2001 Dodge Neon

Asked by Jan 17, 2017 at 01:11 AM about the 2001 Dodge Neon 4 dr Highline SE

Question type: Maintenance & Repair

I have a very basic understanding of the
combustion engine, bit I cannot figure out what is
wrong with my car. While idling at a stop light  the
engine was sputtering a bit, no backfire or
anything, but when I gave it gas it bogged down
and it would move in any gear. I checked the air
filter, that's fine. I guessed that maybe moisture got
into the fuel line and froze since the high temp for
the last week was 12 degrees. I added a bottle of
Heet, but it isn't even turning over anymore. I
haven't replaced plugs or wires in a little over a
year, but it had gone years without needing new
plugs or wires so just over a year seems too short.
I've never replaced the coil. I have been getting
terrible gas mileage for 2-3 years, progressively
worsening, and I ran out of gas on the 5th, but I
have filled it twice since then and not let it get
below 1/4 of a tank. Any suggestions would be
appreciated because as a single mother/student...
I cannot afford a new car or a mechanic.

Bad gas mileage is usually and indication of a clooged converter ir O2 sensor. You may want to check the fuel pressure at the rail with a gauge it should be between 35 and 45 PSI with ignition in the on position. If that's ok then start the car if you get low pressure reading in the 20's while giving it gas it could the fuel regulator....
