Miss fire
Lads just last week found a 1993 import wrx that had been dry stored for 11 years non runner but not a drop of rust .I got her started with a new tank of fuel and fuel filter changed all the fluids plugs coil packs put a wide band sensor and boost gauge in change all the vacuum lines went to give it a test drive as it idled fine Then disaster she miss fires like a crack head with an ak 47. First thoughts we're check the timing done this and it is on point am not sure we're to go next Tried her with and without maf cleaned throttle body and idle control Would it be worth a compression test b4 I check the injectors/ecu she idles fine if you tap throttle hard she revs fine holds boost but if you slowly apply throttle she pops and spits ?? ? ? Pluss the starter and alternator failed the 3rd time I started her

Right new cam belt ect fitted cheers john. put all the front mount inter cooler pipes on started a right treat sounded perfect then turned her off after a 30 second run just to triple check all looked good went to fire up again but now she just turns over FFs will it ever end lol. I took out the crank sensor and noticed a dent in the bottom am sure this is my problem. I can only find ones that have a plug on the sensor it's self mine goes all the way to the throttle body b4 you can unplug it any ideas were I can get a new one ?
