changed radiator other day, bleed it no the car has a large missfire with little power deffo no boost, i have not drove it with no water in, has not overheated but i am wondering what is the cause, no water loss from header tank since done rad, no smoke or steam from exhaust, noticed it yesterday but was really low on fuel, put ten in just and got worse, i have a dicky fuel pump sometimes it wont run needs a thump, just wondering if it is pulsing on and off, would this cause a miss/lack of power, will check tomorrow my plugs and things, hope to god it's not the hg's...............any advice is welcomed

Have you checked the fault codes?

Also, what model, what year?

 

No fault codes

1996 wrx Preg 260ps

63k miles

 

if u have got a intermitent pump it would do this sort of thing,my 2.8 capri had same problem car would run but when u tried to drive there would be a loss of power,changed fuel pump problem solved.if its that bad dont use it as you will starve cylinders of fuel and might cause some nasty damage.
