• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Engine set code for EGR valve and 02 sensor simultaneously. Idles very rough.

    97 SE 3800 SII. 188K miles. I let her warm up for 20 minutes today. It was about 10F here in Michigan. Has been running a little rough at idle through the outrageous winter we've had but no 'service engine light' in 3 years til today. I drove about 1-2 miles and pulled up to a stoplight. My...

    When ignition turned to "on" car shuts off. Battery NOT dead.

    1997 Grand Prix SE with 3800 Series II Naturally Aspirated Fresh off solving a separate mechanical issue with this vehicle I now have this to contend with. 1 week ago I drove it to work, worked 8 hours, walked back into the parking lot and tried to start it: NO START, NO TURNING OVER, dash...

    Serpentine Tensioner replacement

    '97 SE with 3800 Series II Serpentine tensioner bearing seized, causing the plastic tensioner pulley to forcibly spin/melt off. Belt snapped shortly thereafter. Must replace the tensioner. Does any part of this job involve removing power steering lines? Pictures of a typical replacement...

    A new 3800 powered ride gets the LIM gasket/intake treatment.

    My brother and his girlfriend live right next door. She's selling her 1997 Buick LeSabre with 156K miles for $1200. It has the same Series II 3800 that my GP SE has. So, I'm 90% sure I'm going to pick this up. Tires are less than a year old and my buddy and I have done all the oil changes on it...

    Severe engine vibration. Please help.

    97 SE 3800 Series 2 180K miles For a month or so my engine vibrates noticeably at idle. I can feel it inside the car and even almost hear a 'wobble' with the engine bay open. I can feel the engine shake if I touch anything attached to it. This didn't get bad until today on the way home from...

    Sunpro Sport ST Electric Oil Pressure Gauge Install

    Noob electric OP gauge install questions. This is a '97 SE N/A 3800. I'm trying to one-up the stock Buick gauge cluster. I want oil pressure and battery gauges damnit. Possibly even a trans temp or pressure gauge to boot. Electric, not mechanical. Engine health is all I care about at 180K...

    Strange engine tic at low idle. Timing chain hardware, valvetrain?

    97 GP SE N/A 3800 Series II 178,500 miles This is one of those things that's hard to describe but I'll try. This sounds like a little more of a dull, soft clank that changes in frequency with RPM. I'm suspecting timing chain hardware or a noisy accessory but I really don't know where to start...

    Suspension completely shot, save an otherwise great '97 SE 3.8. Please help.

    Old SE needs new suspension. Photo taken last week. To put this in perspective, I hit a small pothole on the drivers side at 25 MPH tonight and the anti-lock brakes engaged... This happens a few times a week. I feel every nook and cranny of the road vibrate through the steering wheel/seat...

    Flashing Low Coolant Light, Coolant Full, No leaks

    1997 Grand Prix SE 3.8 Series II 178K miles Well my 'low coolant' dash light is flashing quickly on and then off in a repeating pattern. I see no leaks. Radiator is full and reservoir is above cold fill line. Coolant is nice and clean. Sorry to ask a question that's probably already been...

    Possible Starter and/or ignition problem: intermittent no start (rapid ticking sound)

    97 GP SE 3.8 NA 176K miles When I turn my key 4 out of 5 times my car does not start. Here's what I hear when I turn the key: -A rapid ticking noise from what I'm assuming is the starter solenoid. -The ticking will continue for about a second if I keep the key turned, and gets weaker the...

    '97 3800 Series II n/a needs exhaust work. Suggestions?

    1997 Pontiac Grand Prix SE Single stock exhaust 3.8 NA Series II 173,000+ miles My exhaust has always been 'noisy' since i got my GP on 11/10/'10. After a drive down a ridiculous dirt road it finally became LOUD! I must have little to no back-pressure right now. Two things: 1. For about 1000...

    I want to REPLACE ALL ENGINE AND TRANSMISSION MOUNTS on my '97 SE 3800, but I'm severely pressed for time, I have to do this possibly over labor day weekend. Can any of you tell me how many engine/trans mounts there are, part numbers, where the mounts are, and what kind of tools I'll need to...

    Strange vibration/pulse. Powertrain or suspension?

    167k miles. At 25+ mph there is a vibration that seems only somewhat affected by speed and more by what RPM the engine is at and whether or not I'm coasting. I first suspected the lower left ball joint or the worn out rear right strut , as both have been making noise for about 3000 miles...

    My car set a code for the first time ever since I've owned it. P0171. 1997 Grand Prix SE with 3.8 N/A. I have a concerning vacuum leak on the "T Fitting" on one of the vacuum lines that comes from the throttle body. One part of the T goes straight to the transmission. In between the T and...
