  1. Safe mode P0171, P0300

    So wasn't the intercooler. One of the throttle body hose clamps was busted but didn't look busted. Replaced it and was still getting the same issue with but slightly less worse. Stability control light came on so decided to thoroughly go over the brake booster line and it has a leak in the...
  2. Safe mode P0171, P0300

    New harness is installed and made a huge difference. Still throwing a pending lean code. Took a short drive and it ran great until safe mode which took much longer to trigger and went away faster. Did a boost leak test and no obvious leaks but I think my intercooler may have a slight leak on...

    Not the best with wiring but I pulled two pins and the wire that I thought is the issue is definitely a problem (may not be the final solution but definitely needs attention). Ordered a pig tail from Amazon. Easier for me to solder it in vs. fighting with the pins. And for anyone else that...

    Had a buddy come by for a second set of eyes/ears and while he was here I double checked the MAF harness. It finally did affect it when moving the wires around. It's now throwing the two MAF codes. It looks like it is the middle wire. Can I pull the wires and rewire it or should I just buy...

    Well have to build a tester so will probably be a couple days before I can test it.
  6. Safe mode P0171, P0300

    Just cleaned it again (had done it before) and no difference. Wires in MAF harness look good. Intact and seated. Stft still stuck at 25 during idle. If you give it gas, it drops like it should. If I very slowly increase RPMs, it will drop to zero around 3700 and then trigger safe mode. When...

    Did this and it didn't seem to make any difference. Wires look ok as well. I'll look it over with some daylight and toy with it some more tomorrow.
  8. Safe mode P0171, P0300

    And for other common questions. Yes, plugs are gapped properly. Bought a new coil pack and rotated them to make sure it wasn't a bad pack and/or gaps causing the misfure. Parts cannon has been sequential as I have gone down the most common causes. I don't have an access port but a decent...

    Ltft are at 0. Stft drops to zero like it should on throttle but when it goes to idle it stumbles and sticks at 25. After stumbling it idles smoothly for the most part with a slught hiccup on occasion. P0301 is misfire cylinder 1 and P0171 is bank 1 too lean.
