Lack of power is it the turbo or the cat..?/ - 1993 Isuzu Trooper

Seals leaking on turbo see if the shaft through the turbo has up and down movement if so replace turbo.

There can be an array of problems that can illuminate the EPC lamp on S-Class 220. A few of the most common faults with these are : HFM sensor, turbo or blocked cats. the best way to check the cats are the remove them and tap them on the ground and if dust falls out then the cats are damaged, if OK, you may have to plug into a diagnostic machine.

If that model of Range Rover is turbo charged I would be looking at getting that checked.

suspect a blocked catalytic converter...lightly tap on it. listen for debris falling, put you hand in front of the rear exhaust pipe to see if the pressure feels fairly forceful...cats are expensive...check a locally trusted mechanic if you suspect that it is bad....some times he has a good used one lying around....also if the engine has'nt been seriously tuned lately....then have it done FIRST!!! hope this is helpful

may be a bad fuel filter or pump.

does the starer click when u turn the key,u could have a bad ground from the batt to the body

Hi,
This is the second Vw I have responded to in a fortnight.
Your lack of power I presume always happens when the glow plug light illuminates?
This is because it is causing over combustion to vaporised diesel, I would be looking in the Glow plug timer and relay, as for Turbo lag, I run a E34 6 cyl Bmw Diesel and the Turbo only kicks in around 2,500ish so maybe yours is a little tired or in need of a check up?
Hope this helped,

Please remember to rate my effort!

turbo must have a problem or remember tro vehicles have turbo lag. . . usually mitsu's turbos start giving power around 2500prm - 3000rpm. .

but usually on older turbo diesel mitsus the turbos are the first to go. . . .

check out cat converter
