Hi every 1!After a long time i found this forum to benefit myself and others by disscussing my problem. I own Vitz2003 and i got CNG fitted before one and half year. but the problem with this car is that it does not go over 115 km/h on petrol or cng and when after a considerable time it goes over 110km/h and even then i can not sustain that speed and the speed starts decreasing automatically with the same push on accelerator. and when it comes under 100 km/h then shifts back into D3 automatically if i push a little harder. i heard from some 1 that there may be a problem of throttle body(i dont know what it is). if plz some1 can help me out. i have change the fuel filter, spark plugs, and all related stuff even the fuel pump too. but still there is no improvement. it looks like the engine is very suffocated or like there is too much load in the car. if some bady can help me i will be really grateful.thanks to alltake care and bye byeee
Go to some good silencer shop, ask him to check the presence of catlytic converter, ask him to take it out that box, that must b blocked.
If the problem presist after removing that, plz give a feed back for further solutions.
i think it could be the exhaust problem....car ki dholki mein kachra(carbon) aagaya hoga...check it out and get it changed ....
i have personally experience taking the car to 130km/h with AC on and 4 ppl sitting including me, try turning OFF the O/D and see how much she goes
Like few suggested i would first get the silencer checked to see if it's chocked or not get the whole lining checked
very odd, either you have activated the Overdrive or your catalytic converter is choked. i've got the same model vitz as your asd mine had crossed 170 with laughing gas (Nitrous Oxide).
well never had experience of automatic
but the manual has blasting power....even and xli was not able to get away from us
yaar tellu...swap the engine with gli 1.3 enigne..and it will be good
please listen to logas as he is the cng expert and trust me vitz goes well over 140km and definetley ur cars catalytic converter is chocked and when ur done with ur exhaust then u can do further amendments......plugs and wires wont do any good at this stage
I am facing the same problem.Please suggest me any mechanic or shop in Lahore where my Vitz's catalyic converter can be removed.
