Hi all. So I have I missfiring 986 under acceleration and it does try to cut out when I come to a standstill.

I’ve replaced the MIF, the air filter, engine oil and filter change, plugs and I’ve cleaned the inlet manifold, I’ve had a look for basic leaks and found nothing, my Durametric tool shows no engine faults.

Is the next best thing to do - to check the fuel pressure with a fuel pressure gauge or to do a vacuum leak test with a smoke thingy? Sorry I don’t know it’s name 😁
