DEAR WAZUANS; THIS IS MY CAR - FOR THE LAST 2 DAYS; WHEN I SWITCH IT ON AFTER ALONG TIME OF BEING OFF ...... IT PRODUCES SOME VERY FUNNY VIBRATIONS ---- WHEN I STEP ON THE ACCELERATOR WHEN THE CAR IS STILL PARKED AND ON ---- THE VIBRATIONS INAZIDI THEN IT GOES OFF!! I HAVE BEEN ADVISED TO CHANGE PLUGS ---- I HAVE DONE THIS TWICE --- FIRST PUT K16 .. THEN K20 BUT THE PROBLEM IS STILL THERE. INNITIALLY; IT USED TO REFUSE TO ACCELERATE BUT AFTER CHANGING PLUGS --- IT IS NOW ACCELERATING. SHIDA IKO WAPI?? SAIDIENI PLIIIIIIIIZ!! MWS

Ama iko na engine ya tuk-tuk? That's normal lol! I suspect the lead wires, if the plugs are new. Vibrations may be due to 'misses' by one or two spark plugs coz of faulty/aged lead wire(s). Tip: while idling, step hard on the gas pedal n see if the engine initially CHOKES for a while b4 eventually revving up-most likely culprit=faulty plug/lead wire.

Asanteni for the responses..... Thimioni ---- for sure it does exaclty this ----- chocks ---- then either goes off ama inajiwasha slowly .... Now changed plugs ---- checked plug distributor --- had some soot --- wiped / cleaned with sand paper .....but shida persists ..... also refusing to quickly accelerate!!

@mjuaji cars are really simple. If something is not working right, its either electrical, fuel system or mechanical fault. Mechanical faults are accompanied by noises, fuel faults by chocking noises and electrical the car just cuts off quietly. From your description the problem is fuel system. Could be the fuel pump, if it gets dirty and clogged esp if you operate on low volume levels. It could also be one of the sensors or a malfunctioning throttle valve.

@ Mjuaji, hata mimi nilikuwa na shida kama hiyo. It started right after a service so I changed plugs several times lakini wapi... problem persisted. If the plug wires are faulty, try pulling out and returning each plug wire one by one. As you pull them out, the vibrations will worsen and reduce when you put it back in. If you pull out a wire and vibrations remain the same or change very little compared to the others, that lead wire may be faulty. trick 2, clean out the throttle manifold. Remove all the soot build up that occurs in that area and around the throttle valves. This helped my shida quite a bit lakini it did not go away completly. trick 3 - jaza tank ya petroli halafu weka mkebe moja ya petrol fuel injector cleaner. Did this once.Hiyo ilinisort kabisa. Sasa vibrations ni kidogo sana when I start up in the morning.
