I took it to the shop, it I believe the valve is the problem

Before you go and pull the head, pull your injectors and have them checked or just buy a low mileage set and throw them in. Replacing the injectors is a pretty quick and easy job. That's what mine turned out to be and there is a whole thread about it here somewhere.

I also thought it was injectors, but it wasn't injectors..
So we are going to check gas pressure today...
Hopefully it's not something big problem

I had misfires on cylinders 1,2 & 3.

Crapped myself.

Turned out the plugs were working loose. Carbon build up on coil packs pointed the way. Was a huge relief.

Hope yours turns out to be so simple and cheap.
