ECU issues are always frustrating. Glad it wasn't anything serious.

I won't be at the races today. My guy from work couldn't get his wife to let him race, and I have too much stuff to do at home. Maybe I'll make it to the next one.

Sent from inner space.

So are you gonna race this Sunday?

I may be bringing my fam to watch a guy I work with drive his C-prepared mustang.

Thanks guys, I will check that next. Also I dont know if it makes a difference to you guys, but mine actually seems to do it worse when the engine is colder, and it will also do it at light throttle. Like cruising around town in third gear, very light throttle, it will miss bad as well. But thanks again for the suggestion, I will check it soon!

Sounds like your issue is probably being caused by one of the more typical causes: plugs, coils, injectors, maybe even valves (I'm saying that one just for bonbon:)).

What makes my problem unique is that it happens/happened(?) only at zero mph, and rpm/temp don't seem to make a difference. Many of the things I've tried can be ignored most people. The cause of what makes me unique (as heiche mentioned) hasn't been investigated yet... but you can see the effects in the few threads I've started.

Holy crap, what is that car?

A quick little bit of yagoogling and the short answer is Lexus LS400 (and Toyota Camry?).

The search function on here isn't the best, and I think most of us use Google.

Try something like this (question, followed by "site:legacygt.com")

The first one that came up seems like a good idea

I ran into a huge issue on Friday... the motor stopped misfiring.

Not on the way to work, not on the way home, and not on Saturday.

No joke, it just stopped.

Is this car trying to push me over the edge?

Could the car sense that I'm getting close to the root cause and it temporarily suspended the symptoms just to play with my emotions?

Is my car Herbie, reincarnated?

The new (used) fpr will stay in my toolbox until the misfires comes back.

Raise your hand if you're confused and frustrated.

Whaaaaaat?

I'll definitely be watching that to see what it ends up selling for.

Right now at only $12.5k it would be a steal.

Update:

I threw more money at the car.

I bought a used STI fuel pressure regulator.

Right at this very moment it's in my garage waiting to get installed into the most awesomest 5-speed LGT wagon in Kentucky.

If we have good weather I'll do the old swap-a-roo this weekend.

End of update.

I'm glad to hear it's back up and moving.

No flex sounds a little concerning but it probably wouldn't have crossed my mind if you hadn't mentioned it.

Unsolicited advice:

For the exhaust wrap, buy a cheap pair of long-sleeved rubber gloves and use a bucket you're ok throwing away afterwards. That stuff sucks.

Stainless zip ties are really cool if you've never used them before.

Clean it better than anything you've ever cleaned before, and spray light coats.

JMP paints his turbos so I know it's doable.

Nicely done.

While it's apart don't forget that painting the housing makes your car go faster.

Oh yeah, just noticed that.

Want me to take that bolt out of my turbo for a few days and see how well it stays sealed? I'm only partially kidding.

Just go a little bigger.

Heck, using the freshly non-threaded hole with a longer bolt and a nut would probably work fine. The other bolts/studs will be enough to keep the turbo aligned properly with the DP.

Both of you can just shut up right now and take your stupid shortblocks right back to where you found them.

Leave the the BtSsm though, that still works great.

Yes, it's consuming+leaking about 1 quart (total) between changes.

About half to 3/4 of that is probably consumption.

The injectors aren't new, but one is new to the car. The misfire is semi-always in cyl#2, and swapping the injectors around to different cylinders doens't change anything. I've also cleaned them in my ultrasonic cleaner.

The in-tank sock is new, the pump is a almost-new dw65c, and I don't have an engine-bay fuel filter.

The miss happens at 0mph regardless of RPM (700, 3k, bouncing off the rev limiter), in and out of gear, clutch pedal in or out, brake pedal in or out, so would your PW/DC theory still apply? At 0mph on a hill it misses, moving >0mph it stops missing (forward or reverse... I tried it).

I haven't messed with the PW/DC at all since I started tuning so it's worth a shot. The misfire started on the 100% stock tune so I'm not optimistic.

I'm a liar... I'm optimistic and I get a little excited about every new potential-fix I hear. Roll the window down and turn the volume knob to 100% with the stereo turned off and the passenger seat heater at 50%? It's gotta work, I'll try it today!!!!!
