P38A down in power

mrtayto · Sep 22, 2020

Car seems to be well down in power(2.5 DSE),has been down since i bought it in april but haven't had time to do much with until today when i changed 3 intercooler hoses out for silicon ones,I cleaned out the intercooler,replaced the MAP sensor and also replaced the small hose between the the MAP sensor and the inlet manifold,
it still doesnt have any power untill about 3000 RPM.
I have a nanocom and it's not showing any error codes for the engine
Anyone any ideas what i could try next.

A V8

Better oft working with compression you got rather than bolt in a V8 and worry about where it’s all going

You should get power at around 2,200rpm.
You got an auto by any chance

What mileage you at, are most things original?
Could just be dirty fuel filter or dying lift pump is common.
There is a load of info available about the state of your engine if you have diagnostics

You could try taking a trace with the Nanocom. MAP values changing? ECU temp OK? Turbo waste gate sticking? Intercooler flushed?

With ignition off? No. With it on you can hear it running.

ignition on.can hear it running nice and smooth for a second or two then it starts gurgling like its pulling in air from somewhere.

Cannot recall gurgling. Does it stop after a bit? If you take the fuel filter off and bridge the fuel pump relay do you get the required amount in Wammers Technical Section post?

Think outside, no box required.
