Then check engine light came on and it was code p0455(evap control system gross leak detected) has anyone had this issue i had the gas cap replaced so i know its not that, what causes the slow acceleration.
Millions of cars have that issue
The Evap System, will most easily be diagnosed &
your Gross Leak resolved,if you have a repair shop
with an EVAP Smoke Machine put on that system
The Gas Cap would be a PO442 (small leak) The way you
remember is, from the Hurst Olds 442, from the 1960's
The smoke test will blow some out the place of the leak,
like a rotted hose or broken evap valve.
Slow Acceleration---you work on after all check light issues
are resolved such as the evap leak.

Okay, the code you got must be po455, the evap system is a system that is sealed or open and its for the fuel tank vapors, the computer controls it and if the computer closes the vent valve to seal the system and doesnt see the system build vac or pressure it turns on the light, this system takes the fumes from the tank and filters in through a carcoal canister and then it reburns it or releases it into the air after its filtered, this system is to help the ozone . you will not notice any diffrent driving just the light to tell you there a problem, a gross leak just means its looses vac fast, the most common reason for this may be the gas cap is loose or off, check the gas cap first, if its loose then tighten it and you will need to drive about 100miles depending on the type of driving you do, this will reset the light, if the cap is on and is tight then you may have a bad vent valve or a broken vacuum hose, this is not dangerous and wont leave you stuck on the road but i would have it checked to see what the problem is, this is only if its not the gas cap, heres a diagram to help you under stand it better, hope this is helpful have a good day.
SOURCE: engine light is on and code is for emissions leak evap sys.
One of the common problem with 98 Frontier is crack exhaust manifold, take the heat shield off the exhaust manifold and check it for crack.

make sure the gas cap is tightly sealed. Inspect the gasket on the gas cap

have the gas cap tested or just replace it, then disconnect the battery for 5 minutes to reset the code, then drive it for a few miles and see if problem comes back, if it does a trip to the dealer is in order, as this may be covered by your emission warranty which is good for 70,000 miles.

I just had the same issue with the same mileage as yours. Mine is the sending/sensing unit and it causes the range, distance to empty, etc. to be incorrect. The dealer is replacing for just under...$500. Another problem has been a whining sound under the hood, which they diagnosed as worn timing chain guides...cost to replace the guides is about $1,400. Not replacing results in the chain running on metal and chain wear, not to mention that whine. The service advisor said these two issues are the most common problems with Pathfinders. Good luck with your problems.
What does this mean? Tech notes What does this mean? When is the code detected?
