spark plugs

I have a 2006 Buick LaCrosse CX 3.8L. I recently did a tune up on it, including changed all spark plugs and wires, and coil packs as well. Now for some reason that I can't figure out for the life of me it only is only running on 2 cylinders. The OBD2 says "random misfire. I know, common sense...

I'm replacing the spark plugs in my 1994 buick lesabre and I'm having some problems with the back 3.

Does anyone know how to access the back spark plugs on a 2011 Buick Lucerne 3.9L V6? I think the motor needs to be pulled ahead, but don't know what needs to be removed to do that. Also how do you remove the thermostat and coolant? Thanks.

I just replaced the spark plugs on my 2007 Lucerne CXS. Took me about 8 hours. The front four were easy, probably less than an hour. To get at the back four you have to remove the secondary air injector, which is a bit awkward because it is ALL the way in the back of the engine. You'll need...

Flywheel spins fine, starter is brand new and replaced, no leaks at gasket after...

Hello guys. I recently purchased a 2001 Park Avenue from my friend's mother. The car runs okay overall. The passenger side AC is blowing cold. The driver side blows room temperature. After extensive google search I found that it is likely an air temperature door actuator. I wasn't able to find...

Hey, Everyone, I have been in possession of my LeSabre for 7 months. I enjoy it, but it has given me problems non-stop. Most recently, I was driving around, and it started bucking, the CEL came on and started flashing, and the interior began to smell of rotten eggs. This seemed a bad sign to me...

Hey there! I just recently (about a month ago) bought a '95 PAU with 121,000 miles on it, one previous owner who was an elderly person and treated it well. I can't tell if it's the transmission or just spark plugs but I'm really hoping it's just a plug problem -- Which brand of spark plugs...

I got NGK spark plugs for my 2004 Century, and am just finding out Delco is the best for Buick... So am I fine with these? She's got about 100k on the current ones so I know it's time to change them. They do fit my car. Also, any pointers for changing them? I'm used to working on Honda's and...
