Car Having Period

[jinkl]

how come sometimes the car performs superbly
but sometimes i feel like tarak power , wheel spin pun tarak wor
hehe.. but of cos at nights feel better la :)


Old Problem But Still there :

replaced my plugs
and high rpm misfiring stopped
but now im using BP 7ES (not BPR)
at idling , very random timing got like misfiring but very very soft noise.
got any advice and what checkups to do.. and a good mech to go to.

ur ignition power increase (cos ur previos plug kaput edi), then i assume u need more fuel to burn at low rpm. only my wild guess

 

[alvin24]

too rich? also just a guess... coz' i'm running a bit rich at low RPMs, and i'm getting that too.

 

[AlucarD]

jin.. ur plugs are cold type and at idle its rich. Can you smell the petrol fumes sometimes. This sputter is normal ler ... get a good tune. :)

Wah, alvin nice hairy legs man ... :huh:

 

[KeonG]

hehe.. btw, wat happen to ur leg?

 

[jinkl]

will try other plugs and see if this thing comes again :)

 

[flamefox850]

can someone tell me how to see spark plug code name and the grade ? either cold/hot plug ? but yes..no 7 usually a cold one

 

[jinkl]

I think 4 and 5 normal plugs , 6,7,8,9 are cold lor..
i also want to know hehe
got so many types
copper , platinum , iridiums .. bla bla bla

 

[flamefox850]

yeah i know about the number 5,6,7,8 and so on...
but what i want to know is about BPR lar..BPS la..what's that ?

 

[jinkl]

oh i tink its the height and size of the head..
hehe .. not so sure also :P newbie

but my problem is not actually like misifiring
its like once in 3 minutes like that one puff..
then suddenly 2-3 puffs in 2 minutes.. no constant time for it to come.
