    Probably lack of maintenance honestly, as long as it runs i really don't care, looking at a rebuilt engine for under $2500 and do a 383 convert to the original. If it works and happens again ill straight pipe it and put o2 back in it to pass emissions at this point. I burned up my grinder and my...

    Also old plugs came out looking like crap, smelled like gas, probably due to the catalyst code and faulty o2 sensors, covered in soot after 2 months

    Sorry, no lights flashing, body control module and passenger restraint system as it has no airbags upon my purchase. Before that was knock sensor 2, (rear valley), they never sealed it so antifreeze leaked into the valley, changed both twice with new harness and get proper volts from main...

    It did indeed just happen after i drive it 40 miles to my other property I'm selling. It literally just died, no knock, no bang, turns over fine, but when it catches it idles for a bit fine as soon as i tap the pedal it sounds like crap, as described above, engine knocks around a bit, which is...

    All coils plugs wires battery all new say after purchase, all the way to differential fluid, i gotta drain the coolant anyway, i didn't have any pending codes when i tried it, didn't have enough miles to register memory either before it took a crap. I do have translucent dye on dipstick, so I'll...

    Thanks for replying, attempted to change the filter the day after i bought it, right and i got lazy but i checked the Schrader valve already and spray is still amazing. But that deep hollow sound on the passenger side engine is scary to say the least engine turns over no problem and plenty of...

    Update: once again I've never had this issue with any vehicle that I've ever had in my life.
