Quirky Ignition system

[Mosebrosdsm]

So basically got the 97 eagle talon tsi on a little road trip. I’ve taken this car on 8+ hour trips with no problems. Sorta broke down a couple times having a weird electrical issue is what I think. Not sure tho. Basically doesn’t matter if it’s in town or cruising everything is running great then bam the revs drop drastically, rpm gauge will show different rpm range than I’m in. Bogs way hard like there’s no spark. But there is just at around 1/10th the power. I replaced the coil pack with one I found in this town I’m stuck in thinking that was the problem since that’s one of things I havnt replaced on this car yet. Got about 100 miles outside of Billings and started doing it again. If I let us sit a couple minutes it will start right back and I can keep driving for a while then it will do the same thing gahhhbh. Also I keep pulling up the same DTC a multiple random misfire code. I’m stumped I’m really lost. And I’m also stuck!! HELP!!

PTU taking a dump?

Otherwise I'd think cam or crank sensor.

I replaced the PTU around 15,000 miles ago. Not sure the symptoms lead to a crank or cas. It feels more like a short in the system. I’m gonna throw a log up later when I get WiFi today. Almost to Bozeman it acts up every 15-20 minutes or so then will correct itself. Really annoying.

Im currently trying to get back home to Logan Utah. I’m currently right outside Bozeman so if any fellow dsmers in Bozeman would like to lend some input I would greatly appreciate your knowledge!!

I'm not sure if it will help your situation. If you have link go under dtc tab an uncheck the misfire check box I can't recall exactly what it was labeled. Basically it skips that ecu test I think, but that helped me when i had a similar issue. I think it's more of a bandaid than a fix. Just trying to help out if I can thank you for your time.

Yes thanks for the help. And we got her running real good. There was a short in the Harness of the PTU once that was fixed there was no more issues! We went thru ecmlink and cleared codes and were back on the road in no time!

That's good man I'm glad to hear it. The age of these cars likes to rear up an show its face sometimes
