2012 Ford Ta**us V6 Customer states vehicle runs poorly after having coils and spark plugs replaced by mechanic. After diagnoses, only the no.3 coils was replaced, the no.2 coil isn`t firing due to a broken coil connector and the no.4 coil has high amperage due to a shorted coil. Only the boots were replaced, not the coils. The fix is all new coils and spark plugs.

Diagnosing vehicles isn`t as simple as plugging using a scan tool, reading codes and replacing parts. It requires a serious understanding on vehicle operation, electrical schematics understanding and the proper equipment to aid in pinpointing the cause of the problem. Case in point, this waveform comes from a 2017 Kia Forte that has had the parts canon fired at it and still has a loss of power, long crank time and also lack of interval oil changes. The middle hump tells the tale. This vehicle has an advanced timing issue that is reflected with the exhaust valve closing early.

2017 Ford Transit (My vehicle) This vehicle started exhibiting a very slight glitch when driving around 70mph, scoped the 2 signal wires, noticed the red trace was glitching at times. A new throttle body is the fix .

Informed customer of the problems with the 2.0L.

This is carbon buildup on valves after 100k miles on a GDI engine. This can cause a range of issues such as rough idle on startup to cylinder misfires. If your vehicles is a GDI ( gas direct engine) you may want to have it serviced.
