This is a bit of a strange one, so bear with me.

For the last year or so, my EML has been on in my car. It always referred to Glow Plug 3.
Just ignored it all this time as car had started fine.

Decided to sort it the other week so done a resistance test on all 4 glow plugs and sure enough plug 3 was dead.

Got a replacement Denso plug and fitted it. Ensured everything connected correctly then used Torque app to clear fault codes and EML went out.

Few days later EML light comes back on. Tells me Glow plugs 1,3 and 4 are faulty.
Take off the glow plug rail, blow inside all the connection points and check plugs 1,3 and 4 and all are fine.
Re-fit the rail and clear error codes.
Started several times that day and no more issues.

Next day issue returns.
Any suggestions on where to go from here?

Thanks. Will give TPS a ring when on my day off tomorrow.
Do you know if you need to cut anything for this, or if it's connected via a plug?

Done a lot of searching on Google but seems to vary depending on what engine and car it's in.
