Hard Start, Occasional Stall, Emotional Support
Friday evening noticed the car took a little longer to fire up on our way out to dinner, and then took 3 tries in the parking garage after dinner. Threw some Techron in it Saturday morning and I personally haven't had a problem since. However, my son has driven the car twice since then and said it stalled once on each trip on him (two different days - but both after idling at a red light). Car seems to run as normal, no check engine light. My son said it fired right up after each stall and ran fine after.
The only thing I can think of is that I let the fuel tank run very low (basically on 'E') last week before all this started happening and then filled up with a no-name brand (but premium grade) gasoline. Could I have run too low and had lower-quality gas cause these issues? I have a fuel filter on order - the current one is a little less than 4 years old and about 35k miles.
Just wondering if there is anything else I should think about. Mental check list - I don't believe I have put a battery in it in my 4 years, but doubting that would cause these intermittent symptoms (drove it about 20 minutes last evening to run an errand and it started up and ran absolutely perfectly). MAF or other sensors? I have SDS but would that show anything considering no codes have been set?
appreciate in advance.
