  1. Rough Idle Questions

    Ok. I have a 1995 Buick Park Avenue, 3.8 NOT supercharged. The car has been running great until recently. About 3 weeks ago, my fuel pump went out. I pulled the tank out, replaced the pump and strainer, and reinstalled it. The car fired up right there and sounded great. About 20 minutes into...

  3. 2011 Buick Enclave dies when idling

    Recently my car has been dieing whenever I am idling at a stoplight, in traffic, etc. Does anyone have any ideas why. Oil has been changed and had a new engine installed, battery is reading around 14V, could it be the an air clogged issue, or fuel filter issue? Any help is greatly appreciated.

    I recently bought a 2011 Buick Regal CXL with the 2.4 ecotec non-turbo (65k miles). I've driven it for about 5k miles and have started noticing a hesitation (misfire) at idle when the car is in drive (it would kind of rock the car). It happens seemingly randomly and at varying degrees of...
  6. Strong smell when idling

    Wife took her 2004 Buick LeSabre to a mechanic (3rd time now), to have a new rack & pinion put in. They said they needed to drop the engine to do it, and since getting it back, every time we stop at a light or stop sign for any length of time a very strong smell of gas fills the cabin. Like I...

    Hello, I and a friend replaced the intake manifold gaskets and valve cover gaskets yesterday due to the gunk build up in the coolant system.

    I have a 60,000 mile LeSabre Custom with the 3.8L(?) V-6 that tends to idle rough when the car is in drive and stopped in traffic. Once in a while, it will stall as I shift from drive to reverse. Otherwise it runs great. Independent technician suggested running Techron in BP 93 octane gas...

    In late spring/early summer, I parked my 1993 LeSabre for about a month while I was out trucking. When I got back and drove the car again, it was over-revving. In neutral or park, it revs like it would if I had the petal to the floor. Sometimes, it has the exact opposite problem. Sometimes...

    2005 Lacrosse CXS. A little under 100k, transmission fluids changed about a month ago, new oil, new power steering fluid line. This happened this morning as I decelerated from 40 to 25 to get into McDonalds. There was no noticeable thud or thump that I can recall, but the car immediately...
  12. Rough Idle ?(not a repeat, promise!)

    Hi all, My 2011 CXL has a rough idle and my OBD link app shows my RPM level fluctuating(Dash Command rules! It's way more accurate than watching the needle for tiny movements) I've had the car throw a P0300 random misfire code(which cleared right away) and I worry that this could be the...
