were the actual code numbers P0303 and P0304..


your coils look similar to these..

did you have any trouble fully installing the spark plugs.  i have seen way too many spark plugs cross threaded and not fully installed..

this puts the spark event from the tip way up in the threaded hole not out where it should be..

pulling the coils.. sticking a ruler or something down the spark plug hole to measure from the top tip of the spark plug to the top of the tube it drops into.. this is not a precise measurement.. you are judging if any are about a half inch higher than the others.  indicating a screw up..

if you find this condition. there are ways to fix it.. don't try to tighten the spark plugs to get them fully installed.


ignition coils if you look at the image.  need a tiny amount of spark plug boot lube or dielectric grease wiped around the inside end of the boot.. but not up into the metal contacts..

do you have any vacuum leaks.  where the injectors were not properly seated..

where vacuum hoses got left off.. or gaskets were not replaced..

or intake manifolds where not evenly tightened.

did you put the dielectric tune up grease inside the boots to seal the spark from leaking out down the sides of the spark plug insulator..

which codes.

do you have a scan tool that displays live data and also graphs the oxygen sensor data.
