This is normal for the boots to be stuck on it is a very tight fit to begin with and the heat that is generated around them cause them to stick. Try rotating the boots back and forth twisting action as you pull up.If this doesn't work there is a tool available to remove spark plug boots at most autoparts stores.

Were is the ignition module located on a 1999 gmc Yukon


Instead of spending money on parts, you should get a book and troubleshoot the circuit. It could be the pickup or the module in the distributor, or other electronic components.

I have a 2002 gmc yukon denali. When i accelerate slow its fine but when i do it hard or pass someone it pops really loud toward the front right. and will keep doing it until i let off.


Hello and welcome to FixYa!

As a first course of action, I strongly suggest that you replace the spark plugs for I suspect that you have fuel flooding.

The spark plugs fails when they are corroded, covered with carbon, have big gaps or just faulty. It's like you have fuel but not enough current to burn it down for the spark plugs is failing. Have it replaced and this could do the trick.

Hope this helps and thank you for using FixYa! Have a good one!

I have yukon 95 . its engine doesnt oerate will it comes with black smook


Probably engine is misfiring. Check spark plugs and wires. Check distributor cap and rotor.
Check spark at plugs. Should be a blue spark and not yellow. A yellow spark is weak ignition coil.
