If replaced incorrectly the vehicle will miss fire and run poorly. I think that routing of the wiring is important, but that is mostly a style based issue. Wires need to be routed away from heat stuff, like manifolds.

Replaced spark plugs on a 2004 Explorer. Car became loud and tinging and eventually died? What could be wrong?


It is possible that you have two or more plug wires on the wrong spark plugs or one of the wires fell off the plug.

Does a 2006 corolla 140i have spark plugs


Hi,
Yes it does. I found a site with pictures detailing how to access the spark plugs for replacement. (recommended every 60,000 miles) Plug gap is 1.1mm. Remember to dissconnect wiring and replace plugs one at a time to eliminate the chance of connecting wrong wire to wrong plug position. Wiring must be connected exactly as removed. Check out his page, requires minimal tools and labor.....Please rate this answer! Thanks, Mike

Misfiring after replacement of spark plugs and wires


If it wasn't misfiring before. Make sure you have the proper gap on the spark plugs. Make sure you have the wires connected in the correct order. If you have the old wires, you may want to end up trying those one at a time to make sure you don't have a defect wire either.
Thank you,
Lee

When I accelerate, the car has a hard time getting up to speed and the service engine lights flashes three or four times then stops


Without using an OBD scan tool to read the computer error codes causing the CEL to come on, the best guess is that this could be as simple as a misfire due to old or defective spark plugs and wires, or even possibly just a loose spark plug wire. Check that all the spark plug wires are attached securely. If yes, you should consider replacing the spark plugs and spark plug wires, You can do further diagnostics by pulling the spark plugs and inspecting them, and also pull the spark plug wires, inspect the terminals, looking for signs of wear or corrosion, and test each wire with an ohmmeter to verify that its resistance is in spec. If you replace the spark plugs and wires and the problem persists, let me know and we can take it from there.

Replaced coil, spark plugs,plug wires, rotor and rotor cap, and the part under the rotor (forget the name) car has a miss when idleing and when getting on it, NAPA said the spark plug gap should be .035,...


if this is a four cylinder engine,the plug gap is what NAPA told you,verify you have the right plugs and gap,next remove the cap again and verify the plug wires are pulled into cap where they will lock in.

Rewired ford taurus spark plugs and when turns on it jumps what could i have done wrong?


If you replaced the distributor cap then there is a high possibility that you put the wires in the wrong firing order on cap.

If all you did was replaced the plugs, then I would pull each one out and recheck the Gap sizes with a feeler gauge. Also check to see if the spark/coil plug wires are touching metal or each other, which can cause the spark to arc out of the wire and never get to the spark plug. If I suspect an arc and do not see a physical problem, I wait until nighttime and look under the hood while engine is running...they stick out like a sore thumb. Also make sure that you did not put the wrong plugwire to the wrong spark plug.

When you change your plugs, you should also replace wires, cap and rotor.
