We've all occasionally stalled the engine, right?
I did today, after a 1 hour drive, ending in stop-start urban traffic, I think I misjudged the revs pulling out from a parking space, onto the road, on a slight uphill. The car went cloink and I quickly restarted it before the people in my village noticed the shame I bought upon them.
But the engine refused to rev over 1000. There was no power. And then there was a little bit, allowing me to move the car, and then again it slipped to 1000rpm regardless of throttle position. I barely nursed the car into a car park, using 100% of the single horsepower the engine was giving me, and 150% of my ability to improv apologies in universal mime. (I completely blocked the car park exit for a bit).
I didn't have my code reader with me today, but the dash did not indicate there was a code.
Left the car for 2 hours, started it up, and there were no problems at all. Drove it 80 km home, half expecting it to slump again, but it never did.
This is similar to the symptoms I had that made me replace the fuel filter, but perhaps that was a misdiagnosis. I stalled the car that time as well. The filter is still fairly new.
Does anyone have a plausible explanation for the faux limp mode the car adopted? Did the EGR valve get stuck open? Does the fuel system do something funny on engine stall? Is there some ECU sensor input buffer that overflows with crap data after improper shutdown? Has anyone else had this happen? Is one of my sensors on the way out?
I searched for a few relevant descriptors on old threads, but didn't find anything.
