Don't ya just love this place.
Ask and someone can usually help out.
Sorry I had not played with your engine so didn't realise you had side feed type.
this is what threw me, and also for how I explained cleaning injector by hand method.


Hope you can simply fix buy replace filter and its not in the loom.
you are going to move 1 and 6 around still?.
might be the go still.
incase its the injector after all.
The ebay link is good info to have for tracking down bits and prices are excellent.
If your prices are similar its worth getting a set of filters and all seals incase.

anyway hop it turns out well for you.
Cheers

Yeah thanks Robo.
Im going to order a full set of 6 filters $10 each and O rings for $35. I might even get them cleaned while there out, only $20 each. Although I run LPG as well so not a major drama there.
It'll take a few weeks to get here so in the mean time I'll swap 1 and 6 over and take it for a run to check what the go is.

PS The shake happens on both petrol and LPG when I push injector 6 so therefore I guess its an air leak at No 6. If running on LPG the injectors would't be working so that's how I came to the conclusion it must be an air leak. Either that or a crack in the injector / fuel rail but I can't see anything obvious.

Just a process of elimination and not to get frustrated.....

May I suggest you add Morreys upper cyl lube to you petrol tank.
to help maintain a clean fuel system.
you really want those injectors to work properly when you switch over or run out of LP.

Just fitted the upper cylinder kit with that stuff. Previous owner didn't have it and I was surprised how smooth it was on petrol. No surging or anything. He said he ran a tank of petrol every so often.

Let you know how I go with the dizzy....

Yeah good idea for gas.
You can also add a little direct to the petrol tank next time you fill up.
Morreys have cleaner product built in as well as lube qualities.
Problems accure with leaving fuel in injectors for extended periods.
Gumming up and deposits sticking etc.
The princable idea, Morreys should help minimise this trouble.

Penrite is a good lube but does not have cleaner built in, had no engine trouble with this, but returned to Morreys for cleaner additive.
Only used Penrite for a short period, can't really say 1 way or the other for sure.
I spoke with Penrite tech man, he gave me that information for no cleaning additives in their product.

Hate flaslube caused bad ping in a sound engine.
Fuel doctor returned worse fuel ecc, 3lt worse per 100k.

Update.... Until my new o rings and injector filters arrive from USA I replaced the bottom o rings and swapped over injector 1 and 6. The old o rings were worn and looked very sad. I didn't pull out any of the other injectors and decided to do this when the new parts arrive. Overall the vehicle idled smoother, and seems to start a lot easier. The potrol is a lot happier.
Bought a new o2 sensor which I'll try and replace over the weekend and check out the timing.
So far fingers crossed so good... Thanks for your input and help..

[Robo]

The o2 sensor.
might pay to use anti-seize on new 1.
as you have probably just found out.
old one was a pain to get out hey.

[4by]

He he..... Hard to get out is an understatement...... I'm still trying and already broke a spanner. Next ill try to get some heat into it with a flame and give it another go. Not to mention its on extractors and not a lot of leaverage room. Fingers crossed I don't rip my knuckles open......

[Robo]

you can get special tool for this.
but don't know if it would fit yours.

once you do get it.
work into the thread fair amount of antiseize, to ensure full coverage of thread.
I ve done this with exh stud nuts and twin sensors on my GTR as heat is a plenty.
and seized ie a real problem in these areas as we know.
It does work, but don't know how long it will last.
