I think you should have the car retuned by a professional. Sounds like the tune isn’t matching up to the hard parts you have on the vehicle.

Me, I have a real problem with “safety features” that can kill you.

My Honda Civic went into limp mode while I was heading E on I-90 out of Seattle, just as I’d entered the Mount Baker tunnel prior to the bridge across Lake Washington. Two narrow lanes and no shoulder. I really thought I was going to die as cars entered the darkened cavern and suddenly had to screech on their brakes.

The diagnosis on my car? Nothing. No codes, perfect shape.

I don’t know. Can you think of anything that might have changed in that time? Parking it could just be coincidence.

Someone threw power steering fluid on the outside of the gearbox? Won’t hurt a thing. Just make sure it’s not near anything hot like the exhaust so it doesn’t smoke.

Did you mean they put the power steering fluid in the gearbox? Most power steering systems use automatic transmission fluid, which is the same stuff that goes in your automatic transmission. If this is the case, that is normal.

Could be. Sounds like a transmission problem to me though.

Limp mode isn’t a problem , it’s your ecm response to a problem it detects. So, it is saving itself from letting you destroy it, by not letting you drive. When you do any kind of service work on your car that interrupts the system like change out your solenoids mass air flow, ECT valve, air filters , oil change, your car must be reset to learn the fuel to air ratio in order to run proper idle trims. This is a variable that you can see when you use a diagnostic tool which you can purchase online or auto places. Obd 2 scanner. These numbers can tell a person whom knows how to understand the codes, lean rich, and check to see where your idle trims are at. Should be 0. You got a high and a low and they should level out to meet in the middle , sort of. Like -25 and +25 equals 0. Anyways, I’m sort of laymen terming it. But, it could just need a reset. Could be the mass air flow. EGR valve. IAC valve. Fuel injectors, filters, and pump. You could just need transmission fluid. Or worse, you’ve got a vacuum leak. Get the code scanner. Look up the codes. I am not a mechanic but, I have changed out my oil and filter, my spark plugs and coils, my heater control valve, my mass air flow sensor, my thermostat, the electronic coolant temperature sensor, two bypass hoses, fixed a head gasket leak( temporarily) , stopped coolant leak and no longer have oil in my coolant all just from watching you tube videos. My car went into fail safe mode from all the changes and it must relearn the fuel idle trims but first, I’ve got to fix the fuel injector code p0201 or p0117. Which, a mechanic would probably tell you that you need new fuel pump, and then a new ecm $2,000 later still hasn’t fixed the problem. You can clean your fuel injectors and that might do it. At 185, 000 miles things need replacing. Especially, if it has never been replaced. Mostly all of these parts I’ve mentioned can be cleaned with carb cleaner and they may function just fine without replacement. Go watch chrisfix on youtube and find out how to do it yourself .
