Afternoon gents. Huge apologies for the long post and all the data.
I have a rather perplexing issue with my hilux, ended up purchasing techstream + cable and eventually got it working.
Background - 2010 3ltr D4D, just ticked over 109000km, no issues earlier this year. Drives fine around town, I only noticed an issue early May on the highway after a period of driving, real power loss then the engine and gear lever would shake like crazy once I slowed and came to a stop. Leave it for a short while, it would be pretty much back to normal.
Note - no smoke at all, no cold start knock, only the issue of low power then the engine shake after around 30minutes of engine running (this isn't just under load as while trying to get drivers to work for the cable I sat in the car idling for nearly an hour, first thing I see on techstream are huge injector values in 2 and 3)
While in Mackay recently I got advice to change fuel filter as it could be bad fuel and added a bottle of injector cleaner. Things improved (wasn't slowing on a slight incline!), but it would still do the same after a period on the highway.
With techstream hooked up today and reading these threads I took data for cold start at idle, then warm at idle and at speed, nothing really standing out on the figures. Driving around town for 15 minutes or so it seems fine so I head to the highway. 15 minute drive, fine, head down a rural road up to 120kph briefly to test
, seems ok, slow into a small residential area and I notice the engine shake and injector 2 and 3 are up around +4 and +5.
I take more data at idle, at normal speed and values are slowly lowering. Switch off engine for a while and back on, values are lowering. I drive home with injector values between 0 and 2 roughly, when I reverse onto my drive, injector values crank right up again.
My SCV is the newer, longer style, can't clean that out. Pressure often seems out by a fair bit but willing to listen to advice.
I've done plenty of research but can't seem to find anything quite like this case. Data included below for a few situations. Plenty more available if needed
really would appreciate some expert advice as living in Bowen I don't have many options to see somebody local and hope to save some time and money by doing the hard work up front.
Thanks. Mike
