help! sinisinok corolla ko

[1D4LV]

possible culprits (although summary lang ito nung mga nasabi na nila)

- defective high tension wires
- dirty fuel filter
- dirty carbs or injector
- worn out spark plugs

salamat po sa mga info. EFI 4afe po sya spark plug ko naman ok naman po ang sunog kulay brown siguro ok din naman ang high tesion wires, try ko pong palinis ung throttle body.
pwede mong magtanong kung magkano kaya fuel filter nito 2years na po ko di nagpapalit. may kinalaman po kaya clutch disc dito? thanks!

had this prob with my car few days ago though mine is honda matic...

this is what my mechanic did.

1. replace the fuel filter-madumi na as in kalawang na when he tried to clean it.
2. fuel pump-ok naman daw.
3. fuel tank-its still clean no dirt inside.
4. throttle body - cleaned with carburator cleaner.
5. clean the Splugs.

so far ok naman ang auto ko and medyo gumanda ang hataw.

p.s.
FUEL Filter - 350

ign timing 8deg BTDC *idle

spark test at least 25kv

check for codes

Ask ko lang sir if we have the same issue sa car ko (93 corolla; Carbs). Do you experience sa car mo pag naka idle in Neutral, Paiba-iba yung RPM nya. Hindi nagsesetle. Pag tinapakan ko naman and increase the RPM bigla nalang mawala' and babalik naman ulit pag bitaw sa acceleration. and kong naka 1st/2nd gear and sometime 3rd gear pagnag-acelerate, parang mawala yung 'sinok' pero bag bitaw sa acceleration ayun nanaman, inconsistent ung RPM nya pababa- hindi smooth. Ganito din ba yung sayo'?, if so I should check the same thing as the guys have already provided. thanks

You may do the things mentioned before, plus check the carb, it may need overhaul, Kamuning area in QC can help you on this.

sir jayardingo..

1st check mo vacuum lines..ganyan din corolla ko taas baba ang rpm kapag nakaminor check mo vacuum line ng distributor yung sa advancer try mo tanggalin and see kung magstable ang rpm...baka VSV valve mo hindi na gumagana yung may mga hose sa ilalim ng carburator bale parang thermostat ang nasa loob niyan at water temp ang nagcocontrol ng movement..yung ibang corolla nakaclose na ito at may plug na ang lagayan ng VSV valve...
2nd..check mo timing belt baka loose na ang tensioner...
3rd..check mo engine support mo bale 4 pcs ito(front, left,right and back)...eto ang una na dapat icheck kapag may jerking or fluctuating movement ng rpm....yun sa akin after nakita ng mekaniko na punit na yung left at front..presto..nawala ang fluctuation and jerking ng corolla ko...check mo din minsan tanggal or loose lang ang bolt ng engine mount mo...
4th...pacheck mo distributor mo po spark condition check mo website ng Autozone may repair guide sa maraming types of cars including our 4AF.

hope this helps...
