i have a big problem.
when i start my car sometimes the tach needle doesn't go up. then when i start moving the speedometer needle doesn't go up. in order to get it to work i have to hit my dash a lill just above the guage cluster. what does this mean. i'm also throwing a CEL code 67.
i bet the oxy. sensor in your cat is messing w/ your ecu which messes with everything in the car including speedometer and tach...it could also be a short that happened somewhere during a systm install, check your grounds.
Sounds like an 02 sensor short. Take it in, they wil have trouble finding the problem and will most likely change a few things before they figure it out.
But at least it will be done for free.
