CEL code 43 - Fuel Supply System
Everything is stock, except for AEM intake. What could be the problem?

 

When did you install the intake?

Reset your ECU and see if that works.

 

I already reset the ECU, its been in there for while already.

 

Car start at all?

Any running problems? If the fuel presure stays in spec, it's usually a bad o2 sensor.

 

Well It runs fine on 1-4th gear. when i hit the highway on 5th the light comes on it stays on till i come to a stop and park. when i try to turn it back on it'll just sound like its trying but won't spark. i cheecked the code, it came up as 43. after like 5 minutes it'll start again. ?
