[QUOTE="cheeser, post: 16372971, member: 142342"] Unfortunately, the P219A issue still pops up every now and then, although the CEL doesn’t pop up. Odd as it could go 50 - 100 miles without a code, then it will just pop up the next day. It seems to run fine though. VMP advised me to replace the 02 sensor on the passenger side header. I purchased a new one, but was unable to get enough slack and get my hand in there in order to disconnect the electrical connector...I may have missed one of those plastic retainer clips. Tried for an hour twisting and turning with no luck. it’s aggravating, but at least all of the emission related test work now. The car is in storage, but will try again late spring. I purchased a few tools to unclip those retainers, and one of those remote endoscopy type cameras I can connect to my phone and snake it to the connector to give me a better view. Was thinking of using an unlit propane bottle to pass around the intake to see if the revs change that would indicate a leak. I am also thinking about having a local Mustang tuner w/dyno doing a tune...they have a good reputation in the area and deal with the Denver altitude. [/QUOTE]
