Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / September 2007Engine Shaking after changing spark plugs & Wires ??????
I have a 1994 Oldsmobile Cutlass Ciera with a V6. I had my spark plugs & wires changes yesterday due to rough idling. Yet, when it was all said done, the engine is now shaking a bit. (Was not happening before). We tested to see if the all the spark plugs were firing and they were. I pretty sure its a misfire somewhere, because the car sputters when I come to a stop. I plan on getting a diagnostic ran to confirm my theory this weekend, but I was wondering if anyone had this problem before and could offer advice.

Thanks Check the firing order, two spark plug wires swapped will definitely do this. nate > I have a 1994 Oldsmobile Cutlass Ciera with a V6.

If it is shaking, as you get with misfiring you can confirm which plug is causing the problem by selectively removing one wire at a time from a plug.

Most manufacturers recommend against open-circuit testing on today's cars - as in removing a plug wire while the engine is running. It can cause a voltage spike that can ruin electronic components. Use a neon inductive tester, or put the car on a good scope. One other thing, unlike Grampa's six-volt, '49 Ford with the 20kv secondary, a 50kv zap from GM HEI across one's chest CAN stop your heart. It'll surely raise havoc with a pacemaker, too. check firing order!!

My father once had a tune-up at a tune-up shop. (This was back when cars actually needed tune-ups.) They gave it back to him with 2 wires crossed. Great service. |
