I recently bought a 1995 Monte Carlo V-6 and when I come to a stop my car begins to shake. I looked under the hood and realized that it would miss on the 5th cylinder. I put new injector fluid in and changed the spark plugs and it seemed to be running a little bit better but it's still running on only 5 of the 6 cylinders. I also noticed a funny smell. I have checked the vacuum hose with starting fluid for leaks but did not find any. Does anyone have any idea what else it could be?

You should also have a light on dashboard telling you to check engine. If not you may have something else wrong. But by the syptoms I believe the coil pack has gone out. The coil pack for a good replacement is not too expensive. It would probably be wise to have it taken in and properly diagnosed. As It could also be a bad cam sensor or even, I hate to say it, a bad computer not sending signal to fire on that coil.

you may have a bad injector(seen alot of them go bad) you may have a bad plug wire. if so, replace them all. you may have a mechanical problem internal to the engine. do a compression check. should have about 125 psi, or higher.. you may have a bad ign coil. seen very many of these go bad. pull each plug wire off at the coil 1 at a time, engine off, obviously, and look at the coil tower. anything other that bright shiny metal is bad. alot of these coils corrode, and take out the plug wire. i am curious to know how you figured out number 5 cyl is the problem. it takes reasonable knowledge and equipment to know that. if you have both, then this will be a walk in the park to figure out.

have you do a compression test,leak down test,vacuum leak test using a smoke machine . the most common problem on MONTE CARLO is bad ignition coil pack.

Fouled spark plugs.
Loose spark plug wire boot.
Spark plug wire arcing to ground. (split insulation)
Cracked distributor cap.
Spend $30 and an hours worth of your time.
Check those first.
It probably hasn't had a tune-up in years.

so a strategies as i understand there are no push Rod seals or you're refering to valve stem seals and those require specific kit and adventure to alter you will not commonly substitute them for the duration of intake manifold gaskets substitute.
