t4 poping and farting

[hirstyt4]

Hi All

Am having a spot of trouble with the car

when i put my foot down and it starts to boost it starts to pop and fart out of the air filter and die. I've just bought new volvo spark plugs and still the same

any help please

ps i took the fuel pump out and cleaned the filters and put some injector cleaner in the tank

at a guess id say missfire...make sure u got leads on in correct order.
it maybe a lead breaking down....if u got leads,
if its got coils then maybe a coil breaking down under load,

could be the coilpacks (2 of them around £50 from partsforvolvosonline.com)

i expect its the fuel pump, get one off ebay - easy to replace.
