ok, well here is the thing, when my car is in neutral and I rev up the engine, the car will make that sound like it is missing...... and if I rev it and hold it to 2 grand it will hold then drop off and go back up..... So I decided to replace the boots and the wires.... still does it has new spark plugs... no check engine light.... what is going on with this car

 

what are your new spark plugs gapped at?

 

err they are iridium's

 

what are they gapped at? still need to check the gap to make sure they are correct

 

they are at 28.
