Engine diagnostics in Al Malaz

Al Malaz runs on cars that have already worked through fifteen summers. What we get called to here is rarely a dead engine. It is a stumble pulling away from the lights on Al Sitteen Street, a rough idle on a cold January morning that clears by ten, or a check engine light that shows up one week and disappears the next. By the time somebody rings us, three people have already given three different answers. Our job is to settle it with measurements.

An intermittent fault on a high-mileage engine is almost never solved by the code alone. Stored history and the freeze frame tell us what the engine was doing when the fault set: cold or hot, idling or under load, running rich or lean. From there it is measurement. Relative compression across the cylinders, injector balance, misfire counters cylinder by cylinder, and fuel trims at idle compared against the same trims at 2,500 rpm. A long-term trim that pulls positive at idle and settles under load points at unmetered air, not at a failed sensor.

The first thing done at your kerb is electrical, not electronic. Battery under load, alternator output, and voltage drop across the main earth straps — because corroded earths on an older car in this dust invent faults in every module at once. Only then the pre-scan and the stored history. After that the engine itself gets looked at by hand: intake hoses gone hard with heat, vacuum lines, wiring that was repaired badly years ago, and the connector pins the code points at. Component tests come last.

You hear the price of the diagnosis before anything begins, quoted on its own. If the cause turns out to be something we can put right at the kerb — coils, plugs, a hose, an injector, a connector repair — you get that price too before a spanner moves, and nothing is added to it afterwards. Payment in cash, by card or by bank transfer. If it needs a lift or a cylinder head off, we tell you plainly instead of stripping an engine in the street. We work every hour, Ramadan and Eid included.
