I'm working with a 1994 4 cyl. 2.2L Camry. It suddenly started running rough. Like a bad miss. Replaced the plugs, wires, dist. cap and rotor change. There is fire going to the plugs...

it may be an injector problem on that cylinder, the injector could be blocked or the wiring or connector is faulty.....hope this helps......cheers.

I changed my front 3 spark plugs and a broken wire now and i have very bad rough idle and i could hear clicks? whats going on? should I put the old ones back on? the new ones were bought from...

The spark plugs should be matched up with the old ones to be sure that are the same as the new spark plugs and that the threads are not too long or too short and if the spark plugs were pre-gapped or if they need to be gapped, and the auto part store should have given you that information along with any spark plug gap because some spark plugs you can not set the gap on or they will be damaged. The spark plug gap should also be printed on the emission label out under the hood. Also, the other three spark plugs and wires should be changed to complete the ignition tune-up.

The spark plug gap should be the same amount between all of the spark plugs, and the farther apart that the gap is between the spark plugs the rougher the engine will run and idle, and the closer that you get to the same spark plug gap between the spark plugs the smoother the engine will run and idle.

It is also very important that the spark plugs be connected to the correct terminals on the coil pack or the engine will have a severe mis-fire and it will set a mis-fire DTC (Data Trouble Code) and cause the check engine light to come on.

Here is a firing order diagram to help assist you and let me know if need help with this diagram or if you require any further assistance.

How to check and fix a cylinder #1 firing problem. Cylinder, plug, or wiring?

You can test each spark plug, but disconnecting the wire as the engine is running. If it runs rougher, then that plug was good. If there's no change, then that plug may be bad. If it runs rougher, it could also mean the wire is bad.

To test the ignition coil (you may have one coil for each spark plug, or one for every two plugs, this part I am unsure of with your model) remove the wire from the plug and then remove the spark plug, then put the plug into the wire (DO THIS WITH THE CAR OFF). Start the car and while using INSULATED PLIERS touch the plug tip to a good ground spot such as the frame even the engine itself, but not to the battery. If there's a spark or crackling sound, then that coil is good.

You can test each wire by hooking it up to a voltmeter and setting the resistance to 20,000 OHM.
The reading will vary based on the length of wire. 12inch wire may register 6-7 while a 30inch wire may register 8-9. If it registers below 6 regardless of length, then the wire should be replaced.

1995 Alitma ran rough and stalled

Its just fouled some plugs again. Need an overhaul. If you just put a valve job on it it will just put more stress on the rings and will need it anyway. Not much you can do except change plugs all the time!
