you talking about this one?:

[richee3]

The Avalon uses the same MAF so you should be good there. As sensitive as it is, I would try to stay with a Toyota MAF, but you've already driven the car so that shouldn't be your problem. What do you mean, "built the intake?" I assume you mean you put the pipe and air filter in since that was the first post with the pipe pictured. But you might have actually built one yourself so I'm just checking there. Does the car idle well? Rev in neutral?

[Dangercart1]

yes lol, by built i mean i simply put one tube into another and capped it with a filter, as for idling, sometimes it idles very well, but other time it stalls or shakes violently at idle

yes, that one, and the big one inside the tube

I forgot the name to that blue vacuum sensor. It goes to the charcoal canister I believe. Its not much of an importance at all and will not mess up the ecu if you don't have the on your engine. Guys from the beams forums and on 6gc said that thing isn't very important.

I have it hooked up, but it wasn't set up to the charcoal canister so i did that last night, I also cleaned the air intake and the MAF sensor, the car is still driving weird, it works fine but if the RPMs get to high it bucks like crazy, I don't have a tach right now so I'm not sure what the RPMs are but it happens around 60 in fifth gear, 50 in fourth, 30 in third, and 15 in second, i'm not sure about 1st

60 is around 3K, same as the 5S. I assumed that's what you meant by "built the intake" but I wanted to double check. The blue thing that Bonzai posted is the VSV. As he said, it goes to the charcoal canister and isn't important to us at all. Apparently it makes a difference with a handful of MR2 guys, but not all of them and definitely not us. Does it matter if you're at full throttle or not, or does it just start running weird at a certain RPM, no matter what? Try unplugging the VVT solenoid and going for a drive. The BEAMS guys always like to start with that. It really sounds to me like a MAF issue. Is your check engine light on?

I can't hit full throttle, at 60 (in fifth gear) the engine just bucks vigorously my thoughts are focused on the 4 engine codes, i also need to reset the ecu again soon to see if i got rid of them but two of them are involving the intake 1 involves the O2 sensor, but again i have no exhaust (hopefully getting that done tomorrow), and the fourth is fuel pump related (i have yet to get a stronger fuel pump) so i'm thinking its the ecu that's throwing off the engine of the lack of fuel, there are a few things i'm going to try, like which way is the MAF supposed to be facing? open end facing toward or away from the filter? Any suggestions are definitely appreciated, thank you all

test your fuel pressure directly at the pump with a 12 v battery.

No need to upgrade your fuel pump, the one used on all Naturally Aspirated Celica's from 7afe, 5sfe, 3rd gen 3sge and 3sfe are all the same fuel pump. Just make sure then when you test your fuel pressure, it read 38-44 psi.

Open end of the MAF goes towards the air filter. That could be your issue. Definitely reset the ECU when you change/fix anything.

I wish that was my problem, but i've got it facing the right way

[Dangercart1]

so went to get the exhaust done and they said they couldn't fabricate a down pipe, so now I'm on the hunt, would the down pipe from the 1.8 work? I included a link to one of those ebay ones it looks the same, i inquired about measurements but got no response.

It looks similar but I doubt it. The BEAMS uses 2.25" exhaust, and that is only a 2" outlet. It's possible though. There is a BEAMS b pipe on EBay right now- $195 shipped, has the O2 sensor.

ordered the pipe today

The exhaust is finally on and sounds good, unfortunately it's still not running right, and the only thing i can think is the damn maf, is it possible i got a bad sensor? maybe it's the wrong one, i know toyota makes a few different ones with the same size plug. does anybody know the part number?

[richee3]

The MAF is 22204-20010. It's from late 90's Avalons and Camrys with the 1MZ.

yep, that's the one i got, I'm going to try and get another, I'm thinking the one i got was bad.

A few questions.

What intake are you using?

Did you reset your ECU to clear the O2 sensor code, and did it clear the code?

You can't hit WOT in any gear, or just 5th? And what do youeans it starts bucking?

It's basically running, correct?

I'm just trying to get a good idea of what your motor is doing.

[Dangercart1]

The top of the intake is the stock rubber elbow, which than goes to a metal tube made for the 97 avalon so i can fit the sensor in it, and the filter came with the tube. Yes i reset the ECU and yes it cleared the o2 sensor. I'm not sure what rpm it is, but no matter what gear I'm in once i hit it the whole car shakes violently. It's like the engine is trying to jump out of the car, and stops accelerating all together. Thanks for the help so far I do appreciate it!

[richee3]

The Avalon and Camry use the same 1MZ engine so the intake should work, theoretically. Can you get a measurement of the inner diameter? There's a slim chance but maybe the Avalon and Camry use different pipes. I'm glad resetting the ECU cleared your O2 sensor code, but I'm assuming the other codes stayed? I'm leaning towards a bad sensor as well, though I would think a bad MAF would be bad across the board. Does the motor rev freely in neutral or does it still jump? It sounds like it might be a mechanical issue if it's jumping that bad. I'm sure you know my BEAMS is acting up as well, and our issues sound similar, apart from the fact that yours sounds much more severe. The help really isn't a problem. Other BEAMS owners have been gracious enough to help me out and it's the least I can do to help you out too.

Sorry for the lack of updates, school and work have been rough this week, also i managed to develop an oil leak out of the valve cover gasket, so i'm stuck doing that this weekend, I'll get that measurement as soon as it stops raining.
