Separate names with a comma.
Yeah. I suspect that after the supposed fix, either there was a leak that was overlooked until too late, or else the pump wasn't pumping for some...
I understood they did EGR through valve timing that retained more exhaust from the previous cycle than conventional timing would. That technique...
Air follows the usual ideal gas laws so PV=nRT. Meaning the pressure of a fixed quantity of gas times its volume equals the quantity of gas times...
You were correct. That's been the case for many decades, since long before (R+M)/2 was a thing.
It means there wasn't much restriction in the EGR cooler yet. "Inequities in degree of clogging in the intake manifold EGR passages" shouldn't...
Not perfectly, though. All gasoline engine exhaust contains carbon particulate. GDI engines are worse.
If that's true, why am I getting EGR restriction test results of 18.4 kPa and above at over 131k miles?
Interesting. In ACC state, I measured only 1.51A after it settled. 1.75A in ACC with radio on at moderate volume. 0.71A in OFF state with any...
Based on what symptoms, if any? It might be needed, or they might be trying to rip you off with unnecessary work. More information needed ...
Really? That's not what my ScanGauge says. More like 190°F to 195°F if the engine has been running continuously long enough to open the...
Mine does, in the form of a Scan Gauge. That doesn't mean I'll be watching it at the right moment if it ever shows abnormally high temperature.
How early? Are pumps sold by dealers now more durable than my 2011 one?
^ A much better plan
That's right, and those algebraic relations aren't as complicated as people might imagine. If one doesn't "get" them, one can't understand what's...
And GDI particle emissions vs. the limits on diesels? Why should they get a free pass?
Wikipedia and Guinness both say there have been only two confirmed human deaths caused by cassowaries in the past century---in 1926 in Australia...
Uh ... Do we have particulate limits for gasoline-powered vehicles now? That was a moot issue until DI.
And he specifically discourages close drafting as a hypermiling legitimate technique, contrary to the definition stated earlier in this thread..
I've never seen a rubber "bleeder cap" (which seems an inappropriate name for a hose or nipple) there. It must've gone AWOL before I bought my...
Not even to legitimate auto parts outfits? That's a little strange.
