hey guyz,
i have a vitz 2001 automatic & its facing a problem.. in cold whether like of these dayz when i start my car on PETROL usally in morning, engine dont run properly, it produces a sound like phak,, phak,, phak like dat of a 2-STROKE engine and even if i accelerate it in Neutral the engine only produces sonds but no proper resoponse on its RPM and if i switch the gear to D or R engine turns off.. On CNG it all do the same & my car also shakes...
To solve this problem i have already,
changed its fuel filter,
removed the CAT converter,
changed all Oils & air filter,
tunned engine several times on both CNG % PETROL,
and other side works,,,, but of no use...
Daily i have to leave the engine running for 7-8 minutes,, until its blue light of cold engine goes off... AFTER that engine runs fine, no sound & perfect accleration...
Again if i start it after 2-3 hours from engine OFF it do all again...
Dont know whats the matter with it so i need suggestions from some experts...
Looking forward Storm to help me out...
Thanx in advance...
