4AGE 100kw Smallport - running very rich.

Hey guys,
my car is running very rich after i replaced the timing belt, its blowing black smoking and i have a rather large power loss.
I'm chewing through petrol too! i've done about 100kms and used half a tank 
Any ideas why it would be running so rich? could the timing and stuff be out? causing this to happen?
Please help..

my guess is cam gears not aligned properly. might be a few tooth out.

Thats what i thought, timing.
But would it be retarded or advanced too much for it to run this rich? its blowing black smoke and apparently shoots flames 
I'm going to have a look at it tomorrow.
I can't really see the timing marks though, ill have to try and short out the ECU then see what its set at.
Ill let you know how i go.

if ur talking about dizzy, its probably retarded now since u say "shoots flames". Advance it (anti clockwise).
i suggest u look at cam gear marks and see if they are aligned as well.

Firstly line up the timing mark (a little cut on the inside lip) on the crank pulley with 0 deg on the plastic cover that sits behind the crank pulley. Do this by turning the crank clockwise with a 19mm (might be 17mm) socket.
There are timing marks/ridges on the plate behind the cam gears which line up with dot/holes on one of the teeth of each gear...
The inlet cam gear is ~10 oclock and the exhaust is at ~5 oclock.
For the dizzy you need to have piston #1 at TDC. To do this take the spark plug out, get a long pencil sit it in the hole and turn the crank clockwise until the pencil stops coming up... Then just a tad more before it starts dropping.
Now make sure the dizzy rotor button is 10deg past #1 spark lead... You may need to play a bit and if the dizzy is way off you may need to remove it to rotate the gear one tooth. Btw the dizzy turns clockwise too... (Pistons 1-3-2-4).
I hear a timing gun is easier, but I dont have the points to short on the Diagnostics terminal so....

this is referring to the dot where the came gear screw is i presume.
There should be marks on the edges of the cam gear that should align with indicators on the plate which should be AROUND 12oclock on both sides.
spend some time looking up the tech docs on main page. On the ignition section it shows how to align cam gears with diagrams. Easier that way. (i know coz i just farking changed my cams and its bloody tedious!!)

I was refering to the marks on the edges of the gears 
I hope you changed your cam seals, last time I changed cams I didnt... It ran great for a couple of days, then the oil started coming out! smoke and oil everywhere... still cleaning it out!

The cam seals are the rubber rings that sit on the end of the cams. Behind the cam gears.

Hey guys,
still no luck, i have checked the timing a few times, and its set right, 10 degrees BTDC, and 16 degrees BTDC with the ECU unshorted.
I don't understand why is running so rich, its only started doing it after i replaced the timing belt, and now i blows alot of black smoke and is chewing petrol. 20L / 100kms.. it isn't good..
Can someone please help!

sounds like a trip to a mechanic who can put on all the sensors and shit and adjust timing or whatever it needs

Its been to the mechanic a couple of times, my brother is a mechanic.
They don't understand why is running so rich, they said it could be one of the temp senders.. i don't beleive it would be because it only started happening after they did the timing belt for me. they said everything was done right, timing etc.. but i don't beleive them.
When the car is stone cold it doesn't idle at 2k RPM like it use to. it starts and idles at 1100 RPM.
Any ideas anyone?? otherwise ill take it to another mechanic.
Cheers

Hmmm thats one thing i haven't tried, ill see if i can find one from the wreckers, i don't have one lying around...
The O2 sensor is the sensor located at the bottom of the extractors / exhaust manafold?
Thanks for your ideas Hunty...
Anyone got a spare O2 sensor lying around that i could have?
Cheers

yep thats the one, any one that has the same flange and similar dimensions will be fine as long as it is a 1 wire type, like i said mine was from a wrecked SV21 camry, i think, i got it at a wreckers for $15
Good luck!

Ok, i have spoken to a few more people.. i haven't had a chance to replace the O2 sensor yet.. but that will be done satruday..
I have been told that the cams could be a tooth out. which lets it run, but not very well, would a tooth out cause black smoke and for me to use about 30L / 170kms?
I don't understand why its doing it. i keep getting told that the mechanic put it back together right, but i don't beleive them.
Please help!

If the cams are toothed correctly, check that all cables are connected if properly, assuming u have done so.

Gee - sounds drastic. Check vacuum hose to fuel pressure regulator (FPR on end of fuel rail. Usually sees vacuum, if disconnected will see atmospheric pressure all the time shooting more fuel through the injectors for a given duty cycle).
They might have forgotten to reconnect a few things. Have a look around. But yeah it could be the cam timing out. Didn't know 4ages could drink that much. If all else fails take it to another mechanic, can't be great for the engine or the wallet when you fill up.
