From Kia to Mercedes: It’s All Just Physics Under the Hood

I choose to work on VW, Audi and Mercedes but that’s not all I do.

I CAN work on Kia, Toyota, Ford, Chevy, Jeep etc.

Because as we know a lot of this stuff was built on global platforms from at least the early 2000’s.

I remember reading a piece about the MK 1 Ford Focus and how it was a breakthrough because it was a global platform.

So from Fiat wiring being in just about every Chrysler product to that Ecotec GM engine being in a lot of the Chevrolet or whatever else it appears in, I feel I’ve seen most of this stuff, and what I haven’t seen is quickly summed up by applying basic common theory.

3, 5, 6 ,8 or even 12 cylinders, they all need fuel, air, compression and a way of igniting before they can do anything.

My point being it doesn’t matter what you work on, if you apply the basics and do it right the rest is easy and it’s not a question of what badge it carries.

Misfire no Codes – Suzuki Splash 1.2L Petrol K12B

What’s the problem?

This Suzuki came into the workshop with an intermittent misfire. It wasn’t evident on tickover or when I’d snap the throttle while stationary. But when I drove it any distance, I could feel it. Okay, so that’s the customer’s complaint confirmed. The next step was to connect a scan tool and check for diagnostic trouble codes (DTCs).

No codes?

Despite the misfire, no DTCs were stored. With no codes, a different diagnostic approach will be required to prove the fault. I’m suspicious of an ignition coil but I want to prove it to be sure.
