I have been sorting thru posts and replies in this forum for over 3 hrs now and cannot seem to find anything on this trouble code

P0301

I know it can be one of the following things:

Ignition System Fault ( already changed the plugs and wires )
Vacuum leak (checked, nothing found)
Fuel Injector Fault (any help on how to check this)
High or Low Fuel Pressure (trying to avoid going there)

Vehicle: 2000 Hyundai Elantra 2.0 Manual Trans. 130,000 miles

Any help would be great

 

Hi Member:
The code you put in there can be caused by multiple cylinder misfireing from cylinder #1...Check for faulty spark plugs, wires and coil, also check for vacume leaks and even fuel injector problem...have a fuel pressure check done by someone who knows what theyre doing..Hop this Helps you out:

If you had a bad injector, your car would be running very poorly.
When was the last fuel filter change?
Fuel pressure drops are 9/10 a clogged filter or the fuelpump failing.

 

po301 - is missfire #1 cycliinder most likely on a elantra its plug wire - or plug /coil

 

I would say most likely is a coil pack problem.

 

What he said--- wire, most likely.
