Does that motor have individual coils on the plugs ? ]

yes

Yes.

Then to the OP: Change the pulgs, when that doesn't fix it, start checking the individual coils.

Not necessarily. If the coil is intermittent, the car will run rougher when you pull the leads to that coil since it is firing _some_ of the time. Reverse logic is needed to find it.

Try this test: pull one coil. You'll notice that the car runs rougher. Listen to see if the original miss is there along with the new miss i.e. it will probably be running extremely rough since you have two misses - the original and the (now disconnected) pulled coil. Put that coil back and try the next, and so on. If it is a coil problem, there is one that you will pull that will not cause the car to run quite as rough since by removing it you will only have one miss, not two. Test several times and you should be able to find the coil that is causing the problem - if it's a coil.

Don't keep them out for too long since you are dumping raw gas through the engine... also, I have no idea what this does to the control module. I've tested this way before and found bad coils but I can't say that it's a good idea :-) You should have the engine good an hot before testing.

How many miles on this car ?

Thanks, I'll give this a try.

The car has about 70,000 miles > >
