my car engine bay is shaking after i installed new spark plug wires, how to fix it? thanks

Perhaps one of your new wires is bad and your engine is missing on one cylinder. If you pull the wire on the cylinder that is is already missing the engine won't sound any worse.

Check they are all clipped on at both ends.
Are these the ones that were too long?

I would check to see if all my plugs were tight, then check the firing order.

what do you mean clipped on both ends? you mean the wires cannot be touching each others through the plastic wrap? yes, these are the ones that were too long. Otherwise, everything seem to be running ok, just the shaking that never occurred before the new wires. Since i'm having a compression test done by a shope, will a compression test tell which cylinder is not getting enough spark/missing?

pne of the wires is messed up,, yu will have to find the messed up one and reset the ends.

I was meaning are they on the plug properly. same for the dizzy end.

If you get your old plugs you could use them to find the problem. just change one at a time, ie. you'll always have one old one and 3 new ones.

How to find the wire that makes teh engine miss? you will have to pull each plug wire one by one with the engine running and find which one is screwed up. When the one that is bad is pulled there will be little to no difffence int he engine running smoothly. It will be a very noticiable difference, as when you pull a good one it wil run badly. Whne you pul the bad one, it wil make harly any difference. Then check the end you cut and/or attached the mteal clip and fix it..

You may be able to avoid shocks by wearing gloves.
