one of my thread regard to MISFIRING
check with bro Red Bean Bun
hey brudder... ya man the misfiring... I wanna write a case study here to share with all of ya...
1) car shrudder like mad on day 1... assumption is jb petrol (shell).
2) then minutes later car resume normal... go sports mode at nite... everything fine
3) Day 3... car suddenly vibrate madly again... went ws and replace coil#6 (using bmwhat app diagnosis)...
4) cos it was late n ws has no stock on new ignition coil, so plug in used one (different model from the remaining 5
5) car was fine and running good (oki.. quite normal)
6) then on cny eve... I itchy finger bought a new coil frm ES (same model as the rest
7) remove coil#6 and plug the new pencil coil in...
8) F*ck my bloody itchy finger... car start vibrating like day 1...
9) drive slowly back home and parked car and cry... no more transport for cny...
10) think and think... only solution is to wait for ES to reopen after cny.. prepare to spent $300+ bucks to replace all coil...
11) Then today... cny day 1, I tulan... open bonnet... start swapping coils and try... worse... diagnosis came up with more coils failing n misfiring...
12) and when I twist one of the coil... the engine died.. mf*cker...
13) my brain go crazy...
14) Finally I unplugged all the coil wiring plug/cable... and plugged them back ... real hard pressing... and start car...
15) My mofo is back... MY MOFO IS BACK!!!!! Okay guys.. the problem is the pic below (look at the red circle)

guys... make sure the gap between the plug and the coil is super pressed tight. the car is old liao... vibration and heat might have push the plugs loose over time and that happened on my coil #6... hence... sometimes even mechanic also dunno wat happen... so solution change all coils... of course all will be unplugged and back... and they shld knw how to press the cable head in hard... a
and if the connection is loose or weak due to wear and tear... progressive resultant will be not so powerful performance ... bad fuel consumption... vibrations... lousy idling... and finally misfiring and stalling...
p.s. this is juz one of the possible diagnosis.. and solution... I am no mechanic... but was lucky enough today to solve my misfiring problem.
