It's not just an OBDII scanner like you would buy at Walmart. You have to have something that will let you calibrate the air suspension. Most guys on here have the GAP IID sold by Lucky8 and others. I have a Nanocom sold by Nanocom. There are others I have heard of that work and a ton of info on the forums and FB groups. My only issue with the Nanocom, and I'm not sure about the GAP, but it is VIN locked so I can't help other's with diagnosis. It was around $500 when I bought my 3 maybe 10 years ago and it's probably saved me easily 10 times that in diagnosis and repairs. I haven't had anyone work on my truck since I bought it other than tires and I let Goodyear replace my front air struts so being isolated as you are that tool will be invaluable.@RobRover88 - Good advice. Thanks for your response. As suggested earlier I need to invest in a OBDII scanner that will tell me exactly what’s wrong. I can start working on the issues I can fix and find a reputable mechanic to fix what I can’t.
Gap is VIN locked as well, but you can hit additional VINs. I do believe there is some basic functions that don’t require that, but I’ve never tested that myself.It's not just an OBDII scanner like you would buy at Walmart.

I am going to be brutally honest here, it sounds like you threw parts at the EAS without really knowing what needed to be fixed. You installed new shocks and new sensors, did you calibrate it after? Is your compressor working properly? Did you check for leaks and did you complete other checks https://epicvin.com/vin-decoder/ford? The EAS doesn't just $hit the bed, and it's pretty easy to diagnose.
I'm not sure why you mention timing chains since that's an issue on the LR4...and maybe the V6. Do you have a MY2006 with the V6?
To answer your question I would neither switch to coils nor send it to the scrap heap. I'd actually fix it! Spend some time troubleshooting, figure out the real issue, and fix it once.
