Service engine light can come on for any number of reasons anything from a sensor failing, to running to rich or lean, or even a misfire

if its on there is something wrong

the best thing to do it to have a code reader put on it to find out what the code is for.

My 1998 citation developed some kind of fuel fault. Check engine light came on, this shortly after filling with fuel whilst engine running. Oil pres temp and volts remain good but shortly after that e


First, never gas up while the engine is running it's a fire hazard to you and everyone else at the station. Did you check air to fuel ratio? Is car getting enough of each? The check engine light came on at gas station because of the car running, just like a loose gas cap can trigger it.

Obd code p0457 fuel cap replaced mil reset defect not cleared connection checked ok


The code is for a large leak in the EVAP system such as a loose or missing gas cap. But it could also mean a loose or missing hose to the canister or other leak in the tank.
The computer vents the tank several times an hour while the engine is running, and it checks the system by pressurizing the gas tank. If the tank will not hold pressure the code is set.
You may have to check the top of the tank where the fuel pump gasket is, as well as the vent lines to the front of the car.
A mechanic would perform a smoke test to look for leaks.

Runs perfect allaround town back and forth every da .Get on freeway about one hour it shuts down no engine light notting .Next morning starts runs fine all over town.


your going to start with the crank sensor and go from there,when car dies you are going to have to check to see if your losing spark or fuel.remove a plug wire and place it near a good metal ground have someone spin engine see if it still has spark when it doesnt start, next is fuel top of engine find valve,almost looks like a tire valve, remove cap use a pen to push valve, hold and trun engine gas should spray, start there. hope this is helpful.

look closely at the cap to make sure the rubber seal isn't damaged, have the cap vacuum checked. if everything is ok with the cap, scan for what the check engine light code is. if it is a large evap system leak, the system may think the cap is off because it cannot build up any pressure in the system.

it starts from cold because the auto choke is on ,allowing a richer mixture ,try removing the sender unit in the tank and seeing if the connection from the pump to the outlet connection is ok or leaking causing a loss of fuel pressure

Check engine light comes on temporarily - engine chuggs at idle


Before changing you pcm try cleaning your egr valve. remove the valve and see if its stuck in the open position if so use a small pick to clean around the spring.
