Direct wired my Uniden R3 Radar Detector to the back of the mirror, way too easy. The mirror mount/wiring came with two additional "round " wire extensions that fit into the brown/yellow hot and blue ground at the back of the mirror.

I mean I’m leaving my full suspension etc.

My concern is randomly my afr goes everywhere.

Ie. Cruising 60mph cruise control flat land

Goes from steady 14afr to 12-15-12-16-12-15-12-16 for like 5-10 seconds

I cannot recall it happening before the downpipe

Once I removed downpipe I still had it, so chef sent me a used o2 sensor, mine vs his.

My logic is if the o2 sensor was this dirty maybe a new set of plugs would benefit. I just pulled plugs and they look fine I thinks but I am tossing new ones in anyway since already got them out

What’s with the white stuff on bottom or coil packs? Normal?


Edit just checked all 4 plugs gap, exact same gap as the 0.028 I gapped them too originally. So they held up to the increased boost from downpipe like a charm


This little gadget from China and feeler guage works great!

White residue is usually not a good thing, indicative of corrosion or carbon tracking. Did any of the ceramic portions of the plug have a strange line etched into them? If the car is running fine I wouldn't worry about it, but a good clean and some dielectric grease on the inside of the coil boot wouldn't be a bad idea.

Hey guys; I had my car on a lift to do downpipe awhile back, I did an oil change beforehand and when it was on lift I noticed oil beaded up on oil filter

I thought it was maybe leaking, so I removed filter, inspected gasket and put it back on. I lost some oil. Not sure how much

So everyday I’ve been adding like a little bit of oil. I was adding to fill to the top of hash marks completely cold.

So everyday I have inspected, this is a 4th of quart added over a week.

I have a hard time feeling like I lost half a quart of oil.

When I did oil change I did exactly 5.7 quarts (17 ecoboost)

Is the top of hash supposed to be touching or am I supposed to be in middle of the hash area cold?


The manual just says, if it’s below the bottom hole add lol.
Should I leave it as is?

I’ve never removed an oil filter before before an change. I don’t think it was leaking, I think it was just residual oil from previous change on bottom of filter.

We took a road trip today... Buffalo, NY, a five hour drive. Camping out by the airport, was a beautiful day for a ride other than the relentless wind!
