Hey all, ive bought a wrx estate 99 100k miles turbo but it had been stood for a while its in need of a good service. It's now for some reason started holding bk on accelerating ive started the service by changing the plugs to NGK irridium but thats NOT solved the holding bk problem. Im thinking of changing the leads next but im not sure what leads to use ive been told about magnecore??? any tips or suggestions of what to do next greatly appreciated

Check for fault codes, my guess is MAF sensor

Hi , I have heard about the maf sensor is that the same as the air flow sensor by the air box?

hey ive took off the air filter and the air flow meter and gave them all a good clean with filter/carb cleaner but its made no difference but i did notice that when accelerating there was a poppin/back fire from the airfilter area. CAN I test the air flow meter on it's own??? Also when starting the car from cold the engine was running lumpy is this to do with the AFM or could it be ignition leads coz there the next on the to do list.
