ArmyofOne Posted December 4, 2005 Share Posted December 4, 2005 another question i have is how should my car run with the cel on and a its reading bad o2 sensor car running lean ← it will run normal, you will just notice a decrease in gas mileage, if anything at all. :D the O2 sensors are emissions related, not much else.

Toysrme Posted December 4, 2005 Share Posted December 4, 2005 '94 OEM Camry repair manual p0171 You're rear bank is running lean. o2 sensors read richer as they age, however when they age & read lean the heater portion may have began to fail, or it's go build-up on the o2 sensor, insulating it. Temperature can make a 33-50% chance in sensor output. If it's not up to temperature completely, it'll read leaner than normal. (If you haven't figured it out yet. Toyota EFI for engines with multiple banks have their fueling tuned for each bank. Fuel wise, it's two completely different engines. Spark wise it's the same engine.) Replacing the o2 sensor is the right call, because anything else giving you a lean burn will affect both banks to some extent. Quote Link to comment Share on other sites More sharing options...

Someone had said carb cleaner was good, and cheap. After that experience, I went back to Gun Scrubber. Quote Link to comment Share on other sites More sharing options...
Toysrme Posted December 9, 2005 Share Posted December 9, 2005 Reset the ECU. If it comes back, replace the 2 main o2 sensors. Bank 1 is the right hand bank (rear). Sensor 1 is the main o2 sensor, sensor 2 is the post cat o2 sensor. Quote Link to comment Share on other sites More sharing options...

Someone had said carb cleaner was good, and cheap. After that experience, I went back to Gun Scrubber. ← Yup it works! I only use it on my S&W 500 on the cylinder along with my 44, The rest is the normal cleaner. You have to be careful with it since it cleans all the lubes off too.

I would start running a gas add in your car. I used Amsoil PI for a long time. Now switch to FP60....FP60 is cheaper and does more. Quote Link to comment Share on other sites More sharing options...
Toysrme Posted December 22, 2005 Share Posted December 22, 2005 I'm with him. Dealer/mechanic injector cleaning services are a huge rip-off. 90% of the time they do it, that's not the problem anyway. Quote Link to comment Share on other sites More sharing options...
