Hi guys, I've not been very active on here for a while because I was thinking about selling the Accord though I have still been browsing in the background.
Car is a 54 Exec CTDI tourer.
I've felt that it has been a bit lacking in power for a while, but I also knew the exhaust manifold was cracked so didn't look into it until after that was sorted.
I was just going to trade it to we buy any car, but decided to keep it for a bit longer and so sort a few problems out.
Started by getting another manifold and had that fitted last week, which got rid of the fumes in the cabin, but power was still less than normal.
I've got Torque on my phone so used that to monitor what was happening.
Power always seemed to drop off around 2500-3000 rpm and watching a full acceleration run in 3rd gear showed that the maf sensor readings and boost dropped as I felt the car hold back. MAF dropped from 150ish to 90ish and boost from 22psi to 10psi ish. Both would then climb again but slowly.
Then about a day later the car suddenly developed a loud wailing noise, sounding like the turbo and I suspected a boost hose had come loose but all appeared fine.
Now the car won't boost at all, struggles to get to 60mph and struggles to 2000rpm when driving and won't rev out in neutral either.
Noise has now gone too, can't hear the turbo.
Also I get no black smoke, no fault codes or anything.
Things I've checked:
Boost solenoid is sucking at idle and pulling on the actuator rod.
Air intake is clear.
MAP sensor clear.
EGR valve appears to be working (was working fine in Torque before this).
Current thoughts are vanes in the turbo are stuck or maf sensor.
At the most the car is now producing 1psi of boost.
Fuel filter is a Honda one and has only done about 6k but I've got a new one on order anyway.
Any other ideas? Starting to wish I had traded it now before I started spending money on it.
