Within the past few months my vehicle has started having problems starting. It takes several seconds to turn over, and sometimes once it has turned over, it idles rough while still parked. This usually isn't a problem when I start it for the first time of the day, but if I drive somewhere, park it to do something, then come back to it to start again it struggles more. If I notice it is struggling to start, I sometimes just turn it back off and try again and it usually has enough to turn over normally. It seems to be getting worse and I am afraid that at some point it will not start for me.
In addition, my vehicle has had a serious decline in its fuel economy. I used to get close to 400 miles to the tank (~13 gallons) and now sometimes I don't even get to 300. I was thinking it might be because I started driving more city miles, but even recently I went on a road trip, all highway and the most I got to the tank was 310 miles.
Within the last few months I have
-replaced the fuel pump
-new spark plugs
-regular oil changes
-new fuel filter
-tried several fuel injector cleaners including BG44K
Please help I have spent so much at the shop with wrong diagnoses. Thank you very much.
