sorry ment to put this on v6 tech but i have a 3.8 and i had a similar problem before where one spark plug was disconnected (the cable) this time i checked themagain andone was disconnected again and i pluged it in until i heard the click. but the problem consists, do i need to let the computer recognize it or something? because its running rough i can hear pops coming out of the exhaust and its quite frustrating and humiliating heh. And yes check engine light is on but its been on since i took out the cat 5 months back.

well now it has the same symptoms as before its most likely a misfire but i assured all spark plug wires were connected so now should i replace the spark plug wires? btw my check engine light started blinking today and my car wont go over 70mph i went to kragen but those bastards dont have obd system available and they didnt have the spark plug wires either. I hear a hammering sound trying to speed up. help Please!

You may want to change the plug that had the disconnected wire, as it it may be fouled due to no spark.
