Salam Fellows, Hope you all are fine. I am again here to discuss and get your precious comments on the issue i am facing with my corolla 1.6 GLi 4AFE.
Symptoms: (1) Engine is giving starting problem, not in the morning but subsequently after wards at the day time, even the engine is turned off recently. Engine seems to get started for a very short period of time (in miliseconds) then get turned off automatically and afterwards require significant starter motor effort (i mean time) to get started.
(2) RPM is low at below 1K (despite 3 or 4 time tuning from ENERCON) and when AC is turned on, RPM comes down to 400 and engine starts vibrating. Moreover while driving on AC when clutch is pressed to stop the car on signal RPM rolls down significantly and engine shuts off.
(3) Engine power and throttle response is low at 1.5K RPM. In short the power and throttle response i used to get on 1.5K RPM now comes at 2.5K RPM.
(4) When car starts moving from dead stop engine gives a sudden jerk at around 1.5K RPM both on petrol and CNG in first and 2nd gear (and the same thing has ruined engine foundations)
Diagnosis : ENERCON guy is of the view that the car is having faulty throttle body or sensor (dont know what it is). The situation described above is same for CNG and Petrol
Please dear fellows help me the issue described.
Thanks
