If the wires have the correct resistance and are in the right order the only thing I could recommend is making sure the plugs are AC Delco. Wouldn't hurt for the wires too since I've run across a lot of bad ones from Bosch.

AC Delco - GM
Champion - Chrysler
Motorcraft - Ford

Do you know if the plugs were changed, a bad or broken plug will also cause rough idle and slow acceleration?

Tuned up car changed 02 sensor full tank of fuel still running rough


Oxygen sensor only report the condition of the engine the rough running condition can range from a worn sparkplug wires to worn sparkplugs to valve problems to injector problems. with the cadillac deville a tune up should be the first attempt to smooth the rough idle with the inspection of the cap and rotor cap and rotor do have a tendancy to arc internally and create misfire so does sparkplug wire that can leak spark voltage to ground and create misfire. the spark plug wire especially if they are brittle and hard can create issues

My 98 Sunfire is idling very rough. How do I check if it's a miss fire or something else. just recently replaced fuel filter and plugs


did you just replace the plugs or replace ignition wires, rotor, and cap (or) ignition coils if applicable? and you check whether its fuel or spark problem by running the engine and taking the plug wire off the spark plug and seeing if there is spark and noting any change in the engine, if the engine runs rough(er) or stalls then you know there is no problem spark related with that cylender, if no change occours when you take the plug wire off the plug then you know there is either a no spark condition (you will be able to see if this is the case) or if there is spark and it is a fuel problem. self explanatory, if everything you test for passes then you probably have internal engine damage. recommended that you use rubber grip pliers when you take the plug wires off while the engine is running, do not ground yourself. Hope this helps! Joseph.

Car starts and runs fine until it heats up then it runs rough


Check spark plugs. The back pressure may be causing one or two to fail to spark and ignite the fuel mixture. While at it go out at night and start the vehicle and watch the spark plug wires for sparking to ground. If you see a spark form a spark plug wire change all spark plug wires.

Did you properly gap the plugs when you changed them? Improper spark will cause really rough idling at low RPM like that.

Ford Escape 3L 2002 Rough idle


generally, when the engine is washed, water gets trapped behind the spark unit and stays there, creating a shorting path for spark plug current. best to dis-mount the spark unit (follow plug wires back to source) and dry and clean it thoroughly.
