Just got a 1996 Stratus with 2.4 engine; 95,000 miles.
Problem: occasional rough idle, rough acceleration--like the engine cuts
out. Won't go above 45 mph without cutting out, often accompanied with a
noticeable "muffled" backfire sound. Generally weak acceleration, but at
other times the engine purrs like a kitten. Car sat idle for a year but has
new oil and filter, air filter, etc. Haven't checked plugs yet. Put can of
fuel injector cleaner in but no improvement.
The car was given to me and I have no experience with the make/model and I
don't have any maintenance records.
Can some suggest a place or system (fuel, electrical, emissions, etc) to
start tracking down the problem(s)?
