Help~ i need to plug off the MAP sensors ...

[desmondlim90]

why i need to plug off the MAP(Manifold Absolute Pressure) sensors hose from the manifold then can start the car...and if no on the air-cond the car will jerk if on the air-cond the car will not jerk
if the MAP(Manifold Absolute Pressure) sensors hose not plug off the car cannot start!!

why you ned to unplug it ?
it's a must sensor in order for the car to run smoothly...

i guess you just having an idling problem...not MAP sensor problem...

have your checked what is the diagnosis error ?
have you cleaned up your throttle body ?
have your check your A/C compresor is it working correctly...if they any compressor leaks, compressor clutch problem or clutch air gap problem... ?
or maybe any burn or non-working A/C relay...?

just my 2 cents...

check your firing system and fueling system...

 

[desmondlim90]

all is good...
and when accelerate in 1000k-3000krpm like miss firing(in cold condition) but reach 4000k the rpm will easily reach 9000k... why like this??

that i dont know la but till 9k haven cut yet..
i need to install 10k + rpm meter liao.
then know in how many k cut zzz

 

[chinozie]

smell fuel very big ?
how many pressure (psi / bar) of fuel are running on ?

 

[desmondlim90]

if not wrong the past owner of the car change the nozzle more big than stock nozzle..
and how i can know the psi/bar of my fuel???

 

[chinozie]

install FPR = Fuel Pressure Regulator

to check what's is the fuel lean or rich...
to prevent engine knocking...

 

[desmondlim90]

why my car hard start??
izzit throttle body spoil??
throttle body sensor??
can u gv me an answer??

 

[chinozie]

maybe...

fuel too rich...plug have too much black carbon...
too much fuel...but less oxygen...engine choking...
hence...hard to start...
