- 2009 VE SS SILVER SEDAN
So we just bought a VE Omega Series 2 unreg to try and fix up for our daughter. Very much a mistake.
Drove fine, bought it......... got it home hestitated going up out drive way, drive fine otherwise. Owner said when it got hot it'd loose power and go into Limp Mode. Tech 2 showed multiple misfires. Coolant while running check showed head gasket was likely not the issue.
Replaced the water pump, injectors, spark plugs and coil packs (for sake of it being like new type thing). Went around in circles for a bit due to buying some cheap chinese injectors not realising (that story). Got some geniunes through in, fired up no misfire...... seemed fine. Backed it down the driveway put it under load with foot on brake no misfire...... few mins later started running rough and misfires on 2, 4 and 6.
Prior to the work it was generally just all over in terms of the misfire. We also replaced the crank sensor and updated all the various computers etc. It's got some 95 fuel in it.....
The fuel trims are reading like -39 for the LTFT and STFT is like normal........ but at one stage one side of the engine went the opposite. When we had the injector issues we had cylinders being flooded by stuck open injectors...... I'm wondering if the o2's or cats are stuffed........ also someone else on the forums here said they had a similar thing and it turned out to be a broken valve spring or something.......... but yeh I'm at a loss and about to loose me sh*t.
It's the 3.0 LFW V6. *shrugs* I don't know.... I've tested all the wiring back and forth to the injectors from the ECU and thats all fine...
