I need some help with my 2000 LS V8 3.9L. I never had a big problem with my car yet luckly!(only thing was replacing the coils), until now. My car now has 95,000 miles on it and my engine is acting up. It has a rough idle and when accelerating it goes up and down while speeding up. I had a code of P0171 (bank 1). I found oil in my spark plug well driver side. I replace valve cover gasket and replaced all spark plugs and coils (No more leaks). Problem still occurs with the idle and hesitations on acceleration. I cleaned out my MAS and still has the same problem. I have a new EGR valve but did not replace it yet. If the new EGR valve doesnt work..then I am stumped on what it could be. Again this is the first real problem that I have faced with my LS so far. If there is anyone out there that might know what can be the problem I would greatly appreciate your feedback.

I HAVE A 2001 LS, AND I JUST TODAY HAD TO GET THE 2ND COIL REPLACED, AND NOW HE IS SAYING SOMETHING ABOUT ME NEEDING SOMETHING CALLED A VALVE COVER GASKET, WHATS UP WITH THAT AND WHAT'S THE PRICE. HAS ANYONE ELSE HAD THE SAME PROBLEM.

Replying to: mzbatts (Jan 27, 2008 5:40 pm) The valve cover gasket is leaking oil which gets into the spark plug wells and that contributes to the COP failures (but isn't necessarily the primary cause). It does need to be replaced and yes, it's common but once repaired should not happen again. I'd have all the coils replaced while they're in there. |

| I am having a problem of what I thought was random misfiring. I had the cop's replaced with a complete tune up (154000mi). I still had the problem when I left the dealership. I took it back and they found that the fuel pump could not produce enough pressure at the higher RPM's. The cost to repair is $640.00. The car runs great unless I kick it into a lower gear and accelerate. So, I decided not to repair. I am going to replace the car in April. Probably with another LS. | |
I replaced the coils and the spark plugs and valve covers but it's still misfiring. What should I do? I put autolite spark plugs in it instead of motorcraft will that make a difference.

MY 02, 3.0 SIX CYLINDER, LINCOLN LS, HAD A RARE RANDOM MISFIRE, FOUND OIL ON LEFT AND RIGHT REAR PLUGS CAUSING A SHORT, I ORDERED NEW VALVE COVER GASKETS FROM AUTO ZONE, WILL THESE WORK OR SHOULD I RETURN THEM AND GET FELPRO GASKETS? I ALSO HAVE NEW NGK PLUGS IM INSTALLING, WILL THESE WORK OR SHOULD I PUT IN MOTOR CRAFT, IM ALSO INSTALLING ALL NEW COILS, I DONT WANT THE PROBLEM TO HAPPEN AGAIN. ONLY OTHER PROBLEM WITH CAR IS SOMETIMES MY STEERING MAKES A HUM OR SQUEAKING NOISE WHEN STEERING AT LOW SPEEDS OR JUST TURNING THE WHEEL, I PUT IT ON MY CAR LIFT TO TRY TO FIND THE PROBLEM BUT IT NEVER DOES IT WHEN ITS IN THE AIR, IT DONT DO IT ALL THE TIME, JUST WHEN MY GIRL FRIEND IS WITH ME IT SEEMS LIKE! I THINK IT DOES IT ON REAL COLD DAYS WORSE THAN WARMER DAYS, ANY HELP IS GREATLY APPRECIATE..
