Assalam-o-Alaikum Amir, Waqas, Amin and all !
I have been away for a while now(and that's hopefully the longest we can go with our beloved car without a problem :p). I am back with a new but not unknown issue.
I am facing RPM drop at idle, the engine doesn't go off but the RPM falls almost down to dead and then the engine accelerates up itself. But this causes missing in low gears(the car gives jerks in the 2nd gear at low speed). The pick is awesome, the drive becomes smooth too in top gears.
I conducted a self analysis and find out that the plug wire 2 and 4 is not passing the same amount of current as in wire 1 and 2. Can it be because of the wires? Can it be because of the coil grips as i have repaired both the grips for broken wires my self and the 1 nipple on both the grips is loose but still in contact with the coil slot.
Consider the fact that i got my car computer tuned and censors zeroed and diagnosed yesterday(all the censors are working fine). The car became smooth there after the tuning but i experienced the same problem today.
