bugeye blasting trouble

[tking_wrx]

Hi, please help, since I changed the oil and fuel filters on my car yesterday and replaced the rear suspension i have had trouble between 4 - 6k, the car dives fine normally but when I put my foot down it feels like the car is hesitating and it keeps backfiring between these revs even whilst driving. Any help is appreciated.

Hi mate, did you put the fuel filter on the correct way? They usually have arrows on the flow direction.....

Hi mate, thanks for the reply, I did double check this and it seems fine, don't really know what else it could be?

It is a strange one.... Was 100% fine before the service?

If check around the oil filter location see of any sensors have been knocked out maybe? Defiantly sounds like a ecu/sensor thing due to the problem only showing on wide open throttle.....
