Yeah, could be. Could also be a leaky EGR. The code 11 is troubling though. He should clear that and start from scratch.

Code 42 is the speed sensor signal. The speed sesnor is located behind the speedometer. It's used by the ecu for a lot of minor things. Also used by the cruise control. It should not give you the grief you're seeing however. Code 52 is a knock sensor signal fault. This one is bad news as far as...

Johnathan, your car is clean alright. Those numbers show an engine in tight closed loop control. Either that or you have great catalytic efficiency. It's likely you have both. I'm assuming the limits you posted were taken from your last test report. Did you know in Cali those limits are based...

nope

No wonder the car goes good. I bet the fuel economy sucks though. The MIL is what boso said. It's what lay people refer to as the check engine light. He's also right about the engine running rich, just look at the CO. It would've been helpful to know the O2 and CO2 levels but it's clear the...

Oh, too bad so sad. I'm "knowlagable" enough to know the answer but one of the facts I have is that people who ask for help with an attitude make them not worth giving it to.

You be welcome. Another satisfied customer ;)

Yeah, "help, car broke" posts are frustrating because of the need to play 20 questions. The guy doesn't give emissions number or diagnostic codes so I guess we're supposed to deduce them for ourselves. Those "guaranteed to pass smog" additives almost always contain polyamines. Polyamines are...

Joel, keeping in mind TCCS firmware varies among Toyota models, model years, and countries the following diagnostic codes (according to Toyota) will not illuminate the MIL under normal conditions ie; T and E1 in the diag block is not jumpered: 1) The "normal" code (duh ;)) 2) 11 ECU power 3)...

Why would adjust the throttle cable to set idle? Not a good thing to do. Code 11 is a serious problem. Check the ECU ground wiring on the intake manifold. Always reference the proper ground when doing voltage testing on any circuit. Never just clip to a body ground. This is a common mistake...

Again, unless you post the emissions numbers there is very little anyone can do to tell you what the problem might be. And no, a new engine doesn't mean it should pass. In my experience it's the contrary. And if the MIL is coming on we need to know what codes are being set. You're asking for...

A bad AFM won't hurt the engine so the only "serious" problem you'll have is it'll run poorly. What happens when certain sensors fault is the ECU goes into fail safe mode. After all, what good would the car be if it stranded you every time a sensor went weird? In the case of a bad air flow...

What are the numbers? What mods on the car? I also need help from someone like Grim as I don't know what kind of test you guys use up there.

Jdub, I'm fond of the Spectroline stuff sold by Tracer Products:: http://tinyurl.com/lnppz That said, just go to the local auto store and buy some UV dye. InterDynamics sells most of the consumer versions and has oil, coolant, and A/C types. Get a cheap LED UV light from any A/C supply or...

;)

They use gaskets in other places but yeah, the crankcase halves are machined surfaces. They use a silk thread to seal them. They often still leak though as every power pulse tries to shove the cases apart. And Heaven help your wallet if the through bolts lose preload and the cases start...

I bet you're right Grim. As I mentioned in another post you can cheat on lots of stuff but the airflow thing will get ya every time ;)

UV trace, the only way to go. Baby powder sometimes works too. Trust me on these techniques, I own a Lycoming ;)

Since the air temp sensor is a completey independent part of the AFM the code 24 could imply a wiring problem or a lack of +5 volt power to the AFM. Ohm the AFM but be sure to check the 5 volt supply pin on the connector. I find it hard to believe the air temp sensor and the Karman would die at...

Not sure as I'm not totally clear on your description of the leak but might as well check the easy and common stuff first. Jdub seems to have a better handle on the area you described so follow his lead too. The CPS O ring is easy to do though. If it turns out to be that there's no need to set...
