i think it might be a fuel pump or injectors
but they were working perfectly in my friend's car 2 weeks ago, but we changed to try something but nothing happened and they were working 100 % for 10 dayz then the problem starts suddenly

hi everyone, i got a problem with my A15 sohc lanos it takes a very long time to start maybe 3 - 5 min and when i became lucky and it starts every time i tried to step on the gas the rpm lowers till it cut off and when i tried to step the gas to the end i heard a voice of misfire or something like t...

its manual, besides that i didn't come near the ECU nor the engine .
so i am going to clean the throttle and the sensor or change that sensor and try so as to see any changes.
thanks guys for your help,
am going to inform you what will happen

the engine keeps getting high and low as if the idle is not working fine, but i changed the idle and it still doing that, i thought it might be the fuel pump or the injectors, i did put my friend's injectors and pump, nothing changed. so there is nothing to change except for the fuel pressure regula...

finally fixed.
it was the idle control valve, which made the engine cut off when i release the gas.
and the speed meter it was a ground wire under the hood it was cut.
so all was fixed, thank you all for help

he said its absolutely normal,
but i know my car more than him.
it does consume more fuel than normal (not as before)
and the acceleration became poor comparing with old dayz by the same car
so i dont know even if the problem is o2 sensor or ............
its been something mysterious to me

yeah sure a mechanic made the rebuilt !!!

its not gettin hot @ all, even when am running on higher RPM

it was 2 months ago, and it was a full engine rebuilt
and the spark plugs is new and the wires.
but i dont know how to check the catytic converter ????? if it is block or not
i dont know if it is the o2 sensor or fuel pressure regulator or the EGR ???

i have a 2001 lanos,
it consumes alot of gas ( maximum 7 km / L )
and it has a very bad acceleration, specially from a stop, it barely moves

i solved half the problem, i found the speed meter socket form the engine the ground wire was not conducting i solved it, and the speed meter returns to work and the check engine light went off for ever. the 2nd problem which i cant solve it, is the RPM the engine goes down until it cuts off , i thi...

i 've a serious problem with my lanos 2001 1.5 it cutts off when its on idle, the RPM gets getting lower till its cut off when i dont increase the throttle and the speed meter is not working, past it was not working perfectly . but now its not working @ all and the check engine light went on for a s...
