Rb20det misfire?

[Cooldrft]

Put a screw driver on to the injector + listen for the clicking "so you know it's opening".
What does the spark plug look like when you pull it out ?

What revs is the miss fire? when the turbo kicks in or all the time?

Fuel pump....

Were i work we do some tuning and have a few fuel pumps there. I'll try1 of them. It has the miss on idle but when you increase the rpm above about 2000 the miss doesn't seem to be there but yet still not much power????

I'll try the injector tonight to see if its opening. The plugs are all the same looking. There's no difference in wear or anything that shows a bad cylinder. I cant remember what heat rating they are but they are Iridiums. Could the engine be getting to hot and causing them to break down because of a low heat rating?? They were changed before i got it

Sounds like a fuel pump to me aswell lad....!

Ok update...

I've replaced the fuel pump with a Walbro fuel pump and a new filter. She's feeling more responsive but that hasn't sorted my misfire problem on no.6 yet...

I tried to check the injector with a screwdriver but it was had' to tell. Didn't sound like there was any clicking compared to cylinder 1. So i ran the engine and unplugged the injector. No difference at all!!! Now i know there's spark so i'm wondering should i just pull out the injector and check it?

Or have i maybe missed something and some1 would like to offer me some constructive advice and criticism

Thanks alot lads

try swappig the injector to another cylinder and see if problem follows if so dodge injector if not problem could lie in injector wiring or no pulse for injector to open......
