Hi Luis,

There are no dumb questions.....unless they're asked by me!

It is my understanding about SES lights or codes in general that once a DTC is set the light goes on. However a key cycle in an OBDI car will erase the code if it is not present on the next key cycle and send that former DTC to the CCM as a "H" History DTC....that is called a soft code vs a hard code like when something actually breaks. Usually our cars set soft codes if a system like the FX3 or the ABS doesn't get enough time to do a self test. I used to get soft Cam sensor codes in my car all the time until I used a different starting procedure. Okay enough about stuff that I really don't know....'puters! I stink at 'puters!

Okay new coils and the wires Ohmed out okay, but when a wire is actually on a running motor it vibrates and if the carbon core has cracks in it you would never find them if it was laying on the bench with the VOM attached to it. It's kind of like looking for the break in the vacuum cleaner cord. With what you just told me I have a bit of prejudice toward that wire @ #4 or that tower on that coil. Okay that plug could be no good right out of the box also.

The reason I suggested that checker is that it works well for the price, and remember never pull a wire with the motor running on our ignition system! That's bad for the DIS box.
