Car is missing in both high and low rpm's changed fuel filter and stopped missing for a while then started up agian. have already swapped spark plugs, distributor & rotor and spark plug wire as well. was wondering if fuel pump would be the cause of the problem? My car is a '97 nissan 200sx model se 1.6 liter with just over 200k

get it serviced?
hard starts are usually never getting a tuneup, (like spark plugs?)
slamming in to gear is normal if RPM is too high in park, is it.
wont move , in any gear, car wont move even in reverse.
and RPM of engine does what , sticks low, like 800 rpm
or screams at the advancement of right foot.
need lots of details. we cant drive car, but if could in 5min flat all that is clear,
eg:
transmission slips
engine weak
engine racing in park too high.
wont start and misfires when it does.
is fuel fresh, not year old.
ever get a new air filter and fuel filter. if filter is outside tank.

-----------------

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

This will help.

Thanks.

May have a vacuum leak or. Fuel issue. Check fuel pressure it may be low. Means pump is bad and change fuel filter at same time if it's clogged replace

try replacing fuel filter

good day Sir, try to check the spark plugs and air filter i hope this will help

Does that mean it does not stall or **** in 3rd gear?
The difference between low RPM and high RPM is primarily a greater fuel requirement. So a fuel related problem like clogged filter or bad fuel pump or return pressure regulator comes to mind.
Spark is also slightly RPM related, so you could have the ignition control module checked at Autozone or a place like that.
Other RPM related items, such as EGR, PVC, and tank purge valve are not likely to be so dramatic alone.

Hello! A cylinder misfire can be something as trivial as needing new spark plug wires, to having a dangerous lean condition in the fuel mixture. Assuming that you have a stock, un-modified car, with a stock, un-modified PCM, my suggestion would be to swap the coil packs, to isolate whether or not the 1 - 4 coil pack is faulty.


Hope this helps, and thanks for using FixYa!

Swap the coil pack to another cylinder if it is individual. If not, you should be able to pull the wire away from the plug and hear it fire. If not, you have a bad coil. If so, I would look at doing a compression test and possibly a leak down test.

change plug and wire if its been a while most cars have 90000 miles platinum plugs in them.but the wires wear before plugs.so change plugs and wires.+clean fuel injectors .change fuel filter and air filter.if car still run rough your idling to low.have idling check .

Pin point the dead hole and check that injector.
