My car is skipping i have replaced my coil packs my plugs and wires injectors and vaccume lines still skipping when im at idle and driving down the road

SPARK PLUG WIRES

First of all, even though the Issue says Coil Pack, that does not necessarily mean the Coil Pack is Bad. It could be a Loose Connection, it could be a Bad Wire, it can also mean a Bad Spark Plug or fouled Injector but to answer your question...

The Coil Pack is located under the Plastic on top of your Engine and Directly connects to the Spark Plug. If I was you I would Swap the #1 and #3 Coil Packs and see if the Fault Code follows the Coil Pack. If it does then replace the Coil Pack. If it stays with the Cylinder, I would be checking the Connectors, Wires, Injector and Spark Plug.

Is the check engine light on ?
The idle speed problem could be the idle air control valve, and the rough running problem could be fuel pressure or dirty injectors.

First thing I would look for is a disturbed vacuum line which will cause rough idle. When replacing coil packs, you have to remove covers, etc. so when vacuum lines get old and dry, even moving one slightly can cause cracking, so look for loose or cracked vacuum lines around where you were working on engine. It may just be loose hose. Good luck

Repair Shop--- you installed too many parts already,
on a guess with no testing

I'd suspect a sticking injector--car should have set the check engine light. Read the code(s) to progress further. If the coil pack were a problem, it would not be likely to fix itself. If the codes indicate an injector problem, try an injector cleaner in the fuel--worst case, replace the bad injector. The codes should indicate which cylinder to change the injector.

The problems you are describing indicate to me that you likely need to replace the coil pack that runs from the spark plugs ,and the plug wires end up at it.It also may be the spark plug wires,get a water bottle and spray the wires after dark and if you get a light show from them then replace them,if not,replace the coil pack.

What engine? Sounds like maybe timing chain jumped or it is very lean.

The injector could definitely trigger a misfire code, but you also mentioned that you had a mass airflow sensor code , that code code be responsible for te sluggish moment of the vehicle and rpm going up and down. However if you have a misfire onCyl#6 and the coil and the plug is good the ONLY other thing to cause a mis-fire would be the injector. To check the injector get a NOID light, you can get one at almost any auto-parts place. To use unplug injector plug from the bad injector and connect it to NOID light the light should have a steady PULSE/ligt flickering. If light flickers fine then injector is bad and will need to be replaced. If light doesn't flicker or flickers intermittently then you may have a bad wiring to that injector. Check if wiring is good, then you may have a bad cam sensor or sensor gear. Good Luck and contact if you need more help. Thanks for using FIX YA
