The check gas cap light came on and two days later the service engine light came on so i replaced the gas cap with a new one and reset the service code to go off and the next day after driving about 25 miles the check gas cap light came back on the car is having some issues starting up
Take the vehicle to a qualified repair shop an have the EVAP system smoke tested , this will find the leak . Too many thing's that could cause your problem . You don't want to keep replacing parts do you ? Could be a stuck open purge solenoid , a leak in one of the vapor lines , the part the gas cap screws into, vent valve stuck open . Service engine light on ? have checked for DTC'S - diagnostic trouble codes . You'll probably fine a evap code for a large leak.

HI....
You don't have to worry about P0411. But you need to fix.
because the vehicle will burn more gas...
Let me Explain a little bit. of the SECONDARY AIR INJECTION SYSTEM.
Your vehicle use a Vaccum Electric pump. to reduce the HYDROCARBOM EMISSION , During a Cold start the System forces filtered fresh air into the exhaust stream in order to accelerate the catalystic operation.
The IAr is send to the exhaust passing from a check valve.
The code P 0411 , Can be a restriction on the hose coming from the Air pump to a Exhaust. or The hose damaged or pinched.
But the first step is check the operarion of the pump.
Check the Air pump relay. and fuse.
The pump Is located on Left Front Frame Rail, Forward of Fenderwell.
P1660. This code refer to a : Excessive Current or Voltage ON the system.
Check The ALTERNATOR for proper Voltage charging.
If the Alternator is charged more than 16v. replace the alternator.
Remember if you gave a Jump Cables of any time or day.
Any of this will the code P1660 come..
The ECM can BURN. For HIGH VOLTAGE, BE CAREFUL
After you check the Charging system. And detect that everything is in order, Clear the light.
PRINT THIS COMMENT and give to your mechanic....
I hope this will help on your problem.
THANK YOU FOR USE FIXYA>>

you need to put it on a computer to find what the code is such as on o2 sensor or a number of other things. once you know the codes you can fix the problem

Did u have engine codes scanned? If not, have it done, as it may indicate the problem. Let me know. (most parts stores will scan for codes free) .

Hello! There is a device called a purge valve; located in the back/right of the engine compartment next to the throttle body. The original fault was a "mass evap. leak code. Changing the gas cap was the correct, least expensive move. The purge valve is the likely culprit. If the catalytic converter was at fault a code indicating; Cat., or O2 sensors would have been set. If the valve can not open to purge the vapor pressure will give the faults you are seeing. Also if valve remains open auto will not run right anyway. Evaporator problems are unrelated to converter trouble. I suggest you replace the purge valve. There is also a vent valve located back by the gas tank; It is a part of this very complex system. Give that valve a good visual inspection (broken or worn wires/connectors or loose hose) before you purchase the purge valve.
