I am rephrasing my question. Does anyone know what are the symptoms of bad sparkplug wires? My spark plugs were replaced 10K miles ago, they´ve been checked out and look ok. However, the car shakes a little bit and the iddle is not smooth, it actually looses power when taking off from stop. The iddle regulatrors were checked out also and are ok; all vaccum hoses were revised also and are ok. Any input is appreciated.
Have you tried resetting the ecu's? Disconnect the battery, wait a few seconds, reconnect it and then start the car. Don't touch anything, just let it idle for about 15 minutes. It is best to do this after the engine has sat all night. What this does is lets the ecu's relearn the warm up parameters of the engine. Anytime you disconnect the battery you must let the ecu's relearn the parameters. The ecu's do not have an internal battery, so any time the power is cut they loose the memory, sort of like a car stereo. Try that first and see if it helps.
"Losing power when taking off from a stop" is sometimes called "bogging down," which is usually associated with a fuel/air mixture problem (typically too rich) or a timing problem. I'd suggest finding a shop that has an exhaust sniffer as a good first place to start with your trouble-shooting. In contrast, bad Ferrari spark plug wires tend to show up problems at mid and high rpms, instead of at idle or low rpms as you are taking off.
