Could be a bad plug even know they are new one might be bad , first check in the dark for any arcing (blue sparks) coming from wires might be a split in one of the spark boots ,make sure on there good,also a chance you put wire to wrong cylinder

What is the recommended spark plug for a 2000 2.4 litre grand am...? Thanks.


You could have asked me in the original post!

2.4L L4 engine= Gap: 0.050" (1.27mm)
3.4L V6 engine = Gap: 0.060" (1.52mm)


Edit:
For 2.4L L4 engine

My owners manual lists AC Type 41-942 (Platinum Plug) Gap: 0.050" (1.27mm).
But http://www.acdelco.com says AC Delco part # 41-942 spark plug, platinum plug is GAP .060" without RPO (RC9).

Chang spark plugs


The first thing to remember is only change plugs on a cold engine, or you can risk damaging the cylinder heads. Disconnect the battery, and remove the sparkplug wires from the plugs (pull the boot, not the wire). A slight turning of the boot may aid removal; be sure to keep the wires in order. Use a socket to remove each spark plug from the cylinder head. Check for oil or black soot, which may indicate an engine problem. Check the gap of the new plugs before installing; the recommended gap is .060" - you can get a simple gapping tool at any auto store. Thread each new plug into the cylinder head, being extremely careful not to cross-thread them. Snug them down; do not over-tighten. Re-attach the plug wires until you hear them snap on. Reconnect the battery and drive.

Cylinder 1 misfire 2003 chevy impala.. My car started running rough all of a sudden today. like the engine was shaking. took it to auto one said cylinder 1 misfire. what does that mean & what should i...


a number one misfire means that the number one cylinder is no longer working as good as it should or is not working at all. The number one cylinder is on the back side of the engine on the passenger side. 1-3-5 are the three cylinders in the back.

Three basic things can cause a misfire.
1. a bad spark plug wire
2. a bad spark plug.
3. a bad injector.

Remove the sparks plug wire from the spark plug and remove the spark plug. Inspect the inside of the wire and the outside of the plug to see if there is any carbon tracking. it will look like black lightning bolts. If there is any carbon tracking replace the plugs and wires.

Check the spark plug gap. It should be around .060". if its over .080" the plug is worn out.

Check for spark with a spark tester.

the fuel injector is a little trickier.

Start with the things above and let me know what you find and we'll go from there.

What would be the best spark plug to buy for an 05 Equinox with 60,000 miles on it and what would the gap be?


!st let me say your engine is not due a set of plugs until 100,000 miles, and to change them any sooner is a waste of money.

If you still wish to replace the plugs use ACDelco Spark Plugs, here is the part number and gap.

How do i change spark plugs


  1. Expect spark-plug work to be tedious. If this is your first time, plan 3 or 4 hours after engine cools (or 1 hour on several days), allowing 15 minutes per plug. It is harder than changing air filters, fixing flat tires, or starting a mower.
  2. Consult your vehicle's manual. Look up where your spark plugs are, how many you have, the correct "gap", and the size socket needed to remove them. Also write down the vehicle's make, model, and year. The gap can also be found on the emissions label under the hood.
  3. Visit your local auto parts store. Find (either by looking up in the provided reference book or by asking an employee) the correct spark plugs for your vehicle. The store also has socket wrenches, plus spark-plug sockets (with gasket), and socket-extension rods or swivel-joints to reach recessed plugs.
  4. Find out (from the reference book, the packaging, or the employee) if these spark plugs need to be "gapped". Some modern plugs should not be gapped (but others can have different gaps, depending on use in either 6-cylinder or V-8 engines, etc.).
  5. Park vehicle, turn off the engine, and open the engine compartment, to cool for hours. (WARNING: After running a car for a long time, the spark plugs can be the hottest part of engine! While it can require several hours to cool enough, it can require several weeks to heal burnt skin.) Especially with aluminum-head engines, let cool to room temperature to reduce the probability of damaging the threads.
  6. Take (if needed) a wire-gauge spark plug gap tool and adjust the distance between the two electrodes. Between the electrodes is where a spark is made. One electrode will be an L-shaped piece of metal (hook), the other a metal prong centered directly across from it. Set the gap between the two electrodes, from .028-.060 inch, such as .035/.040 /.043 /.050, as in book (see Tips below).
  7. Collect tools & new plugs (perhaps in a tool-tray). Remember which direction the socket-wrench switches to reverse/unscrew: wrench might not be visible when working back plugs.
  8. Check fit of new plugs inside wrench-socket gasket. If new plugs stick to rubber gasket, consider removing gasket with screwdriver in square hole, to just use tape. Like taping screws to a screwdriver, the socket can be taped to spark plugs (not the threads) with scotch tape, for easy release once inside the engine. Otherwise, have pliers to pry the socket off new plugs once installed.
  9. Locate (with the help of your manual or a repair manual for your vehicle) the distributor spark-plug cables/wires. The number of wires will be equal to the number of spark plugs your engine has. Often these wires are red or black, and will be equally divided on opposite sides of the engine.
  10. Using masking tape, mark each of these wires for where they connect. Don't rely on memory: if interrupted, easy to forget, and engine can run rough with crossed plug wires. For 8 cylinders, deducing plug connections is almost impossible (120 choices for 5 wires) -- in that case you must contact an expert or study wiring guides.
  11. Remove each spark-plug cable, pulling the caps (to avoid breaking cable wires). Caps should come loose by very intense twisting/pulling (avoid jerking/hitting fingers).
  12. Using compressed air, pressurized engine cleaner, or a brush, clean all debris from around the plug.
  13. Using a spark-plug socket, remove each plug from the engine, and replace each with a new spark plug. Don't over tighten (usually just 1/16 turn, after finger-tight).
  14. Replace the spark-plug cables on the same plugs they originally came from, and remove the masking tape.
  15. Remove tools near engine (beware the moving belts), close your engine compartment, and start your vehicle.
I hope this helps.

I change the spark plug and after starte to shake ann act weir and check engine light came on


Did you gap the spark plugs, or did any of the spark plug wires get damage while removing them, or did a spark plug wire get crossed,the engine light is most likely a cylinder misfire, I would check or replace spark plug wire's.
