One of the headlamps burned out the other night. Went looking for a replacement and all I could find were these fancy extreme this or hi-vis that foo foo bulbs that all say they don't last as long as the originals. I wanted some plain old AC Delcos or Phillips 9008s, that's it. Amazon couldn't get the ACs to me in time so I cancelled the order which it seems they were happy to do. Cryptically somehow, I found plain old Phillip 9008s at Amazon too a couple days later and ordered up a pair. My daughter and I put them in the long way, loosening the bumper/grill and removing the screw in front of the wheels. Took about an hour.
Took the girls out for ice cream after dark and a CTS was flashing his hi-beams at me, no knuckle, these are just new! Turns out the bulbs had been replaced before and were Sylvanias. They never lasted in my other cars and the new ones are brighter it seems.
I've read from time to time fellas losing gas mileage and attributing it to a K&N air filter contaminating the MAF or restricting the air flow. Just for grins I purchased an original high capacity paper AC Delco filter and we put that in and cleaned the MAF again with the special CRC cleaner.
The instant gas mileage (running 93 octane) from 35 to 52 mph was always in the 20s and often the mid twenties. An hours worth of driving including an idling session while the girls ran into a shopping store and for the ice cream and the mileage crept up from 12 to 12.5. Then we took her back out for some data logging for another hour which included some WOT runs and it came up to 12.9 mpg when we pulled into the filling station. Put her back on E85 and drove home. The point here is that the mileage is better but by how much we do not know yet.
Bought the proper bits to fix that stabilizer bolt I broke, picked up some other tools so I can re-torque the intake and exhaust manifold bolts to spec and bought new AC Delco upstream O2 sensors. Picked up some other things but this is the week my daughters are going to become aunts and my wife and I grand-parents so things may have to wait. Maybe.
The Fuel Trims are all over the place. From zero to -13 to +3 short and long, left and right, I cannot make heads or tails of it. So we took a Snapshot last night with the Tech2 and video taped it and as soon as time allows on this, the Lord's Day, we'll get it posted to Youtube for y'all to look at and see if you see anything amiss. Also going to transfer that Snapshot to my laptop which has the software on it for viewing stuff from the Tech2.
