the only trouble similar to what your explaining with the ZE is when i got a little water in the lead plugs in the head..what the hell were you doing near the injector plugs if you were tightening the sc belt?

Sounds like either timing or you have siezed the pulley bearing.

Guys wouldn't the water in leads give u trouble over the whole rev range.
ALso the pulley would make an awful noise if seized? A timing change would give you lost power over the whole rev range and only work well in one area?

Not if you cant set the timing advance because there is a vac leak so the idle hunts when you try. I had this for a few weeks because i had a huge leak and so the ecu kept idling up.
The timing advance changes as soon as you hit boost, so thats where your problem lies,

The car idles perfect no hunting. So if the boost changes timing then i might be going out on the Knock sensor when i hit boost?

Can you explain this better?
You don't earth injectors.
They are earth switched, unless the 4agze is different to every other motor out there?

There is an earth for the ECU there by the injectors
Brown wires all 4ages have it, these give you grief for the injector firing. Don't the injectors work off a pulse which breaks the continuity?

All Toyota's I have worked on, give 12V IGN to the injectors, and the other side of the injectors are connected to the ECU.
The ECU then grounds internally, thus firing the injector.
I'd say what you have earth was not the injectors, but the ECU itself.
Either way, it sounds like its not the problem

well no not really..i could drive my car fine..but when it came on boost it sputtered and jerked..and i know it was water cos i was experimenting with water spray on my FMIC..the pump kinda squirted water EVERYWHERE!..after running it for a bit..pulling the plugs off and blowing it out with a bit of compressed air she was perfect!..can be something as simple as that..

OK so its the earth for the ECU, this isn't the problem?
Any other ideas, i could swear that it is fuel related

if your concerned it's fuel related...what sort of fuel are you running? put some av gas in her..then see how she runs! (they love it!) maybe check your fuel reg and check the plug gaps.. check your leads also..it may not be water..but if there is a crak in one you'll know about it..

i had a simular prob with my 3sgte. does the car go ok or not so bad when it's colder?? mine use to cut out and stutter under load (1/2 throttle or more), more evident when the car is warmer. i had a suspision it was the leads. brought new ones and it is 100% now. check the resistance in ur leads.

OK i will check for spark problems.
I checked the diagnostics and it spat error code 21 Oxygen sensor signal; but it has an asterisk in the book(toyota) which says it airflow meter model only. Whats the go with that asterisk?

STill no luck, i will get new plugs today and install.
If you pay attention when accelerating slowly you can feel a slight miss, my old Mazda (carby) use to do this when the fuel filter was due for replacement. I haven't experienced this with a injected car yet, has anybody felt missing due to the fuel filter?
I checked the O2 sensor heater circuit and it has continuity and low resistance seems ok. It says that the signal HT is fed from the efi main relay, is this correct?Could it be a relay fault? ALso would a bad spark make the O2 fault?

unplug your O2 sensor and try it, replace your fuel filter (precaution) at least you can rule out things as you go..did you get new leads? if not pick up some silicon spray and cover them with as much of it as humanly possible..if this works it's your leads..the silicon spray will only work for a while but it will give you a chance to check..a new set of leads would be ideal..but if you can't find them...

it sounds like it could be that the plug gaps are too big to me. . .
the fact that it does it most prominant when on boost at around 4000 ( peak torque period ), the spark could be getting blown out.. . .
either plug gaps or ignition system is weak would be my thoughts.
good luck.

Yesterday afternoon in the blisteing heat the car ran well without a hickup for some reason and this morning was back to normal. I am starting to think that it may be a spark problem.
I should of got the new plugs yeaterday instead of thinking it fixed itself.Thanks for the silicon spray tip i will try if no luck with plugs.

This probably wont help
but i had the EXACT same problem with my 1jz
When I first got it, give it any sort of harsh throttle and it would lose all power for a sec in high revs and then get it back and hick up like that
I think it may have been an injector problem.. I just kept doing it.. and it went away
So I know thats not helpful.. but i wanted to share

I put in new plugs last night car is a little smoother off boost, but still not right. I checked the lead with a multimeter and all are under 10Mohms, i also wiggled them around when checking to see if they were broken. There is no sign of tracking from a rouge spark either. I checked the coils and the resistance between the + and - is about 3.8 ohms, i couldn't get anything on the secondary winding but that was the same on all four, normally you should get something in the kohm range on the secondary, right? ARe the coils different to normal?
How can i check the igniter, after a run i check it and there is no heat in it. This is a good sign right? Normally when i have had failed ignitors they either work or don't at worst they cut out when hot? I would get a signal from the ecu saying it woudl be the IGT signal if it was faulty?
Could it be dodgy fuel, i will change the filter tonight and see what happens maybe tommorrow i will have the injectors cleaned? I checked the resistance of the injectors and it seems to be about 4 ohms is this right?

I spoke to a mechanic today and he said the leads might be stuffed at the insulators. Has any heard of this before?

Dude I had this problem with my Jap spec GZE. It needs 98 octane to run well. In an emergency I ad to put some Caltex Vortex (shit!) in and as soon I did I was getting your exact problem. As soon as I went from Vacuum to Boost it would jerk and splutter.
My fix: flush as much of the fuel out as possible. Fill her up with Synergy 8000 or BP ultimate. Drive around for an hour or so and she should run fine again (might take until the next day)
Good luck and try this before listening to any mechanics' waffle.

Yeah i checked the leads at the insulators and no prob there just for safe measure i taped the insulators up and sprayed everything with silicone spray, still the same shit.
I had to fil up today so stuck some optimax ( the usual) in and see what happens, i think i might get the injectors cleaned and put in a new fuel filter any way?Maybe even some octane booster for good measure?
I've given up on the spark situation for now, the other interesting thing is that it is throwing error code 21 from the diagnostics, oxygen sensor? Could that be from running lean or something?
This is begining to give me the shits.

that would have been my next suggestion..the bp down the road from me closed the morning i really needed fuel..had to use some straight av gas to get to the nearest shell 4 suburbs away..SHE WENT LIKE A ROCKET!!!

Looks like the clean injectors improved the problem dramatically, have got some octane booster for next fill. I think it was a combination of dirty fuel and blocked injectors

yes ... and without a proper cams permit, you can't buy it for non aero use.

he he non aero-use...my mate uses it in his drift pig, i'm sure some of you have seen it around..Option1Garage sponsored S13, blue, basicly D1 spec, it runs on av gas, he has 3-4 jerrycans of it at any givin time! (it uses alot of juice!)
