Hey guys,

As some of you may know that i installed my SOS Stage 1 Supercharger in Winter. It was tuned in January and was working perfectly fine. I have stage 1 kit with AEM EMS v2, 1000cc ID Injectors, Test Pipe, ACT Clutch and ap2 flywheels.

Couple of days ago, my car out of no where started running very Lean. The AFR gauge goes to 16-18 in idle or somethimes cruising. Sometimes the car runs fine but sometimes when i try to accelerate, it feels like the car is hesitating/choking/stuttring.

Sometimes when in Idle, if i turn the A/C on or even push the window button up or down, oil pressure drops to 15-16 (which usually stays between 15-25)and cars feels like its going to shut off.

First i thought it was due to bad gas and emtptied out the gas tank and filled with fresh gas. The problem still exists.

Can someone help me and tell me what is making car run so lean and what can i do to get it fixed.

all help will be much appreciated.

 

What happens when in boost? does it stay lean or does it operate properly.

 

It stays lean for a while and then goes to normal.

 

You should be logging while this is going on. Its going to be your best bet to find out what is causing this.
