Hey guys i got a problem with my B16A3 from my Del Sol, and it just dies out when i pass 2-3k revs and thats not even in gear; that is in neutral as well. When the car starts it doesn't even sound like an exhaust it just has this (psssssssss....) sound coming from the tail pipe. Could it be the stock intake? Old Fuel Filter, or something else that might have caused the problem?

The car started to feel sluggish when i drove it yesterday afternoon just cruising, and vtec did not want to even open up. (You hear the crack, but you dont feel the pull). So could that be a bad vtec solenoid?

Im new to this, so im just trying to still search things out. Im not a mechanic either, i only know the basics.
