book it into Lexus to have a diagnostic check using Lexus own code reader if you nice they might just do it for free. this will tell you what the exact problem is if its coil packs buy all coils from Lexus and swap them if its spark plugs they recommend Denso irridium plugs. but as i suggested Lexus diagnotics will be best to verify the issue it could be all sorts like sensors, ignition leads, coils, spark plugs..

also dont take this the wrong way as i dont know your mechanical knowledge or background but sometimes if these things are not fitted well they could result in all sorts of problems which sometimes ends up in the over spending of the money one was trying to save in the first place by not going to a good garage/Lexus.

How do you know it's cylinder 1? Have you got a code coming up?

If it was a coil pack they tend to fail in pairs so you could have another?

Change your leads.

Happened to mine.

Have you cleaned your engine bay recently?
