Hello i have hks downpipe,apexi catback,Walbro 255 fuel pump,cold air intake should the check engine light be on with that i just put the fuel pump on yesterday. Have the boost controller but i have the hoses disconected right now running on stock any suggestions on how to get it off.

 

Well, go to a place and have the code pulled. That way you will know what is causing the problem. Otherwise it could be a number of things.

 

thank you

 

keep us posted on your code.

 

well you eliminated 2 of the cats so that could be one of the reasons.

 

Well this is what happened yesterday i had the boost on .12 and so i was at my friends house for like an hour we leave to go out and the light is off so im driving and i get fuel cut in like 3rd and 4th and it comes right on after fuel cut so i turned it down to about .11 and im not getting fuel cut anymore so this morn i go to go out and drive and its off and hasnt came back on yet. Oh by the way some *******s while i was at a bowling alley poured a 2 liter of pepsi all over my blue works i wanted to kill someone and supposibly some girl said it was a bunch of guys in this white like 97 mustang if i see that car holy **** there gonna get run off the road i was so mad last night so me and my buddy washed it off with bunch of hot buckets of water and today i work at Honda so im gonna get my works detailed. Who pours soda and a WRX come on now.

 

That could be your problem. Reset your ECU and it should go away.

 

Driving tonite the light has been off all day and im about 2 min away from my home and it comes on wasnt even going fast or having any boost on just keeping a steady pace. Do you think it would be my mass air flow sensor if it isnt like sealed that good and has a little space between the cold air intake and the sensor? sensor is fine on the downpipe and would the stock boost controller not being hooked up throw the light on or no. Also have another question where do you think i should go with here for mods. thank you for all your posts and help
