borrow/buy/make a smoke tester. I like to remove the MAF sensor just to avoid blowing smoke at it but that's probably not necessary. There should be some different adapters so you have some choices as to an entry point for your smoke. One is an inflatable bulb that you stick into your...

After trimming 0.030" off the fuel rail spacers the injectors sat much tighter. There was absolutely 0 space for up-and-down motion and very minimal rotational motion. Still leaks by :dammit:. I'm charging the system with <1psi of air and it's blowing by the injector's lower grommet almost as...

My thoughts exactly. I'll pull an injector, hit up a hardware store or 2 and if i can't find some that could work then i'll throw the spacers in the lathe. Now that I think about it i just need to find a thin enough shim with a reasonable OD then I can stick em in the mill for the ID. TBH...

Small update on this. Motorwest has been very nice to work with and have seen this issue with 1 other customer who was also supercharged. They said that changing back to the older style brown injectors fixed the issue and offered to replace my current set. I'm wondering if I should go that...

Interesting take! I thought those grommets were just dust caps or something. How are those holes supposed to work if there's a grommet covering them? I actually don't remember seeing holes there, gonna try to find some pics in my phone's albums...

I fixed the exhaust leaks, replaced afr/o2 sensors, cleaned MAF, and replaced the air filter with no improvement. Also double-checked my spark plug gaps and cleaned any corrosion on the plug wire to coil pack connections (those caused a stumble for me in the past) The rear cat is def dead tho...

2 new oem sensors are on order from Toyota. Even if the a/f sensor seems to be in working order I'm just gonna rule that out for sure. As far as I know they are original cats. I've got like 14 years of service history for this car and no records of them being replaced. According to my temp...

I have no CEL currently but once in a while a P0420 does come on. Mainly looking into my high LTFT (~14%) at idle and low throttle and more recently a stumble that happens at low-load acceleration. All of my fuel system components are pretty new, MAF is new denso, spark plugs are new denso...

Nice thx vry much for the explanation Very helpful thank you

Edited original post to add this info: I took catalytic converter temps again after a good drive and it looks like the first cat is lighting off and the rear cat is not. First cat's outlet is >10% hotter than the inlet. The rear cat's outlet is slightly cooler than the inlet. Still trying...

sorry to revive this very old thread but I've got a question that I'm having a hard time finding an answer for. I have a cali emissions 1999 with the front a/f sensor. my o2 bank1 sensor1 voltage is always sitting at .6 or .7 volts this sounds like my sensor is not working/is faulty. It is...

thx robb, i tried this and saw exactly the behavior you described

1999 5vzfe TRD supercharger URD 7th California emission I feel like I'm always chasing something with this car. Using torque pro my o2 sensor1 (a/f sensor) voltage pretty much only stays at 0.6v. From what I've mostly read this means the sensor isn't working as it should be oscillating...

1999 5vz cali emissions trd supercharged with urd 7th Torque pro says my car is always in closed loop. Even on startup in the morning. The only time i see open loop is when theres a heavy engine load (such as during hard acceleration, up steep hill, or deceleration). What could be causing...
