Check Engine Light, Air Flow Issue Options

[Havok1997GT]

Guys, i need help with this one, cuz im lost. My GT is giving me a Check Engine light, The read out says something like Inadequate Air Flow. Ive done a complete Wash of my Intake. I had my Tech that i go to for tools i dont have, and he said he check all the Sensors and said they all worked fine. Ive Reset the ECU 3 times now. After the Bath of the intake i got 160 miles before it went off again. Thinking it was a faulty read i reset again and got 124 miles before the light came back. Now the Next part is going to be a little hard to explain. On the Intake (After Market Intake) right after the Filter connects to the tube is a sensor. I think its either the Mass Air Flow or the Air Temp Sensor, or something. The grommet was so tore from age that it wasnt holding the sensor in place anymore and it was just kinda hanging from the Tube. I went to get a new grommet for the sensor and they didnt have any the size i needed so i got a few different sizes and rigged 2 together. Basically the issue was one was the right size for the hole in the Tube but to big to fit the Sensor and the other fit the sensor but not in the Tube. So i rigged it up so it will fit and stay sealed, way better then what it was anyways. The thing is though after that i did the final Reset of the ECU and i got 8 miles before the Light came back on. IM LOST!!!!!!!!!!! if you have any ideas help me out. Im still working on a few things but i need all the help i can get.

Thanks

Have you checked the clamps on the intake?

[Havok1997GT]

Yes Panda. I believe you where the one that didnt put them on right the first time!

Anyways. i left out some information that i didnt think was important at the time but now that i think about it, it might be the problem, so now i have a question instead of looking for help.

Before i started having this Air problem i was having a misfire problem, on all 4 cylinders. I was leaking oil into the Distributor which was causing the misfire. Me and Panda Replaced the plugs,wires,cap,roder and Distributor just to be sure. After that i started having this problem with the Air flow. Now when we finished with the Distributor we believed that we got the timing back on right, or atleast really close. Come to find out it was off and has been off since the swap. The thing is when we first had the misfire problem i wasnt pulling any codes, just that i was misfiring, it wasnt until after we did the swap that we started pulling this AZir code. up until now i thought it was just coincidence, but now im starting to wonder if thats the problem. Because if the Timeing is off the the Air mixture wouldnt be flowing right into the engine, thus it could be tripping the the sensors. So here is my question.

Could the Timeing being off cause me to get this kind of Code?

By the way, the Sensor i have been talking about is the Air Charge Sensor.

Update.

I have the code that is being triped. Its P0401. EGR System Fault. The ECM has detected too little flow on the EGR system. One would think that that is the answer to my problem. But my Tech said he checked the EGR and it was working fine. Causes that are listed are

1.Blocked Passage on EGR (Which i have already cleaned out the Intake so thats not the problem)
2.Failed EGR Value( Tech said the Valve was fine but this still could be it depending on how my Tech checked it out for me)
3. EGR Solenoid Faulty( Not sure what they are talking about)
4.Failed EGR Pressure sensor where applicable( not sure what they mean )
5.Failed EGR Postition sensor where applicable(not sure what they mean)

I am getting conflicting reports about this from friends that have been working with Toyotas longer then me. My boss is a Supra nut and said that the only thing that could pull that kind of code would be the Air Charge sensor, but the read out says its an EGR problem. HELPPPPPPPPP!!!!!!!!!!!!!!!!!. Im at the point to where im going to start replacing parts at random in the hopes that i stumble on it. And my instection is up in like a day and i dont know about anyone else but Houston cops love those. Im still working on it but any help i can get would be great
