Not much info to go on but a complete tune up might be in order.
Take it to Auto Zone and have the codes read for free.
Whats wrong when an 86 ford aerostar keeps trying to start after the engine is running?
I also have a similar problem. I cut the wrong wire while installing speakers with the truck battery running. Sparks shot out and now my windows wont roll up and my cab light comes on when I push the brakes. I have checked the fuses and the relay. ??
try changing the ballast resistor on the firewall, porceloin block with wires running to it.
sounds like a bad light switch.
Needs a tune up?
Your alternator is not keeping the battery charged.
need to check your evap system or you have a blown head
Sounds like the car is running off of battery power and the battery is very low on charge. The charging system has failed.
If it sputters under drivers seat only aT 30 mph or over, it may be not so much speed but wind related-chk for loose undercarrage flap, exhaust system or anything directly under car for loosness-especially exhaust shields.
take it to a garage there may be something wrong with the fuel delivery system.
could need a tune up---plugs, wires, fuel filter & air filter...good inexpensive way to start
Check for a Vacume leak, EGR valve
one of your problems could be in the injectors they maybe putting to much fuel.
Because it's in park.
for me it was a small rubber elbow that connected one of the vacuum hoses. It was a $2.00 part at Checker.
EGR valve, Fuel filter, Crankshaft positioning sensor. One of those, perhaps?
