Trying to figure out what is most likely the cause of the following symptoms to get wife's car running reliably again. It's a 95 model with 3.1 liter v6.
1 - MOST days, it runs perfectly without a problem whatsoever.
2 - OTHER days it may miss or "bump" at any speed intermittently while driving.
3 - TWICE it has just up and died on her while sitting at a stop sign, won't crank right back up but if it sits a few minutes it will crank up and may run fine for a few days.
4 - TODAY she says she was doing 15-20 mph in a subdivision and it started "chugging" and when she gassed it, it went on until she was back up to highway speed and it "bumped" again a few times but made it home.
I'm leaning towards the crank sensor(s) because I am not getting any codes to pop up BUT when I look up crank sensor for this car it shows one to be behind the main crank pulley and one on the rear of the engine below center of exhaust header. From what I can see BOTH of them will be a pain in the rear to change to say the least so that is why I am asking if something else can cause this before I go through all the trouble to change them, OR is one more likely to fail than the other and should be changed first?
