2004 Envoy: Plug boots not seating properly

Changed the plugs on my 2004 Envoy - now have at least one hard miss - feels like plug(s) not firing. Have rechecked the plug boots and very difficult to tell if they are on the plug completely. Anybody got a good way to check.

Rubber boots with metal cover w/coil spring at the plug end.

Changed spark plugs now no spark 2003 envoy


Coil packs was the problem in the first place. When a spark plug misfires, the high voltage goes no where and the coil starts to deteriorate. After prolonged misfire the coil will not make the hi voltage necessary to fire the plug. Replace the coil packs.

Erratic idle


Couple of things come to mind. I take it you have the I6 engine?? In some models, the big plastic resonator on top of the plugs has a hose that plugs into it at the bottom. Check for this, I've missed it many times and get the same symptoms. The other is making sure the sparkplug boot is seated correctly on every plug. Not being able to see the connection way down in there makes it difficult to know if it's on the plug correctly. It's a common problem. Take each boot off and reinstall, listen and feel for the click to make sure you have the correct connection.

There can be other reasons for misfires beside spark plugs/coil, such as a bad injector, low compression in that cylinder, burnt valve seats.

My 2004 envoy sputters when I start it. I just changed all six spark plugs and it does the same thing. Check engine light is on. Handheld computer is logging misfires, P106, P128 codes. Lags and will...


The P0106 code indicates a problem in the MAP sensor area. Did you reconnect the MAP sensor connector after the plug change or seat it properly?
The P0128 code has to do with the coolant temperature not coming up to operating temp fast enough, this usually means the thermostat is stuck open.

2004 chevy envoy changed the sparks plugs not there isnt any pressure and it is missing


I6 engine I take it? A very common problem is for the coil boots not to seat on top of the plugs correctly. Double check these, I see this error all the time and have done it myself. Feel or listen for the little click when re-installing the boots. Also, make sure your pcv hose on the plastic resonator is re-attached along with the tiny hose that goes to the fuel pressure guage, another thing that is commonly missed. Again, been there made that error.

Whats the firing order diagram for a 2004 envoy 4.2 connected to a obd it says number 3 cylinder not firing need to know which plug?my son replaced several not all! hard to get 4.2 straight 6 cyl


The number 3 plug is the third one back from the front of the engine. They are numbered in order 1,2,3,4,5,6 front to back, this is the cylinder numbers not the firing order. Firing order is 1-5-3-6-2-4 .

My car is a 2004 Subaru WRX STI, and the code is cylinder 1 misfire. what does this mean? and how do i fix it? Thank You


That means that the fuel being injected into cylinder 1 is not being ignited at the proper time.

Check your spark plug wires for damage and make sure that the plug boot or coil assembly is seated properly on the plug.

If all of the above are correct then it needs to have the spark plugs changed.
