AOA Hassan Bhai you help me with my civic which had a trimpot issue JazakAllah...
Alhamdulillah Milage is good now and there is no engine light no code...
But some times when i start the car and its idle after warming up it randomly starts (sounds like misfiring from the silencer) it does it several times but not every time....
Another issue is while driving the car.. when i come to a speed breaker or any stop... and when i press the clutch padel and leave the Accelerator,, The Rpm jumps to 1500 and stays there for few seconds (15 to 30 sometimes)...this is very irritating as i can hear the engine loud and good like if i am accelerating on purpose....
Following are the things i checked...
- IACV---OK
- MAP--OK
- MAF-- OK
- TPS--OK
- Trimpot -- NOw OK
- ECT---OK NEw
- Vacume Leaks --- apparently ok..(also ok when idle)
- Accelerator Cable is ok and not so tight...
plugs --- NEw
Coil cables--New
I noticed and i feel that something is giving the ECU the wrong readings which make the engine rich only while driving???
as i heard the rpm should drop while pressing the clutch during drive but it rises instead..
Some one told me to bleed the air bubbles from the radiator... i did that and the car was ok for few hours and then again..
Thats why i also changed the ECT sensor..
Everytime i have to reset the ECU and the the problem is gone for a day or two depending upon driving..
Then it comes back without any code.
IF you can help please.. Because i showed it to may people... and service centers... but no one has any idea what to do...
I am from Quetta.
