OK. Here we go. I’ve been driving it a few days. Interestingly, the fuel mileage has increased from 20mpg to 25mpg. Here’s the current codes:
P0420
P0420 (listed again for some reason)
P0441
P0446
So, this is different than when I started.
ECT 169
STFT B1(%) @ 2900rpm bounces all over the place between +2.3 & -3.9, at idle (1900rpm) it’s pretty steady at -11.
LTFT B1(%) @ 2900rpm pretty steady at -3.1, at idle (1900rpm) it stays at 0.
MAP (inHG) 10
Spark adv 16.5
TPS (%) 10.2
O2S B1 S1 (V) bounces all over from 0.090 to 0.565
STFT B1 S1 (%) 19.5
O2S B1 S2 (V) pretty solid around 0.895
STFT B1 S2 (%) 99.2OK, I’m the new guy resurrecting the old topic.
I’ve been working on a 99 Corolla. I pulled the engine, replaced the rings, etc. The engine runs strong & doesn’t smoke. But it has the P0171 and is idling too high. I’ve replaced the PCV valve & most of the vacuum lines. I’ve tested for leaks with the carb cleaner trick. Nothing seems to indicate a vacuum leak. When I got the car it already had the catalytic converter removed and replaced with a piece of pipe. It also needs a muffler. The old one has some serious ventilation in it.
I have a decent Innova scan tool. It will give me live data. Part of the problem is I don’t know what the data means. I don’t have any way to know what the values should be.
Thank you for your input!
