Question about 1996 Plymouth Neon
Check engine code was system lean bank 1
there were 4 possible problems.
misfire on cyl one
o2 sensor faulty
mass air flow sensor (only if system codes were the same on bank one and two, my car only has one bank. its a four cyl) I ruled this one out.
I changed the o2 sensor, check engine light still on.
still get 120 miles to a tank of gas
still shudders/hesitates between 40-50 miles per hour.
scratching my head....
It sounds like you have a fuel issue. you should check for proper fuel pressure. its should be 48 PSI.
if its not, it could be a clogged fuel filter, a malfunctioning fuel pressure regulator, clogged fuel pump strainer, or even a bent, kinked fuel line.
if the fuel pressure is correct, its most likely a faulty fuel injector.
by the way, you car doesn't have a mass airflow sensor, it has a MAP sensor
