[seekers282]

hello guys..i need help..car went heavy like no power,it change to lower speed but getting slower when going up hill..i got boost reading..any idea what could be wrong?

[seekers282]

btw..problem..no power under acceleration,even i put off from pedal and press again..still no power..it gets even worst when going up hill..it change to lower gear..but..im getting even slower..leak vacuum hoses?

sounds like your vacuum hoses are ok if you have boost, if its blowing more black smoke than normal,
remove engine cover and check boost hoses especially blue one picture, also clean your MAF sensor
which is located near the airfilter box and held in place with 2 x torx screws
Disconnect the battery for 30 mins as well to re set the ECU

theres no black smoke or smoke visible..could it be my turbo ?

[seekers282]

or could it be not enough fuel ..should i bleed my fuel line after top overhaul?

Sounds like limp mode to me Seekers ......

Resetting the ECU by reading what the faults are and then clearing the codes will restore your power loss.

If you can write down the codes, then you can see if the same ones come back again if the same thing occurs.

The ECU will log all sorts of fault codes, and Nissan will check and reset on every service, but if yours hasn't been to Nissan for a while there may be old codes logged, which have nothing to do with your current power loss.
