Hello from Norway!
I have a 1997 with a few mods that recently have developed a problem.
First off, I have reasonably New Nozzels, front mounted intercooler, 3" exhaust exept for the dump pipe from the turbo that is still the original one. I also have a Tunit adjustable chip. Now 280000 kms and I run Royal Purple 5w-30 oil. And KC air filter.
I should also mention that it has an ARB Sahara winch bumper with winch,OME 2" lift kit,Air lockers front and rear, Automatic transmission, 285/85-16 Cooper tires, steel rock sliders and underbody armour, so it has a few extra kilos to drag around.
The engine mods make the other mods less noticeable, and it drives OK. Fuel economy is not great but I can't expect enything better, Things being as they are. I can sneak it under 10l/100 kms, but normal economic mixed driving leaves me at about 12-14l/100 kms. That is with the famous egg under the go-pedal.
However, recently it has started to lack a bit of Power. I notice it most driving at highway speeds, when going up hills, most of them I can keep above 85 km/h, keeping transmission in over dive and Lock up engaged. Or could. Now I usually need to disengage overdrive and let lockup engage in 3rd. Even then it may struggle a bit. I'm now talking about trying to keep fuel consumption dom, if I floor it ofcourse it will move. With a decent amount of black smoke to go with it. It just seems to be more sluggish than it used to be, although it has never been a racer by any means.
I also has developed a very noticeable leap in perfomance at about 2200 rpm. If accelerating normally, at maybe 1/3-1/4 throttle, and rev Counter hits the magig spot, it will jump to about 2500 rpm and you can hear turbo really waking up. I turned the Tunit chip back from setting 7 to setting 5, and it was less noticeable, but it is getting worse also at that setting.
Any ideas on where to start looking? I thought I'd start with checking or blocking the EGR valve, and maybe see if the intake is clean or full of soot and gunk.
Anyone else experienced the same sympthoms?
Thanks
Stefan
