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.

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]

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?

[normanenoza]

advise ko sayo pre.pwede kahit ang copper type plugs sa cefiro.pagkakaiba lang nya sa platinum magpapalit ka lang every 5k-10k kms ng copper plugs.ang platinum kasi good for 100,000kms.life lang hindi performance. kung black smoke na mabaho, lean mixture ang AF ratio mo. better check your oxygen sensor and fuel pump na rin.

tanong pre, napalinis mo na ba throttle body mo?napa-check/adjust mo na ba throttle position sensor (TPS) mo?yan kasi mga part na may direct influence sa problema mo.

and kung every cold start lang naman problem mo pwede rin may tama na ring yung ECTS (engine coolant temperature sensor).yan kasi nagbabato ng signal sa ecu na wala pa sa running temp yung engine mo kaya kailangan nya magpa-agos ng mas maraming fuel. experience ko naman sa faulty ECTS is hard starting kahit mainit yung makina.

[normanenoza]

kung ayaw mo ng maraming hassle pre, dalin mo kay speedyfix. pm mo sya dito sa tsikot. expert na sa cefiro yun kasi si antonboq na NB forumer na cefiro ang auto sa kanya palagi nagpapagawa.

[non-vtec]

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.
