Customer Question
Hi ***** ***** ,have...

Hi ***** ***** ,have a 96 terrano tubo non intrecooled. loss of power. Sometimes wont get over 60ks. , automatic, foot is flat so gearbox cicks down but no power. if i back off it will change to next gear but guttless.If i come to a stop turn off engine and restart ,power is improved,but still not as it should be. Checked ALL filters, clear lines no air, feels like fuel starvation but the flow to IP is good. When im having trouble with foot flat in neutral it will only max at 2500. restart and it will max at 4000 rpm

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

Bad economy,

Hello

1st check the connections to the EGR valve, if either the vacuum pipe of electrical connection are damaged / corroded then the EGR can be on all time which certainly will hurt performance. Its also possible that its a fault with the EGR valve so its worth removing the valve and cleaning it out with brake cleaner, if it looks particularly clogged then replace it.

If this is OK then check the small vacuum lines to the turbo and its connected control solenoid on the bulkhead, any cracks or leaks can give turbo issues and its best to have the boost pressure measured actually measured with a boost gauge to check that the turbo is healthy and that the sensor is reading correctly

If its a variable vane turbo (they’ll be an actuator on the turbo body - but not a wastegate) then check its vacuum pipework as above and check the connections to the diaphragm / solenoid valve

Also worth checking that the glow-plug relay is switching off as they can stick on and leave the glow plugs also on - on some cars this can force it into limp home

Also worth considering adding a bottle of injector cleaner into the tank as a clogged injector nozzle will reduce power and give poor combustion - the next stage on from this is to remove all the injectors and have them ultrasonically cleaned and flow checked

Also check all the high pressure hoses post turbo/s for any split hoses or cracked metal pipes, also check the ends of the intercooler as its not unheard of to pop the end caps off under high boost.

Cleaned Egr all seems good there
Have boost gauge on turbo, all good.
Removed and inspected pickup from top of fuel tank, all good
Ran new 8mm fuel hose from tank to fuel filter, replaced exit hose from filter with clear, no bubbles at all.
Put clear hose from IP to return fuel line, getting some bubbles there.
Took it for another run, bit under powered than normal but not too bad, got progressivly worse over 20ks until it would not rev above 2000rpm and big power loss, it will pull up to 2k but then just no more.

starts perfectly, fires on first compression.

when it would not rev with foot flat , got someone to pump priming pump for all they were worth in case of fuel starvation, revs did not rise.

Hello

Ok thanks for the extra information

This could be a wiring issue as things tend to expand when hot and its possible a poor or partial electrical connection is being pushed apart on one of the major sensors so check the connection plug and wiring to the following;

Airflow meter

Crank position sensor

Cam position sensor

O2 sensor

Throttle pedal position sensor#

if this is all Ok then I'd consider replacing the cam position sensor

Finally found small leak in fuel line just before injector pump. Found it after i fitted an extra electric fuel pump just before fuel filter. Fuel was then under pressure rather than suction and a leak was soon evident. I did not find your answer helpfull and have been charged $5 thats ok but then $23 on 2nd and another $28 on the 12th feb. Please refund $50 , thanks
