Hi my name is Robert...

IS the check engine light coming on and when was the last time you had the chassis serviced?


Expert:  Robert replied 7 months ago.

You are allowed to follow up as much as needed.

IF this is happening after 20-30 miles I would check your coolant and oil levels, make sure the coolant level is not dropping down when the engine is warmed up. I would also take a voltage reading at the battery you should have 12.5 volts at idle, want to make sure the voltage is not causing the engine to cut out, if the voltage was low due to a loose belt, bad battery or bad connection it could cause problems. Finally I would replace the fuel filters, make sure you do not have one that is partially plugged up, if the engine light is coming on then I would have a shop hook up to the engine computer and have codes pulled, in the long run having the codes pulled takes out most of the guess work and in the long run saves time and money... I would check the simple items first and then see about getting codes pulled... Hope this helps some, IF you have more questions or concerns please feel free to contact me..
