yudyin and non vtec - thanks, kaso yun problem nun cefiro hndi tumataas, bumababa halos magzero yun rpm, kaso taas ulet idling ng 1t rpm, then baba ulet parang gusto mamatay, nagpalit n nga ako ng gas na 95octane,. sinusumpong everyday pro bumabalik din sa normal yun idling after a while, kaso nakakatakot lng kce parang mamatayan ka, thanks for the concern

norman,

yup ok ang petron e10. sa a32 ko, i can drive conservatively, mga 1.5k shift na kasi walang tope. feeling ko nga ang e10 ng petron is way above 95 octane kasi even on XCS, i experience a little tope. btw, cheaper ang e10 ng PHP2.

M707,

stock height muna. i've seen some a32's on stock springs, doesn't look bad naman. sana lang ok pa rin yung ride.

yudyin,

Nissan's Consult (engine scanner) will diagnose all electrical/sensors, etc. diyan malalaman if you have problems sa MAF, Knock sensor, ignition coil, crank sensor etc. BTW, na try ko na mag HKS drop in filter, parang walang difference sa performance. pero nung nilagay ko sa 1.3 GX, lumakas yung hatak. anyway regarding sa MAF, basta wag mo hawakan yung wire. spray lang ng carb cleaner. pero better siguro if sa casa mo na pagawa yan.

richierich,

consult na siguro katapat nyan. usually free na ang consult if sa casa na rin gagawin ang PMS.

consult ko na nissan gallery, knock sensor daw sir, bka meron kyo alam maklukunan or kun kaya gawan muna paraan? thanks.

**normanenoza** · November 28th, 2008 03:26 PM

i dont think that a faulty knock sensor will give you that symptom. i have done it with my cefiro, tested to run the engine with the knock sensor unplugged and didnt notice any idle problems. the worst that it can give you is tope and bad fuel consumption. magtanong ka na lang sa surplasan, parehas lang ng pang SR20 knock sensor nyan.pero ang alam ko may resistor hack yan but it would default to advanced timing.mahal din kasi sa kasa yan, nasa 6k-9k yata.baka sa surplasan makakuha ka ng 2k-3k or di nila alam gamit baka makuha mo pa ng 100.malas mo brader naka-down ang NB, marami na kasi discussion nyang problema mo pati knock sensor.

**richierich** · November 28th, 2008 04:26 PM

naku sir naguluhan tuloy ako ha, panu kya to sir? every gamit ko sinusumpong yun idle and umuusok maitim and mabaho, pro pag bumalik na sa normal yun idling okay na ulet yun combustion, pinakita rin sken nun mechanics sa nissan sunog nga yun socket knock sensor pro i doubt din nga na dun galing yun saket, para kce kulang sa sunog yun gas, palitan ko din daw yun spark plug ng platinum, yun b talga dapat pag cefiro? kapapalit ko lng kce ngkR sabay change oil, sir bka may kilala kyo second opinion dito, hehe,

yan ang knock sensor sa VQ20 pre.yan ba pinakita sayo?

**non-vtec** · November 29th, 2008 01:57 PM

I bought my Knock Sensor sa ebay. I turned out cheaper by almost 50%. If you can also get hold of a surplus as long as the shop will give you a warranty and compatibility upon installation. I'm sure most reputable shops will. Driving with a bad KS will result to retarded timing and rich fuel mixture.

Check na rin if you had the right spark plug model.
BTW, are there other error codes aside from a bad KS?

anyway i also have a couple of bugs in my cefiro. need your advices as well.

1. The RPM needle jumps at 4-5k rpm. no engine hesitation occurs, just the needle fluctuating.

2. ABS light turns on once in a while after driving. it turns off after restarting.

Sana mag online na ang NB.
