05 altima randomly dying
Hello, first post & wifes car has an issue, now
I have an issue.
05 Altima 2.5, 175k, norally a great car.
Random dying any where from 10 minutes to
several days of running. Try to restart and
seems like the battery is dead
but let it sit a while(and that time will also
vary) it will start & drive normal.
Replaced, upstream O2 sensor, cam & crank
sensors, plugs & coils. Reprogrammed
throttle after sensors.
Cleaned MAF with proper cleaner. Fuel pump
was also replaced about 2 months before this
all started to happen.
I would say vacuum leak maybe for dying but
not the no start due the battery acting dead.
Only code was & is P0420, clogged cat?
Thermal temp is 410F which is low end of
normal op temp.
Would a bad downstream be causing this
issue?
Thanks Paul
