Engine Faults Adding Stress Looking for Proper Diagnostics Sharjah

[willamson]

I’m dealing with an issue where my car shows no warning lights, but the engine hesitates under load and the fuel efficiency has dropped a lot. I’ve already checked the basics air filter, plugs, battery condition but the problem still appears randomly. Before I start replacing parts without proper testing, I want a workshop that can perform true expert vehicle diagnostics in sharjah, not just a basic OBD scan.
I’m looking for a place that actually checks live data, sensor patterns, misfire counters, and performs deeper troubleshooting. Many workshops only clear codes without identifying the root cause, which I want to avoid.
If anyone here has had a similar issue properly diagnosed, I’d really appreciate recommendations on where you went and how thorough their diagnostic process was.

It sounds like you’ve already covered a lot of the basics, so you’re right to look for a workshop that can run more advanced diagnostics instead of just clearing codes. In situations like this, live data analysis is essential — fuel trims, injector timing, misfire counters, and load values can reveal what simple OBD scans completely miss.

One thing that helped me in a similar case was going to a shop that actually compares sensor behavior under load instead of only checking idle values. Sometimes the fault only appears under acceleration, and a good mechanic will perform a dynamic test rather than a static one.

By the way, if you prefer understanding systems in a more structured way, platforms like Krikya
might also be useful for staying sharp and analyzing patterns under pressure — it’s surprisingly helpful when you’re trying to think more systematically about problem-solving.

Hope you find a workshop in Sharjah that can give you a proper diagnosis. Let us know how it goes!
