Problem has been solved, ended up being a combo of timing not properly adjusted, and a partially blocked fuel filter.

Fuel filter was replaced when i brought it as the one in it looked VERY old still toyota genuine probably replaced once..
replaced with Ryco- than full fuel cleaner run through, 10xxxkms later used a toyota injector cleaner.

so id say it put alot of crap from the tank in to the filter? as i just replaced it friday with a genuine one then had timing checked and found exhaust half a tooth out and it reading 8 degrees
timing fixed and adjusted to 12 degrees.
runs like a dream now.

I think I've been luck with my motor too as my plugs look exactly the same!

Doug, the motor had about 230k kms on it when those plugs were taken out, and they'd been in for about 40k kms.
But it's now up to about 265k kms and still running the same - great.
When I bought the car I must have been lucky and got a good one. " />

That is the correct heat range plug. Bloody hell Ian . Those plugs are sooooo perfect!!! How many kms on that engine now? Gatesys. Your plugs really don't look too bad to me. Cheers.

Gatesy, FWIW I just had a look the pic of your spark plugs, and they do look quite a bit blacker than the ones from my own 3SGE motor when I changed them. (see pic)
They are NGK platinums, and the cars performance was great as well as fuel consumption.
Fairly high K motor too.

tested coolant temp sensor, tested within spec.
going to check base timing.
very sure it may be off as it is gutless taking off.

Mrskylighter
The bgb will tell you how to test it. It would of been one of the first items id check or replace for your issue. A new one is cheap.

I have had these issues before with my previous gen2 engines.
Try as 'Mrskylighter' has suggested, & test & change out the 'Water temp sensor'.

Section (FI - 168) in the 'BGB'

Now you mention it
When I take the oil cap off it does smell a bit like fuel in there,
Is there anyother signs to show a possible oring failure

They look fairly black besides the electrode section
Do my spark plugs show it's running ok?

Don't really want to pull it apart to replace injector rings
But the head is coming off next month for a full reco and some bigger cams and valve springs etc so may wait till then

You were saying your cars running rich and your exhaust is all black etc... but not a single one of your spark plugs are black. It doesn't actually add up to running rich. If you were running rich based on a faulty sensor your spark plugs will definately be black. Did you check the oil, do you have raw fuel in your oil? If so then it can be your injector o rings if you have side feed injectors. Based on your plug color though, your car doesn't look to be running rich.

It simply changes its resistance based on the coolant temperature. If its reading out of whack the ecu will think the coolant temp is different that it actually is. Adding more or less fuel then it should.
It would prob cause a fault code if unplugged or completely faulty (break in wiring)

Bgb is easy to find. Just google Mr2 bgb and the first few web pages will have it.

Really?
I was told it would throw a code if it's bad, which it has no codes stored.

Anyone got a link to the bgb?

No haven't tested that yet
Do you know of a way to test it?
Where is it located in on the block?

You checked the ecu coolant temp sensor? Green plug one.
