[Vel98]

So vehicle is a 2008 ve manual ssv ute stock. I have run into a problem where I am displaying p0174 bank 2 system too lean and p0302 cylinder 2 missfire and have a sulphur smell. I was driving around watching a live data stream and noticed when it started running rough and the engine light was coming on I was also displaying an ol-fault on fuelsys1 and 2 I'm stuck as to what the problem is all faults are also intamitent . Any ideas or help would he greatly appreciated ?

Misfire has probably melted the cat

I'm unable to find any cause for the misfire at this time coilpack leads plugs etc have all been changed with cylinder one to see if the symptoms follow has been compression tested and had the valve train inspected for faults. Injectors still need to be pulled and tested

 

[RiCeY]

Simple test is measure resistance through each injector at the connector terminals.

They should be all around the same, if one is a fair bit out it's cooked. Should all be around 14 ohms from memory.

Disconnected injector plugs and tested resistance of each injector other then injector 5 because that's a bitch without pulling more apart.
Results
1.16ohm
2. 60ohm
3. 14ohm
4. 21ohm
5. Bitch
6. 16ohm
7. 20ohm
8. 15ohm

Yep there's your misfire cause on cyl 2

Yea picked up a good injector from a mate to chuck I'm before I buy a new set

 

[RiCeY]

Prob also cause of Bank 2 running lean. New injector should fix both codes.

Hopefully if it does I will replace the lot with new

Runs even worse now than before constant missfire now as soon as it has any load and long term fuel trim goes 20 plus %
