why does my sons 1995 Lincoln sound rough..the engine light is on..he just informed me no tune up in 2 yrs?

Question

Serious answers only please. It runs good except for the rough ideling (not too rough) but he notices the diffrence. Does it need new plugs?? Please help shed some light on this for us. Thank you.

Answer 1

tune up is a start , yes plugs also fuel filters air filter , oil filter and oil , that's all for a start ,may be wires to, you must keep it up or it will let you down in time

Answer 2

plugs and wires are in order. other things to check and posibbly change fuel filter and air filter ,o2 sensor this is a start . do the plugs and wires first because it can affect the o2 sensor which may be keeping the check engine light on i tell people to do the simple and cheapest first. and all this can be done yourself with hand tools and a little time if the light stays on after you have changed the air and fuel filter and the plugs and wires . and driven it 10 to 15 miles then its time to check the sensors codes again . alot of people think that disconnecting the battery will clear the codes and it will but you also lose data at the sametime driving on the other hand will do the samething if the problem was solved by the forementioned tuneup . if not you have not lost data that would be helpful to a service tech. hope this helps

Answer 3

The "Check Engine" light being on tells you something is wrong. One of the emissions sensors has failed and the computer is trying to compensate for the missing data. That's why the car is running badly.

Get the fault codes read then repair the problem...Soon!
With gas over $3 an engine light is costing you BIG time!
