YES!
Engine that was operated with a loose , missing or bad fuel cap.
Yes, this is often the reason why the check engine light comes on.
96+ vehicles missing the fuel cap will activate the check engine light and set an evap system gross leak code. If your temporary cap seals properly and is correct for the application there should not be a problem.
if engine runs fine but computer has [large] emissions leak , check too see if gas cap is on all the way or missing,
No. However, some cars will display a "check engine" light on the instrument panel if the gas cap is loose or missing.
no srry
The check engine light indicates a problem with you engine that may or may not affect the way it runs, the only way to tell is to have the codes read at the dealer or a parts store that will do it for free and use the information gained to affect a repair.
Depending on what year Jeep you have, it may cause the check engine light to come on. It won't effect how the engine runs but it will effect the emissions.
It could be that you have not tightened the cap on your gas tank. Be sure to check the gas cap and see if its being properly tightened. That was the case for me a couple of times.
get under hood and rev your motor manually.......till you hit around 2000 rpms than while keeping motor reved adjust the cap....now if you are too advanced on your cap youll hear a popping missing noise.....back off the cap counter clockwise till the engine runs smooth....if you retard the cap too much the engine will run with a hesitation....that's the closest youll get other wise youll nweed to hook it up to the computer at the Nissan dealer and theyll chargre the hell out of you ***See what engine code you have. If it is a Maxima SE (DOHC)(VE30DE engine code) you will have a timing chain instead of belt and probably no distributor. The GXE (SOHC) has the VG30 engine which has the belt...
make sure gas cap is on all the way or missing cap ,this car must have a gas cap or computer will read [large] emissions leak or emission gas cap, hope this works!
Cracked distributor cap or bad spark plug wires/connections.
