My significant other bogged my Yukon down to just below the frame, of course to get it that far down he was revving the engine pretty hard. Once we got it out it has been in reduced power mode ever since. Along with all these wonderful codes: p0113, p0118, p0358, p0361, p0442, p0443, p0448, p0449, p1516 and p2135. Before the bog down, we’ve put a new battery on it, new throttle position sensor trying to fix an issue where pressing the accelerator was like hitting the brakes, the more you tried to accelerate, especially from a stop, the more it became another brake! To stop that issue so I could get home after work a friend of ours pulled a fuse disabling stabilitrack, I’m pretty sure that’s the fuse he pulled. Anyway, my truck ran like brand new until it was bogged down. Now it blows blue smoke, idles so bad, it’s in limp mode. 35mph is what it’ll do 40 if I’m going downhill and gotta beg it to go up the next. Where do I start with these codes…. And another question my OBD2 code reader, code p0358 says ignition coil h and code p0361 says ignition coil k, but nowhere can I find anything about them being called by letter, it’s by number…..wtf??? Thank y’all in advance for any help guidance you can offer, I’m way in over my head but I’ve had a few try to rip me off so I’ve learned I can work on it myself with a little patience and guidance! And what a thrill to fix it too!!!
