Hi guys I have a 92 crx del sol vtec, I'm having problems with ,for the past month or so when I drive my Rev taco bounces up n down after bout 3,000 rpm and vtec seems VERY sluggish as if its not moving, what's some things use prefer me with plz help

 

There is no such thing as a 92 crx del sol vtec.
VTEC cannot be described as sluggish. It kicks in or it does not. On or off.
Check your VSS for the tach issue.

 

I'm not a big Honda person but from what I no I hear the vtec but feels like it pushing back no performance or sometimes feels like there's no vtec kicking in what's vss ? Sorry

 

I'm not addressing the VTEC "feeling" because that's not tech. If you can rev to redline then it's working.

VSS=Vehicle Speed Sensor.
