Turkeylord Posted November 17, 2018 Share Posted November 17, 2018 Ugh, just passed 3,000 miles on this build and already problems... Taking the ol' lady on vacation and having issues. So it's been having issues throwing knock counts, especially when cold, but it was no where near what it's doing now. It was behaving well for the first 3 hours of our drive, then I stopped and filled up with more e85 and got a car wash. I only mention the car wash because I never did replace the splash guard under the engine, and maybe there's a chance something got wet? Anyway, a few miles later the DAM dropped to 1.125 and it started counting TONS of knock. No roughness on any cylinder, oil pressure is good, and the AFRs look ok. Any ideas? I'm scared to drive it, but we're 4 hours from home. datalog25.csv Link to comment Share on other sites More sharing options...
SBT Posted November 18, 2018 Share Posted November 18, 2018 I've been running without an undersplash guard for years, both in SoCal and in SoCar through cow-peeing-on-a flat-rock hard rains, and weekly car and underbody car washes with zero issues. Sounds more like bad E85... - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
relative4 Posted November 18, 2018 Share Posted November 18, 2018 I'm in for a tank of bad gas. Oh shoot, missed SBT already said that. Link to comment Share on other sites More sharing options...
kzr750r1 Posted November 18, 2018 Share Posted November 18, 2018 Funny that. I've been seeing a bunch of swings in DAM and watching learned knock on the monitors lately as well. Just placed the primitive pan back on the car. What was interesting for me is it's the first time I've seen DAM drop significantly and recover within a mile or so. Is DAM staying at a lower than expected reading all the time? I'm going to start looking for misfires next drive. EDIT: Noticed after commenting your log. That would freak me out too. Keep an eye on her. Fuel up with some fresh petrol and see if it clears before freaking out too much. Now off to go look at my last drive log since the AP is in the house at the moment.

Turkeylord Posted November 18, 2018 Author Share Posted November 18, 2018 On the 05, which fuel line is the supply, and which is the return on the intake manifold? Link to comment Share on other sites More sharing options...

Turkeylord Posted November 18, 2018 Author Share Posted November 18, 2018 Woof Got it down to half a tank and fill back up with fresh 85. Added one bottle of isopropyl alcohol in case there was any water in it. Still doing the thing. Link to comment Share on other sites More sharing options...
kzr750r1 Posted November 18, 2018 Share Posted November 18, 2018 Weird the DAM is still 1.0. You don't have a 91+ map and change fuel? Link to comment Share on other sites More sharing options...
Turkeylord Posted November 18, 2018 Author Share Posted November 18, 2018 Forgot to mention I did recently see you when I put the new 85 in *edit* dang voice to text. That was supposed to read “recently reset the ECU when” Link to comment Share on other sites More sharing options...
Turkeylord Posted November 18, 2018 Author Share Posted November 18, 2018 Made it to the next stop on our trip. DAM stayed at 1.000 for quite a while. Eventually did drop to .500, then recovered back up to .750. Seemed to run pretty well, but we were just cruising at 70. May try to get it into the local Subaru dealer here in the morning.

kzr750r1 Posted November 19, 2018 Share Posted November 19, 2018 Hoping for the best. Frustrating for sure because you spent some time as I have doing your best to keep it together. Really curious how this saga turns out. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted November 19, 2018 Share Posted November 19, 2018 What are your long term fuel trims? Link to comment Share on other sites More sharing options...
Turkeylord Posted November 19, 2018 Author Share Posted November 19, 2018 Is that something I’d have to look at in a learning view? Or can I wiew them in the AP? I’m really rusty on all this stuff. Link to comment Share on other sites More sharing options...
Turkeylord Posted November 19, 2018 Author Share Posted November 19, 2018 Called the local Subaru dealer this morning, they said as long is the check engine lights not on it’s not a big enough problems to come in for. <shrug> Link to comment Share on other sites More sharing options...
xt2005bonbon Posted November 19, 2018 Share Posted November 19, 2018 Yeah. You can pull a learning view or you can find this info in the AP too. It should be called like AF learning A/B/C/D, something like that. Link to comment Share on other sites More sharing options...
Turkeylord Posted November 20, 2018 Author Share Posted November 20, 2018 Made it home! Car did eventually throw a CEL for Knock Sensor 1 Circuit High Input. Maybe just a bad sensor? A guy can hope... Link to comment Share on other sites More sharing options...
cryo Posted November 26, 2018 Share Posted November 26, 2018 yup my guess is a bad sensor...
