Hi guys,
I'm thinking of removing my SCV soon because I think it's the cause of this particular issue.
Today I (easily) caught up with a Mazda driver doing about 70km/h in a 100km/h zone. An opportunity came up to overtake them so I signalled, pulled out and gave it some throttle. The Mazda also accelerated to 100km/h so I put my foot down hard.
Within a couple of seconds, the fuel rail pressure dropped from over 18,000psi to something like 7-8,000psi. The car wouldn't accelerate further. Turbo boost pressure was still at 18.5psi (thereabouts) but the rail pressure fell right away like it was trying to enforce limp mode. A few squeezes of the throttle brought it back to life momentarily but it quickly dropped again.
I'm thinking it's either the pressure sensor, or the SCV having an issue with the higher flow rate. Because cleaning the SCV is the cheapest option and a likely culprit (247,000km on the clock) that's what I'm thinking of, but I'd be interested to hear if anyone else had a similar issue and found that it was one or the other (or something else!).
As for the Mazda, the moron backed off because a 75km/h bend was coming, which the Navara took at 100km/h no problems, but they slowed to something like 60km/h for it. Talk about confidence behind the wheel.
