Interesting - good to know
OK, I think I've found one reason why the car is so gutless.. now, let me tell you a little story
Firstly - I should say while I don't consider myself a genius with cars, I have re-built a few more or less from the ground up (most recently a ~420hp Nissan 300ZX and a ~250hp Toyota MR2 Roadster) so I think I know what I'm looking at when it comes to petrol engines, but diesels are more of an unknown.. anyway, extrapolating my knowledge and what folks here have posted, I went looking for the MAP sensor.
I think this car has had a new engine at some point (tell-tale yellow marker 'X25' on the engine cover) and .. I suspect someone didn't write down what hose went where
This, if I'm right, is the EGR valve:
Which, I would assume, would be hooked up to an EGR solenoid (i.e. a small black box with two hose connections).. only it's hooked up to this - which I'm putting good money on being the MAP sensor, am I right?
Now, I wondered where the EGR solenoid had gone, if that's the MAP sensor.. so I peered into the gloom and found this dangling free:
Which is attached to two hoses that disappear off to the inlet manifold - I presume these are supposed to be the manifold reference for both the EGR valve and MAP sensor?
So if I'm right, what I need to do is unhook one of the manifold reference lines from the EGR solenoid and attach it to the MAP sensor (probably the one that double-backs around the dipstick tube!) and then attach the EGR valve line to the output of the EGR solenoid. Right?
If so - does it matter which manifold reference goes to the solenoid vs. the MAP? I see one has what looks like a one-way valve or filter in-line?
