Fuel injectors

Ok just cleaned the maf sensor and put it back together now it's missing worst than before, drove it around the block and heard what I thought was a leaking exhaust ( kinda like a back fire) under the passenger side of the yota, so I got back to the house and crawled under the yota and noticed catalytic converter was glowing red!!!

How did you clean the MAF?

Your car is misfiring like crazy. The fuel is dumping into the exhaust and igniting causing a back fire. Your injectors are most likely NOT at fault.

Replaced wires and plugs. Go with OEM plugs and wires. Just got all 6 plugs and wires for $70 OEM online. Will most likely fix your issues.
 
Just cleaned the maf sensor with electrical cleaner. I changed the plugs about two years ago do I guess I'll change the wires, aren't they just 3 plug wires on the drivers side that goes from the plugs then go over to the passengers side to the coil packs

Yes only three plug wires.

When you did the plugs what plugs did you use. Cheap plugs will not last very long at all. You can get maybe 10-50k miles on cheap plugs where NGK and Denso will get you a good 100k+ miles.
 
The plugs I'm pretty sure where ngk but I haven't changed the wires in for ever, does Oreillys carry the ngk plugs?

You are having misfire issues. Start from the beginning. Pull plugs and inspect. If any look bad replace them all. They must be dual electrode plugs.

If still misfiring replace wires with OEM or ngk blues.

Then move to coils. Research how to test the coils if still misfiring.
 
Ok I ordered the blue NGK wires and the local Toyota dealership has the original densi plugs do I'm headed there now to get them, probable want be able to switch them out until this Saturday but I let you know how it went. Thanks for everyone's help.
 
Well I went ahead and put the plugs in tonight lol just to see if that would help the yota but it didn't, I guess we will see if the wires will do it when I get them tomorrow. The plugs was NGK, the plugs on the passenger side looked fine but the ones on the drivers side was real black.
 
Well the wires fixed the missing thank the lord, reset the codes and was good for about a day then code p0171 came back on. I've changes the upstream 02 sensor about a year ago so I might go ahead and change the down stream

yeah, no kidding? I can remember when the quality of Pemex was suspect, but now I think it's actually better than US gas. The whole ethanol from corn thing is a sham, it's too bad MX is going to do the same thing. I know big parts of Brazil the cars run on straight ethanol from sugar can/beets/whatever.

Hard to beat good old gasoline for BTU's and usability.
