Well Lolas starting to run rough after 200 miles of highway driving its been about a year since my last tune up when we first got the car running its just a bit rough at idle and when accelerating at low speeds its getting an ac recharge on monday already though. anys suggestions? most passengers wouldnt notice it unless the looked at the rpm gauge

 

How many miles has it been since the last plug/wire change? If you used platinums or irridium plugs, those should go for almost 100,000 miles (I think some say 150,000, but I'm skeptic on that). If you used copper plugs, could be sooner (50,000-70,000). If you used BOSCH plugs, coulda been the same day you put them in.... lol

Seriously, how many miles are on the plugs and wires (and if you say that you did use BOSCH plugs, my experience has been they are lucky to go 6 months without mis-firing).

 

welll my dads mechanic checked them recently and said they were fine but that was 2 months ago well the car has 159k on it ive never changed them but they were in it when the car sat for years

 

If you don't know the mileage or types of plugs installed, it may not be a bad idea to change plugs and wires. They are pretty inexpensive. I recommend AC Delco's, but I've used NGK on one car so far and I've been happy (heck the original Delco's on that car ALSO read NGK, so they were re-branded). But do NOT use BOSCH plugs, they SUCK.
