me now in terms of how it's all wired and where to test. I'll report back with results. Johnk - I...
I purchased a $36 oscilloscope.. I’d like to confirm where the scope’s leads connect to– I’m not clear on this yet… Do you disconnect both the...
This is what I thought too: that if it were the RMP sensors, or the digiplex boxes, then the issue would follow to the other bank when swapping...
Yes, I had done this and do have good connections from cap to plug wires but still problem exists.
