Hi, ive done a search and need a more simplfied lingo to check the timing on my EF 6cyl.

Recently got the car back after getting a timing kit installed and it wouldnt hold idle, so i reset the ecu that night and slowly after a week it has something that resembles an idle but not good enough. Sick of it nearly stalling when i turn into carparks.

I want to check the mechanic's work. I know i have to check the following:

Firstly i turn the crank until the mark on the balancer lines up with the timing mark on the block.

And i guess i also check that the cam gear is within 3mm above the head, but i assume this isnt the whole story.

If these two marks are lined up good what position should the valves & pistons be in?

Cheers!!!

Ok ive checked both balancer and cam gear marks line up, but most importantly i need to know how to check if piston no.1 is at TDC...

Is there a tool to check tdc that screws into the spark plug hole or somthin?
