#10 of 19 grand prix ??? by adam270 Mar 30, 2007 (1:55 pm)
My wife has a 1999 Grand Prix with 170,000 miles with a 3.8(no supercharger) The problem is when Im cruising around 55mph and then slowly accelarate it chuggs or maybe missing. I replaced plugs last year. I just replaced wires and coils today. The first few miles it felt great real responsive, then about 20 miles later it started misssing again. Its real noticable at takeoffs too unless I floor it. Any help would be appreciated Replies to this message: mawilliz1 (Nov 25, 2007 2:24 pm) mvautaw (Dec 21, 2007 8:22 am)
#11 of 19 How can u Change a 2002 Pontiac Grand Prix's Air Filter ? by craig32 Apr 13, 2007 (3:19 pm)
The book simply says "unfasten the housing hooks, and pull the housing back", but there's barely 1 inch of movement (& the stock filter's about 1 1/2" by itself.   Is there a trick to changing it??? Replies to this message: mawilliz1 (Nov 25, 2007 2:27 pm)
#12 of 19 Vibratation at 1000 RPM by chriscafepress Apr 15, 2007 (9:02 am)
Hey guys...got a quick question...   I have an 05 GP. Everything is great except for one thing.   At 1000 RPM I can hear a vibration from what appears to be right in front of the glovebox. Does anybody know what this could be?   It only happens when holding steady at 1000 RPM?   Thanks in advance!

Replying to: adam270 (Mar 30, 2007 1:55 pm) I had the same problem and it was the catalytic converter backing up the exhaust, preventing the engine from running properly. Its actually a very common problem with GP's. Have you had it changed yet?

Replying to: craig32 (Apr 13, 2007 3:19 pm) pull back a little harder and swing the whole thing up (tube and square part).

Replying to: foxyroxy1 (May 04, 2007 1:44 am) It is hard to find  it is on the left side (pass. side) back by the fire wall down at the bottem you will need a long neck funel    Gearr

Replying to: adam270 (Mar 30, 2007 1:55 pm) adam270, the same thing happened to our 2004 3.8 GP w/ 40,000 miles. we had to replace the transmission. its might be worth getting a new car.
#19 of 19 Timing belt by matt9404 Feb 28, 2008 (3:51 pm)
I have a 2004 GP, and I wasn't sure when I should get the timing belt checked out. I've heard different mileages like 80,000 and 100,000 and although my mileage isn't too high yet, I know that if it fails, it can do significant damage to other components in the engine.   Does anyone have any information or recommendations about if and when to check/replace the timing belt? Thanks.
