April 13, 200520 yr my 98 legacy gt is idling a little rough even when warm.. i replaced teh pcv valve like 300 miles ago.. i cleaned the TB.... i havent replaced the eplugs yet.. the car has 60k on it... it just feels like the car is loping... i use shell 93 octane gas.. i seafoamed it through the brake booster once.. any suggestions to check on?
April 13, 200520 yr 60k miles? Time to consider replacing the fuel filter, spark plugs, and depending on engine: The timing belt!
April 15, 200520 yr Author car had major work for the headgasket. during this.. i replaced the fuel filter, they checked the timing belt so it was like new.. i need to replace the plugs... im sure they are the originals.. whoever owned this car before me (curse them for their lack of conscience and selling this car) were not quite as obsessive as i am.. fuel filter was clean .. 60k miles? Time to consider replacing the fuel filter, spark plugs, and depending on engine: The timing belt!
