why is my mechanic saying that spark plugs are the most critical part of the car?

May be, but not for sure. These intermittent issues point to electrical fault more. Check spark plugs, HT lead, starter relay (main culprit of this issue), then CKPS (second main culprit of this issue), then fuel pump but its quite unlikely.

You can use it perfectly normal if you are not losing air even after week time. That means there is no minor leak and tire is fit to use. Its quite normal.

Looks like throttle body need clean up or cable wire plastic pipe is little rough. Clean both of them, if still fluctuate its an electrical issue may be coil or better hooked up with computer and see the fault code.

Ideal RPM should be 700, there is something wrong with spark plugs aor coil. Check first plug and then doubt coils.

Hestitating means while shifting you got jerk: that is gear issue, if its mild change the gear asap with filter and see if it fix the problem. Hesitating means once you shift the gear, in that new gear car hesitate to pick and move then its more tricky. Could be gear (40%) and could be engine like spark plugs, wires, engine oil and all.

Check all the fuses and relay may be some are gone for door control side. If not look upto door sensor or mechanism which tells ECU to flash door ajar light. BTW explorer are full of "electricry".

I can see that you change my thinking Interesting idea of putting same thing differently, that i never knew before that Alternator are made to resist water (i learned something today). And i like too to fix the root cause than the temp solution. Well said edino. thanks.

Change the radiator fan clutch, its easy fix. It looks it got short and thats why its running full time at same speed. It supposed to get on/off and also with two speed one normal, one VERY HIGH LOUD Speed.

I doubt that, that will ever launch in Dubai, as our stealer brings regular model on which they have sure shot returns. &(#@#$

After changing, proper balancing isnt done. It must be from iranian guy you got this changed. Get tyre balance from some authorized tyre dealer or eppco emarat fix plus guys, they are good.

Check the compressor and AC gas leak.

service is not the cause, but cleaning with water inside the engine bay without covering the alternator with plastic is the ONLY cause of dying.
