RB25det suddenly running bad

[GotsWapan]

Hi guys, 
Ive got an issue with my R33. Put 98 fuel in it yesterday from united (same place as always) then it started running shit. 
Went to drive to work this morning and got a couple of hundred metres down the road and it stalled. Left it there and came back after work and changed the spark plugs, got it started but still runs bad and the idle is horrible. Its got no low end power but after 3000 or so its not so bad. I can't see any hoses that have popped off or split cooler pipes or anything.
Whats the chance of getting a bad batch of fuel?

Most of the plugs were quite black when I pulled them out and one was a tan-ish colour.

Drained some fuel from the lines. Couple of small water bubbles in the bottom but I'll need to dry a bottle out properly and try again tomorrow.

Drain all the fuel. Replace from another source. That will tell you for sure if its a fuel problem.

Sounds familiar to my issue, see my thread. 

Can you check fuel pressure ? Pump maybe failing? Mine went all sudden to running poorly and after some testing, swapping afm and fuel pump etc, I’ve found it’s down compression on one cylinder

Wouldn't be surprised if the Wolfie lost a tune lol.

Where's Trent from Chequered Tuning to go on a rant about them lololol

The wolfs fine. Turned out to be water temperature sensor. Now my alternator has buggered up
