2000 toyota 4runner sr5 4wd $2500 No accidents, clean carfax. I have owned since 2012. Overall good condition for a 20 year old vehicle. Recently replaced starter, fuel injector, battery, plenum gaskets, spark plugs and ignition wires. Upgraded the brakes to the larger Tundra rotors and...

I replaced it. 99% sure it was on correctly.

Thanks guys! I didn't take off the plenum since it was #1. Just had to take the intake and throttle body off. I only replaced the #1 injector, but all 3 o-rings for that side. I am away on business now, but I will check for a leak after I get back.

The stalling and idle issues have gone away, but I now have a p0171 (System Too Lean (Bank 1)). Any ideas what this would likely be after a fuel injector replacement? Am I right in thinking this could be a fuel injector problem (too little flow) OR a high air issue (broken hose, MAF issue, etc.)?

Swapped out the #1 and it is running smoothly now for the most part! Thank you Jesus! However, it runs rough (drops RPM) at idle , especially when cold. Stalled a few times at idle as well.

Yeah, already swapped coils and replaced wires and plugs so it better be the injector! :violin:

Ok thanks. Well I guess I will swap out the #1 still. Now I am worried this still won't solve my p0301. Ugh.

So I am in the middle of replacing my #1 fuel injector. I had checked it when it was on the 4R with a multimeter and it was not registering a number, and the other 2 on that side were at 16. Now that I have all 3 off the car I decided to check them again and they are all reading 16? Did I...

But the code is throwing p301, p304. Aren't those different codes?

When I bought the 4r 3 years ago it had a hole in the muffler, so it ran loud then. Had the muffler swapped out a few months after so it sounded much quieter, but maybe it was still louder than normal and I just didn't notice. If I had to guess I would say that it might be a little louder now...

yeah, looks like it is. I edited the image, should work now. I think this one is the rear one?

Hey all, was just walking back to my 4R in a parking lot and noticed something hanging under the chassis. Looked close and I think it is an o2 sensor. I can't tell where it is supposed to go in. Look like the part of it is supposed to have screws attach it to something?

If I am still getting the 301 and 304 is that consistent with a fuel injector too?

Sorry, I think it was the whole coil. The whole piece that bolts into #1.

I swapped the 1 and 3 boot, and then cleared the codes. Took it for a short drive and threw a P0301 P.
