Has anyone reproduced these yet? Had to replace my coils and would like to replace the labels. Image Unavailable, Please Login Image Unavailable, Please Login
Fantastic! I bet this coil had been intermittent enough i didn't notice. Sent from my SM-G930P using Tapatalk
Awesome! I still tend to think that you were dealing with more than one problem but the important thing is that it's running right now.
I still think electrical was involved too.. those connections were bad. Sent from my SM-G930P using Tapatalk
We will never know, will we? Except nothing helped until the coils were changed. I'm just not one of those keep fixing things until something works kind of guys. My personal opinion would be that many of the things addressed were superfluous. Just an opinion.
The coils affected the miss for sure with the no spark .. but I didn't have the no spark when the CELs started. That started after i replaced all the sensors. Sent from my SM-G930P using Tapatalk
Based on my own experience with my car I'd have to agree. I thought mine were okay based on appearance, but cleaning them has made a big difference so far. I think there are still some iffy connections in mine, some of which may have to wait until the engine-out service. Judging by how much smoother/better it runs it's worth the effort though.
I certainly do not believe in just throwing parts at a car, but in this case there were a number of symptoms that did not really match up to just a bad coil. On my own car I've found that things may seem to be working okay, but replacing them and/or cleaning the connections to them has really improved the way the car runs and eliminated some gremlins. With German cars, when something is working that almost always means it's fine and does not need attention, but Italian cars seem to prefer more attention.
I cleaned everything I could get to in the engine bay. Also ECU pins. Working on all other connections as well. Used the D100 on my door harnesses and now my mirrors work again. Sent from my SM-G930P using Tapatalk
Same as David, only I haven't done the Motronics connectors yet and cleaning my door connector pins fixed the right side window instead of the mirrors. Still need to go back with DeOxit Gold contact enhancer after the cleaning though, to complete the job. I used Gold on the power mirror switch and was very, very impressed.
I wasn't about just throwing parts at it either. The initial CEL's the car was showing all indicated things other than no spark. The no spark issue didn't show itself until all of the CEL's were addressed. Those sensors replaced and in the order based on the CEL's reported: O2 Sensors -- didn't have codes on them but that's usually first recommendation I've seen when codes appear. They were due to replaced at major next year anyhow. RPM Sensors Cam Phase Sensor CTS Sensor I did not replace the T-ECU's even though they were storing codes. Even when the T-ECU were disconnected the ECU was recording a code. So that warranted a replacement of the EEPROMS based on guidance/suggestions from other folks who've experienced similar issues. I didn't realize non-oem chips were in the ECU's until I opened them. All of these replacement parts cleared the codes. Then the no-spark occurred. Could it have been intermittent all along? Perhaps.. but I didn't notice any performance issues. I added new plugs as some were fouled including the cylinder with no spark. Bought a spark tester and confirmed no spark on the ignition coil. All the other things I tested through this process can be garnered from this post (http://www.ferrarichat.com/forum/348-355-sponsored-bradan/517358-dreaded-cel.html) Replaced the Ignition Coils which cleared the no spark issue. So now no CEL's and no performance issues. Just cosmetic stuff with the new parts. I'm all for not "throwing parts" at a problem.. but I'm not sure how else I could have made this process more efficient and not put parts in the car based on the history indicated. I'm certainly open to suggestions and perhaps it will help the next 348 owner with their troubleshooting process. David
David, I don't think what you did was throwing parts at the car by any means whatsoever. Everything you replaced had given you some reason to suspect it. IIRC, you also had a CTS fault code, in addition to the others-- that's one I've never even seen on my own car. It's entirely possible that some of these codes were due to bad electrical connections but most everything you replaced was pretty cheap, and I'm betting the entire parts bill was less than the diagnostic charges if you'd taken it to a pro. I guess I should restate my earlier position and say that I'm not one for throwing money at a problem until it goes away. Because in some cases it's more expedient to just install a new part than it is to borrow or buy diagnostic equipment to test that part, or to pay someone else to do it. And that's especially the case if you just want to get out and drive the car instead of engaging in a drawn-out diagnostic adventure. IMO your path was a good one, even if it may not have been totally perfect in hindsight (not that Im saying that it wasnt). You learned a ton about your car and you installed fresh components in place of 25 year old parts. In the end you have it running again without having to pay a bunch in diagnostic charges. I'm pretty sure most owners here would be happy with and proud of those results. So good on ya!
