My car is giving me a headache any advice would help.?

This is my original question.....

I have a '92 Nissan Sentra 1.6L Manual Transmission. It has started to Idle really rough and drive rough as well while driving until it gets up to speed. I have put new spark plugs and wires, has a fresh oil change and everything. A friend of mine taught me how to check the spark plugs and listen for the change in pitch all but 1 changes and that is after the new wires and plugs. Checked to make sure everything was done right but still doing the same thing. Any ideas of what else?



So far I have a new distributor cap on it now, new rotor. No change. Still nothing in the one cylinder. Somebody also mentioned to check the compression in the cylinder. Now is that only something a mechanic can check with proper tools or is it easy to do.My car is giving me a headache any advice would help.?
Checking compression is easy, and your local parts place has the tool you need to do it. They aren't that expensive. It goes in place of the spark plug; you crank the engine a few times and see where the gauge tops out. It should be within about 10% of all the others; if it isn't you may need valves or rings.



But before you blow some money on that, try this: take out that one spark plug, shoot a teaspoon or so of oil into that cylinder, and put the plug back in. Fire it up. Did that fix it? If so, it's rings. And no, that %26quot;fix%26quot; won't last.My car is giving me a headache any advice would help.?
You can purchase the tool to check the compression in the cylinder.... it goes in place of the pasrk plug and can tell you whether t is good or not. You can find it at any auto parts storeMy car is giving me a headache any advice would help.?
this same thing happened to me on my truck im pretty sure that a couple of your injectrues are going bad in itMy car is giving me a headache any advice would help.?
assuming you checked for spark at that plug, than check that your getting fuel to that cylinder.



When you do the compression check you must pull all plugs out and disable the ignition and fuel injection. Also make sure you have battery fully charged.My car is giving me a headache any advice would help.?
well when you changed the plugs were they all a nice light brown color or were they black with abuild up did you have any that were white did any have a build up across from the tip to the electrode? i ask because this would be what you check to help determine problems if any with your engine also did you change the air filter compression test=compression tester =autozone, three squirts oil crank over about 4 times write down repeat for all cylinders all readings should be within 75%of each other next get long screwdriver put handle against ear other end against injector listen to see if all working good luckMy car is giving me a headache any advice would help.?
mostly could use a tuneup through a Nissan dealership
