Hello I have a 2003 2.5 Navara twin cab it is giving me some problems for the last while it is down in power not so much when its cold but when it warms up 1st & 2nd gears are fine but when you use 3ed & 4th it is very bad no power and chucking quit a lot but not all the time but most

Ive tryed changing the filters and gave it a good service but that did'ent help any ideas please

does it feel like it's stalling at around 2500-3500 revs and won't go above 65mph?

Not so much stalling more chucking but your right you would'ent get it over 60 but when you get it into 5th it go's fine I just cant under stand it mate...

sort of like stalling but without the engine cuttin out.

when you say you get into 5th and it's fine, do you mean to can give it the boot and it'll go without holding back?

Yes that it..

sounds like the engine managment system is playing up a little to me. i would have said your intercooler has gone as we have had the same problem but we had the problem in all gears.

Whats to break in the intercooler though? Its a passive unit that just passes air between the turbo and the inlet manifold, cooling it along the way - no moving parts!

If the Navara engine had a MAF I'd have suggested that first...has it got one?

Could be a problem with the EGR.

Try asking at www.nissan-navara.net there is a lot of info on there.

the actuall intercooler itself, ours cracked and we had similar problems.

so i assume it was blowing air out then? how on earth did it crack, was it a faulty casting or something?

i don't have a clue, i was puzzled when he said the intercooler is cracked. it could not get proper compression.
