I need some help guys.. I bought this standard cab 2wd truck for a winter truck so I can save my nice one. 

I have replaced the crank position sensor, had it relearned by my mechanic(trusted), new dist. Rotor, new plugs, wires, new coil, new gas cap, new fuel tank pressure sensor, no engine light. 

 

I can drive fine and then it will randomly miss or stall completely so I have to downshift and drop the clutch to restart it(bump start)

I was told it could now be either a bad ground or some sort of electrical issue. Could really use some advice plz.

 

2005 chevy silverado 1500 2dr 2wd 4.3l v6 manual transmission.  260k miles

Try your ignition control module if you haven't already figured this out. You can take it off, very easy its right next to the Coil. Take it to parts store they can test it. If it's not that. Buy a fuel pressure guage at harbor freight (best deal). These motors are very picky on fuel pressure, resting pressure key on engine off. And running pressure. Lots of guides online in s10 forums on how to check. Neither of the things I listed would throw an engine code that I know of. Sounds like you need a better mechanic. A good technician will diagnose a problem and know for sure what part is at fault before replacing any parts. Older mechanics go off of gut feeling and experience and throws parts at it till something works. Good for them because they make money but it costs you a fortune for a 100 part.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
