Gen 2 3sgte near marietta or east cobb?

Spektrewing386 · 12-21-2006, 12:53 PM

Is there anyone with a gen 2 3sgte around here that is willing to let me borrow their o2 sensor and AFM in order to determine if mine is bad?

the2ndr · 12-22-2006, 01:10 PM

What is the car doing?

You might try contacting Brian (ncturnal).

i noticed there is a white mr2 in a subdivison on Post Oak Tritt near the corner of Sandy Plains...wonder who that is. anyway, its running super rich accorind to the many failed emissions reports i have. it hesitates/bucks in low gear sometimes. i'll just copy/paste my thread from the other board:

For the past 4 months ive had a bad hesitation problem. Sometimes in 1st gear, it bucks bad and then after a bit of hesitation (around 6 seconds) it fixes itself. What I noticed is that when in hesitation mode the manifold pressure is higher than what it is normally and i can sort of hear a popping noise. I also hear the turbo push air even when not in boost. When its hesitating the vacuum could be 10mmHg or if i push the gas hard enough, i can get boost when hesitating. And after about 6 seconds it pulls through and I see the manifold pressure drop (I try to keep the throttle in the same position for diagnostic purposes when this happens).

Even when it is not bucking, the car generally seems a lot slower than it used to be. This problem is making me fail emissions (3 times so far). The reports from the emissions are:

Reading / Allowed
HC 283 / 132
CO% 8.83 / 0.73
NOx 39 / 945
CO+CO2 18.3 / 6.0min

What do these numbers tell me?

Things that have been replaced:

intake manifold gasket
T-VIS gasket
IAC valve gasket
throttlebody gasket
valvecover gasket
numerous vacuum lines
got a crack in EGR pipe when taking out intake manifold - got EGR blockoff plates
Seafoamed it about 2 times
distributer cap, rotor - all Toyota OEM
sparkplugs about 1,000 miles old - the recommended ones
corrected timing from 30 degrees advanced to 10 degrees

just put in new Toyota OEM sparkplug wires. the emissions test was without the new ones.
I ordered a fuel filter last night. well see how that goes.

how did you know the motor was advanced 30 degrees? The measurement on the cover doesn't go that high. Did it actually run @ that timing?

Damn I have a spare afm, but its in Savannah and I'm in Atlanta till xmas.

It might run, but it definately wont start at 30btdc.

it was so to the left that you almost couldnt see it from looking straight down.

Ncturnal · 12-23-2006, 01:17 PM

I have an AFM at the house. How many miles are on the O2 sensor? Do the car have a cat?

Spektrewing386 · 12-23-2006, 01:36 PM

the o2 sensor probably has 2000-3000 miles on it, and a new cat was put in at the same time as the new 02 sensor

Ncturnal · 12-23-2006, 02:27 PM

OEM or aftermarket O2?

Spektrewing386 · 12-23-2006, 02:37 PM

i assume OEM, i wasnt the one who put it in though.

the2ndr · 12-27-2006, 01:01 PM

probably a boost/vacuum leak. No cel means you probably have a leak somewhere. Check all the hoses from the turbo to the throttle body. Usually more than half the time its because of a leak somewhere causes the bucking.

Spektrewing386 · 12-30-2006, 11:08 AM

So Ncturnal, whens the next time you are going to be at FinishLine?

Ncturnal · 12-30-2006, 12:00 PM

There almost everyday. I just left for lunch and will be back in an hour.

Spektrewing386 · 12-30-2006, 12:36 PM

im going to pick up my car from the shop tuesday. you said you had an AFM i could test with?

Ncturnal · 12-30-2006, 12:48 PM

Ya, it's at my house. I'll have to bring it over.

the2ndr · 01-02-2007, 03:08 PM

hey, hit me up if you haven't found the problem yet. I have the AFM.
