    OK first off i know my speed sensor is bad or maybe needs to be rewired since my speedo never leaves 0. My question is when i start the car and drive it operates normally and vtec activates @ 3500. After about 10-15 when its warmed up the check engine light will come on and disengages the vtec(i guess limp mode). If I turn it off n back on vtec will work fine again, can someone give me suggestions as to what could be causing this. I'd appreciate your feedback or personal experience.

    well first the car needs to know its above 20mph or vtec will not work, fix your vss. and vtec should not engage anywhere near 3500 rpm. it should be more like 52-5600

    I was just going to say that lolz. Vtec should be no where near under 5k unless your computer is chipped. Get a new VSS and if the issue continues then it could be your vtec soleniod
