the 100% directionless thread

@Lo2w, I'm stealing that idea lol.
 
Hmm...ok, so yesterday, going to work, my check engine light was still on, but it was steady, no flashing/continued dinging at me. Same thing going to the mechanic shop.

They offered me two choices, one they just hook up the code reader, show me the codes and that's it, no charge....or I pay them $175 So they can diagnose and figure out the proper treatment...yeah I choose the first option lol.

Funny thing is that when I went to drive my truck across their parking lot the CEL was off and didn't come back on. They pull up the codes, there were 3: p0300 (Random Misfire Detected), p0339 (Crankshaft Position Sensor Intermittent) and p0335 (generic Crankshaft Position Sensor).

My Google-fu says a faulty Crankshaft Position Sensor can cause some misfiring (I think? I'm not exactly mechanically inclined lol) but it looks like a $20 part I should be able to swap out on my own (hopefully without wrecking anything lol) seems like a good place to start..

Oh yeah yesterday the CEL remained off and I needed to run some errands anyway so I did that, paid attention, the motor seemed to run just fine, no lights on etc...then halfway down the freeway into work this morning it lugged a little, almost stalled and the CEL came back on and was flashing/continued dinging at me again for the 5 or so minutes it took to get back into work....so maybe try swapping out that CPS sooner rather than later?
 
It really irritates me when I see people make silly anti-2A arguments. To paraphrase one I saw recently, "you can't defeat the military with its $600B annual budget with your AR-15." Yeah, maybe so, but I think I remember when 200,000 Afghans beat the Russians...just sayin'.

Along with a few American SAMs.

I love when people say military grade weapons....because the military uses only the highest of quality and lethality when it comes to guns and ammo....:rolleyes:
 
Realistically, as a soldier, I lived for the insurgent dumb enough to challenge us with an assault rifle. The terrifying ones are the guys with IEDs or little, quiet 22s plinking at you from windows or trees or whatnot and you not knowing who they are or where they are.

I suspect that your CPS is failing. Modern cars use sensors to tell the computer the position of the crankshaft because everything (and I mean everything) is timed from that. Older cars were mechanically timed so while it was easier to get a car tuned, it was also more difficult to get an engine to be efficient throughout the entire performance envelope. Computers allow this but they're dependent upon sensors. If the sensor is starting to put out bad data, then the engine isn't going to run well (if at all) because the computer doesn't know when to do what. You might want to look into a couple things: one is the sensor, two is the quality of the connector and wiring (bad wiring can cause similar problems even with a good sensor), and three is if you need the computer to do a "relearn" procedure if you actually do swap out the sensor. I owned a Saturn S-series and the ONE sensor that could make the car not work at all is the crank sensor. That car needed a "relearn" procedure so that the computer could learn to "read" the data from the new sensor.

Yep. And when the Vietnamese embarrassed us. And when the Iraqis kept us bogged down for years. We're still in Afghanistan too, right? And we've all read a bit about when some untrained, ragtag farmers only needed a couple years to kick the British Redcoats back across the Atlantic. Throughout history, untrained common folk have often been underestimated.

Personally, I think every anti-gun argument is irrational if not straight-up untrue, but I agree, this one is probably the worst.

yeah we just got done for the day, about to head to the store to pick up a new one.

Is that relearn thing a requirement? Like if I don't get that done it'll still throw codes and whatnot? Or only sometimes?

Relearning in most cars is just disconnecting the battery or jumping a couple pins in your obd2 port, then running the car afterwards so that the control unit gets the fueling algorithm right sooner rather than later. Its not required, but you'll have better startups after fixing the problem. After a reset, the codes are cleared and will stay cleared unless if there's still an issue.

When you have a failing sensor, the car's ECU is being fed information that makes it run suboptimally or just outright bog down. Resetting the ECU by disconnecting the battery will clear whatever settings were built up by the bad information. Then the ECU will start optimizing using whatever information it gets afterward.

Check a manual or online if the car needs a specific relearning process, some cars need to be run at a certain RPM for however much time after you reset the ECU.
 
Ok, so I got the new sensor (turns out it was $35 not 20, but oh well lol), got it installed seemingly just fine. Hardest part was removing the old one, but I got them swapped with a minimum of cursing haha.

I had the battery completely disconnected, and when I got everything re hooked up and running again, the CEL had disappeared, yay! Seemed to be running just fine, nice and smooth.

On the way home, as I was pulling into my buildings parking garage, it stalled out suddenly, no warning, just as if you turned the key, no lugging or wierd noises, just "hey, why can't I stear?? Oh, the motor turned off...." Can't imagine that's good? The CEL stayed off tho.
 
Ok...so I replaced the Crankshaft Position Sensor with one from AutoZone yesterday.....and my rough idling/stalling out at stops has gotten worse! It went from an occasional, once in a while problem, to it happen like 5 times on my way into work this morning! (Not even throwing any check engine light!)
 
Woke up late and didn't make it to the gym. Lost my wallet somehow when I was getting ready to come to work. Have a migraine already...If anyone needs me, I'll be in my blanket fort.

Going to be like that, eh?
