car takes long to pull off with ac on

[zoelikescheese]

what could be causing this?


it only started happening like a month now


nissan tiida
cvt
40,000kms

sounds like you need to service your injectors and throttle body.

[zoelikescheese]

hmm but when the ac off it works fine

[BrotherHood]

How long do you have this car? Have you recently started using the AC often to pick upon this occurence?

With AC on, there is more load on the engine resulting in less driveable power.

[zoelikescheese]

ive had this car for about 3 months and it isnt my first car so i know how much loss of power i supposed to get

this is really unbearable

[Tarantula]

did you run a complete scan on it?

[zoelikescheese]

nope
i came on here to see if anyone can assist me with this problem before i do anything

[~Vēġó~]

did you do any a/c work? top off gas? an overcharged system can cause undue load on compressor, car feels very sluggish when compressor is running and wreak havoc on fuel economy....

[wagonrunner]

IACV to be cleaned + possibly throttle body. What air filter do you use?

yea i topped up gas but that was a while ago


and nope its not the air filter i tried it without the filter already

ok i changed the speed sensors on the transmission and i still have the same problem

i have to mash right down on the "x" to get the car to pull off normal but when i'm driving fast (over 100) it works perfectly fine


i did a scan after i changed the sensors and now i am getting a code "P1550 TORQUE CONVERTER CLUTCH SOLENOID"

i also went by someone else to scan the vehicle and his scanner showed nothing on the transmission but some codes on the engine. He cleared it and it still pulling off lazy

E throttle needs servicing

[Cunupia_soundz]

im getting the same problem..did you get this resolved? some days it happens, others the car is driving perfectly

[zoelikescheese]

nah it still effing up

[Cunupia_soundz]

cleaned throttle body, changed plugs, service injectors...same ting...i wonder if its a voltage issue :\ the idle rpm drops to around 600 sometimes and the whole car shakes....now the car accelerates almost half as fast as it normally did...and i know if i carry it by a mech they will check over the same thing and busss price and problem not solved

i had a similar problem on y11 wingroad.It turned out to be the fuel pump was failing. i did scan it by anil in freeport and he diagnosed the problem. the fuel pump would not show up on most machines/scanners though but anil does a good diagnosis. i not saying this is the problem but i am suggesting to take it to anil.
right now i have to go to anil to raise the idle on the wingroad which i should have done a month ago-similar problem to yours cunupia soundz

[zoelikescheese]

doubt is fuel pump

[Cunupia_soundz]

i tink its either an electrical problem or transmission..i think if it was fuel pump it would have been a consistent problem..thats not the case with mine..btw yesterday i cleaned the maf sensor and its pulling really well now...i hope this solves things and the problem doesnt start back

[Master of Disaster]

If your car is not getting enough fuel it would happen. Take into consideration that when you use the AC the engine require more fuel as it is under load . common factor .or unless your idle control or step up unit is faulty .

Tuners I have a primera wagon that came with a E throttle qg 18 engine & cvt hyper transmission ....for the time it worked it was best in power and fuel...it started losing power and kept getting worse ,took it had it scan at local garages and work done resulting in no change...took it to nissan service center spent 3,000 there and it only lasted aprox two months ....finally I had to replace the engine and transmission...so if u have this engine replace it don't waste money...

well clearly you dont have the same problem as me

update: car doing 130,000km and same problem
considering changing the tranny soon

i HEARD about some ppl having problems with the transmission brainbox resulting in the sluggish pullof. they changed the transmission brainbox and it worked better. i tried this when i had the problem - no change- but mine was the fuel pump. i still suggest carrying it by anil and pay a $150 to get a proper diagnosis.

why do you believe you have an electrical problem?
my situation- I have music in the wingroad and one time a ground wire was knocked out (have 2 o gauge) .the car drove strangely which is when i realised the problem after looking into the engine bay.
hope this helps

i went by plenty mechanics and they all scanned it

codes not showing up

Post a contact for anil

When the AC on does the idle change to compensate for the compressor coming on
