So i was picking up a friend from work and turned my car off. it was running fine. i start the car and it feels like its chugging and the service engine soon light was flashing and is solid now. What should i check any ideas on what is wrong? after the problem i shut the car off than started it again and it ran better again... idk what to do?
first thing is to read the code, most auto parts stores will do it for free. hard to guess with such little info, could be anything from the air intake (like filter, MAF, throttle body...) to fuel pressure (injectors, fuel pump...) to the exhaust (o2 sensors, cat...) and just about anything in between...
get the code and write it down and have them erase it if they will... can use this link to research whatever code you have.
Code was P0300 Random engine misfire. cleared the code and car is running fine if it happens again off to the shop. In california auto part stores cant read codes by law
when I had a misfire in cylinder 1 it turned out to be the spark plug. hopefully it'll be something cheap like that for you.
BTW- didn't know that about CA... what a PITA it is to own a car there... you most likely still have the faulty pre-cat sitting next to your block like a time bomb... hopefully that's not the issue, but if you start going through a junk load of oil then you'll know your engine is about fried...

Pre cat? thats been gutted to pass visual and if it was already bad when i bought the car can we bore the cylinders out or no?
sorry, I've only heard that the engine is trashed if it has gotten to the point of damage due to the pre-cat. doesn't mean that this is your problem with the misfire. I would keep an eye on your oil, but most likely it has something to do with the spark plugs, gas, or even your injectors or fuel pump. I would look at those areas before thinking it's major engine trouble.
I think it could, the knock sensor will modify the timing if it senses the engine knocking. it says in the handbook that came with the sentra that you should use a certain octane rating (forget what it exactly is) but premium is the only gas I can use in Ga that is equal to or better than the suggested rating. have heard of guys running regular, but not sure what long-term effects it has on their engines...
I'd suggest changing the plugs and using premium gas to see if that clears it up, if you've used regular for a while, you should notice the little extra pickup w/ clean plugs and premium fuel.

i know thread from the dead but all my spark plugs were more than 1mm off gap so hopefully that isnt the problem thanks for that idea

what kind of plugs were they? they should have came with correct gap, maybe someone put plugs in for the 1.8L sentra... stock should be NGK PLFR5A-11, and I've been using the E3 plugs for 3 months with no prob, forget their # though.
nice, hopefully those will do you right. according to nissan, you should never have to gap them and if the are dirty, it's better to replace than to clean them... not sure why, that's just what nissan says.
