Let’s talk about ping. Again.

I just left it on. The kit is coming in tomorrow and I’m hoping it’s early so I can install it tomorrow as well. I should also be getting the O2 sensor flange so I can get the AFR and Boost gauge up.



Also, if someone could take a look at the linked diagram in this thread I made and tell me if I’m correct about the O2 sensor wire to the ECU labeled “O2 heater” is the pin I need to connect to.

Did you buy a combo AFR Boost/Vacuum Gauge all in one gauge? I'm thinking of getting one instead of two separate gauges

 

Check out PLX. One gauge can do everything. You just can’t view two different functions at once on the multi guage. Unless you get the smartphone dongle. Then you can do it all from your phone. Pretty cool. And, I don’t have to have a new bung installed. I ordered a threaded 02 flange that goes on the wideband and it will take the place of the factory 02.

I just need to be sure that pin labeled 02 heater sensor is the pin I connect to the AFR.

 

Have you ever checked your mass air flow sensor? When these go bad your engine will
knock and you don't get a code that the sensor is bad.

 

No I haven't, how is this checked?

 

Don't know but a lot of people here have had issues with these sensors, and pinging from a bad one.

 

FROM ANOTHER THREAD BELOW
I suspect that the factory MAF sensor will last at least 300,000 miles with routine cleanings. I have thought about buying a factory MAF to "keep in stock" but I really can't justify it. I have 168,000 miles on my 2.7. I would be more suspect of components such as IAC, EGR and maybe even temp sensors than the MAF when it comes to the engine not running right.
I would have thought that a long time ago, but they are very fragile for one and for two they can make it seem like you did something if you clean them. They usually cause emissions to go crazy and you wont get a cel 9/10 times, they cause ping/knock and control shift pattern, the Supra owners know this all to well; they have the same auto trans as us and those guys tune all the time. They tell me for optimum performance change out before 100k. FWIW... theyll go way longer as others atest to, but most of you guys dont live in the Smog Star cert state California and these will have you buying o2 sensors and afr sensors to pass smog, which are as expensive. Some of yall might not notice the power loss due to a supercharged truck with fuel mods it will mask that hidden power, trust me Im on my fourth at 265k running an afe dry filter. I just ain't the one on the side of the road ever waiting on a tow, thats worse. They tell the truck how much air is coming in, and air temp and fuel delivery, so if thats not important to you dont change youre oil either. Tha IAC or temp sensors on my truck ohm out perfect at my mileage and a new maf is what fixes my truck most times I get a loss in power or exhuast is rich. Just tring to help you understand. I forgot the mention of egr if you live in a non smog state, inspection only state, block that power robber! Most of us dont even have an egr and btw a IAC will cost around 250.00 bought a new one for nothing! Dang.

 

Not the tacoma tick. Probably not the forum to post on either. Just looking for opinions on what has gone bad here. worked fine this morning. 12 hours later the truck is angry. my apologies for the lack of light.

 

That is a way bad sound!def knock sound, I would be crapping my britches! You need to look at youre belts first in the light but I dont wanna tell you what that really sounds like unless you wanna really know..

 

It’s okay. I’m sitting down....

 

Apparently it’s a bad belt and idler pulleys.

 

That's good - it sounded like a rod broke!
