bad mpg

[crzybmxrdude]

A few weeks ago my g/f's 89 lebaron coupe w/ 2.5 TBI started running like crap, not to mention it was getting roughly half the gas mileage it got before (15 compared to 29). So I changed the distributor cap and rotor, the plug wires, spark plugs, and fuel filter. The car runs so much better now, but its now getting about 16.5-17 mpg. Any ideas???

O2 sensor

get a mopar one only!

check the oxygen sensor ground at the left side of the cylinder head, they tend to break off and will cause poor fuel economy.

Ok thanks guys, you rule! Ill check out the ground first and if I get nothing, ill do the o2
