    Just a local guy that my mechanic uses. No printout of flow or anything. Rpms are being read from the EVC screens and Diacom

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    This motor is possessed. Injectors were numbered and sent out. Guy said they were 30% clogged. Checked fuel filter and it was clear. Checked regulator on fuel rail and there is no filter screen in it and it was clear. Put 1357 injectors in 2468 spots and vice versa. Went out to run and...

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Well it is the CE (I assume means cats and electronic something). The computer shows the 4 O2 sensors and bank one and bank two fuel trim percents. Pulled the injectors and am going to send them back to be checked yet again. Going to have to wait until Monday for that though.

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Took it out early this morning. Engine would only go up to about 4500 at full throttle. Fuel pressure at 52 at idle and 54 at full throttle. Shows no misfires at that speed but you can tell something is wrong. Tried a few more times, rpms max at 3k and starts back firing. Use computer to...

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Still playing around with this issue. Swapping parts between the two engines and it doesn't seem to be ignition related though we honestly don't know. Didn't realize the evc (evc-d) shows faults on the screen! We are showing MIL 126 FMI 14 on both SID 4 and 7. Can't seem to find anything on...

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Just ran it again with a separate fuel tank in case the fuel was old. I didn't go full throttle to see if it would misfire below the rev limit. At about 4800 rpm the misfire kicked in. I'm using NGK itr4a15 5599 iridium plugs. Been using them for years with no issues (these are new plugs...

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Mechanic is ruling out rev limit as he spoke to his Volvo contact and they confirmed that isn't how it limits over revs. Still not sure which way to proceed at this point. I did notice when I took it out once, no codes were thrown my first pass at full throttle. After I slowed and turned...

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Surveyor took my boat out for a test run and while running at full throttle for about 30 seconds, the warning chime came on and power was cut to the starboard motor ( s/n A204563). My mechanic hooked it up to the computer and it shows "cat damaging misfires" on cylinder 4 and 7. There were...

    EVC Key Error

    I have a 2012 5.0 Gxice that will give me a 'key error' when I first turn on the battery switch regardless if the keys are in the switch or not. I have to wait for the power to shut down to the evc (I assume there is a few minute time to save power) and then I can turn the key and start the...

    Spark plugs for 2012 5.0 GXiCe 270R

    Hello, I am looking for the recommended spark plugs for this motor as volvo has their own part numbers for it and I'd like to pick up something locally. I can only find autolite xp605 but would prefer to stick with an NGK plug (finding multiple to cross reference so not sure which one). Best I...

    Volvo gxice 5.0 dps-b drive goes down but not up

    Hello, just put my boat in the water and I'm having trouble with the starboard drive. The EVC says power trim failure and wont allow starting the engine without an override. The drive tilts down all the way but I am unable to get it back up. The evc doesnt seem to know where the drive is and the...
