Po171, Po125, P117, P1135? Help! 2000rx300

[tgun08]

i had the codes pop up po117,po171,po125,and my range performance code i think p1135, then i had misfire codes random misfire. i changed my plugs to find i had platinum instead of iridium, then had to change a coil, i bought it in may of 07. with 130k on it. well after fixing the plugs and coil i still had the 4 codes come up. could one sensor trigger the other ones??

i have come to learn that the bank one is considered cylinder 1,3,5 and bank two is 2,4,6 side. the coil was in cylinder 5 that i had to replace.

code po171 fuel trim to lean bank 1????? fix it or try a diff. sensor

code po125 ect should i replace that one first.....??????

code po117 ect family......????

could the misfire cylinder cause gas to reach the o2 sensor bank 1 and damage it? leaving it with the fuel trim to lean code????

fixing the ect would that help with shifting if its saying the coolant temp is insufficient????

i have all the ????'s and nowhere to start. i could replace them all and be stuck with a hole in my wallet or get lucky and come out with just a rip....

Yeah, try cleaning the sensors and then reset the ECU to clear the codes and see if they come back. I don't think they will though. Or atleast the real issues may only come back. Then we can deal with that.

the only sensors i'm aware that i can clean is the maf

You can pull the 02 sensors from the catalyst and clean those with some parts cleaner. You'll se 2 of them. Those are the 2 sensors that are throing the cel up now. It's propbably read gas leakage into the exhaust and that is why your getting the cel.
