Have you checked the condition of your MAF sensors? do they need to be cleaned.. a vacuum leak wont give you a rich tune but bad MAFs could be reading

Have you checked the condition of your MAF sensors? do they need to be cleaned.. a vacuum leak wont give you a rich tune but bad MAFs could be reading higher making the car think there's more air than there actually is.. squealing noise could be belt or the harmonics of the engine itself in the exhaust... I know my exhaust makes a similar sound to the Decel hiss around that RPM, however I'm running FI RTP with 200 cell ultra high flow cats welded into them.
Other than what BGTV8 also mentioned I'm not too sure what else it could be.. |
