Civic1.6VTEC

i have searched and not find anything that helps. i have a del sol, with a d15b7 block, and a d16z6 head, i bought the car like that. i have code 22, i have changed the green oil sensor for the vtec, and the vss sensor. my speedo doesn't work, my rpm gauge work until 4k, then it just skips, and the car hesitates at high rpms, but runs fine at low rpms. any ideas?

is this a 5spd or AT?
your vss is making it go wack. or it can be the cluster, those go bad too
22 VTEC pressure valve- check the sensor again, check the wires, check the ecu

it's a manual, it used to have the d16z6, but the previous owners changed it. it's a p28 ecu.

did you check the wiring? reset ecu.

i replaced the vss. and reset the ecu, still same thing. the code 22 appers like 2 or 3 seconds after starting the car from the reset.

then start chasing wires goodluck
