Alright so, this week I was spirit driving and all of sudden the intake noise got loud and there was no vtec power. But vtec does engage.
I pulled over asap and checked my CAI, filter, hoses&clamps, motor oil etc. Everything looked fine.
So drove responsible under 4k rpm car drives smooth under 4300rpm (my set vtec)(regular torque and power under 4k)
Once vtec hits, my CAI is 4 times louder. and there is no power. but the rpm can go up if I keep on the gas, have not.
Theres no engine light, and no error codes on flashpro.
Theres no weird engine noises from the engine. AFM is good fuel trims are good.
What is likely the problem?
What should I try first?
Let me know what info you need to help solve the puzzle. Thanks.
