Why is my car running rough with new spark plugs and wires?
I have a 2003 Ford Taurus SE and it was running rough, so I put in new spark plugs and wires and it is still running rough. I was wondering what is wrong with my car.
Many things can cause an engine vibration or rough running.
Since new plugs and wires did not fix the problem, that was not the problem to begin with.
BTW, throwing random parts at a vehicle hoping to fix a problem is a time consuming and expensive way to diagnose a problem. Diagnose it properly first and fix it right the first time.
Right on Jay, and unfortunately, there are a lot of incompetent mechanics that do the same thing, and we get to pay for all the parts the car didn't really need.

- Why is my '98 Ford windstar is running rough after a tune up? I changed out the plugs and wires and it ran good for a day or two but has a lot of hesitation at lower rpms but if I speed up it goes away. Also have a gas smell in my air conditioning when I'm stopped but not while driving. Can anyone help? I'm tired of putting money in this thing.
- Why did my car start rolling on its own when changing the spark plugs?

I had it in park, I quickly ran to the drivers side and put the E brake on but I still don't understand why it did that. It drove fine after that and so did the parking brake but wtf?
- I bought an Actron CP9125 Code Reader to try and diagnose a rough idle at cold start on a 98 Ford 4.0 engine. The rough idle had not caused? The CEL to come on. I plugged the code reader in with just the key on and pressed read and the little asterisk goes half-way across the screen one time and stops. I press the read button again and it reads 0 codes. I was thinking it would scan multiple times to check for pending codes or other issues. I tried it with the engine running and the same thing happens. Is this code reader operating properly?
- Would bad spark plug wires cause a check engine light? I just changed the valve cover gasket on my car. Then when I tried to start it, it started violently shaking and the check engine light turned on. The only thing I could think is that maybe the spark plug wires broke when I took them off. Would that cause a check engine light? It's a 2002 Ford Focus ZTS with 150000 miles
