    The car wasn’t driven that much last winter. But I’ve probably put around 2000 miles since last october. I was going to drive this car A LOT including commuting to and from work but my office just moved and it doubled my commute to 50 miles each way. Kinda iffy to drive the car in it’s condition that far [emoji23][emoji23].

    I’m planning to drive it more after the radiator is changed. Really enjoying my DD car though.

    Hello hello, figured I’d give some updates.

    I’m just going to upload some random images with a description lol!

    The bent TB:

    Freshly rebuilt by KW. I’m excited to install these babies:

    Cracked FP gauge. Don’t worry, replacement is otw.

    Picked this up from @KingScumbag

    In the process of replacing the radiator, I went ahead and took out the White Widow IM gasket I’ve had on and replaced it with OEM. I heard those types of gasket don’t play well with JMF and I did it just as a preventive maintenance lol. Also replaced my TB gasket with one from AP (donated by @SharksInSpace;, thank you sir)

    I wanted a way to monitor my inline pump.
    So @JohnnyTightlips; had an idea. We searched on RockAuto and bought this fuel pressure sender. The idea is for an LED light to light up in the cabin to notify me that the pump indeed runs. Unfortunately, this idea didn’t work as we thought. During testing, the LED light wouldn’t light up even when there was pressure going through the line. But hey, it was worth a shot.

    So after the radiator was in, my fuel trims started going wonky. The first thing that came to mind was boost leak. So my buddy and I met up last night at the shop he works in and he helped me tremendously. We found a couple intercooler couplers and my BOV fitting to be leaking air. We cleaned the MAF sensor and found that the o-ring was fubar’d. He improvised and replaced the o-ring with some random one he had at the shop.

    Upon starting the car, I was greeted with worse LTFT and STFT than when I began with lol. I tried swapping the MAF with a known good one and it didn’t change a thing. At this point it was already 8PM and we called it a night.

    Anyway this morning @Maisonvi; advised me to reflash the tune. Now I just have to drive the car more to see if fuel trims would settle for the better.

    Stay tuned for more KiwiFail!

    Your o-ring on the MAF is 100% right? Not nicked or anything? Just throwing it out there.

    The replacement o-ring looked good when I swapped out mine with my buddy’s MAF and we knew his was good. I will be getting an o-ring from Ken the man hopefully soon.

    Btw after reflashing the tune this morning, I took the car out for a ride and it seems that fuel trims stabilized. It fluctuates to 11-15 sometimes for a split second part throttle but stays within 7 to 9 and -7 at the lowest. I will keep an eye out for the next couple of days.

    Idk if swapping from a cs to oem throttle body will fuck with fuel trims.... but my guess is yes.

    Never really thought about that. But that's 100% a possibility. I have yet to grab logs.

    Bump!

    Been driving the car a lot this past week and it seems that fuel trims stabilized. For the most part they stay between -7/ +6. Occasionally it spikes to -12/+14 but it only happens for a split second. Not too worried about it.

    I'm also running out of E so I've been kinda taking it easy on the pulls.

    I actually put the car up for sale about a week ago but there doesn't seem to be enough interest. If it doesn't sell, I'll just keep it and clean up the odds and ends bit by bit and maybe get it repainted. The registration also expired as of today. Looks like the car is going to be parked for a bit.
