codes 12 (MAF) and 53 (r.02) disappeared and the car seems to be idling a better but still rough. i took it to the highway to giver her a run and it has no power. it took me like 5+ seconds to go from 40-50mph. and the car sputters throughout. Sounds like you're still running excessively rich. Could
be a lot of reasons. First quick check is to make sure the
little skinny vac hoses on the fuel pressure reg and damper
are on well. but funny thing is that i got code 55 this time. so i tried running the heated 02 test. rev her to 2000, and turn the knob on the ecu and it blinks once every second or so. turned it again to test the right and it blinks rapidly 3 times and it then the light just stays on without blinking. hmm. that means that the right 02 is failing right? but why don't i get a code 53 for right 02?
Code 55 just means the ECU can't detect that something's
wrong with the info it has. The ECU isn't infallable. Some
sensor could go bad in a way that the ECU might still think
was perfectly normal. can the 02 sensor cause this much of a loss of power and sputter? the z is still misfiring and i need all the help i can get. thanks again guys...
It really shouldn't cripple the car. It should make it run
crappy at low RPMs, it should lower your gas mileage some, but it shouldn't make the engine totally devoid of power. I'd go ahead and replace it, just to be sure that it's
not the problem. It's relatively cheap and it's easy
enough to do on an NA. But I think there may still be other problems lurking here.
