• 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.

    Cylinder 4 Misfire (Fuel Injector?)

    I have a naturally aspired 06 Grand Prix that is throwing the code for a misfire on Cylinder 4. I've swapped wires, plugs, and coil pack, but it is still misfiring. I actually have visually checked the plug and it's firing as expected, so I don't believe it's on the "fire"side. I'm now...

    Oil Pressure Question

    I have an 06 Grand Prix with a 3800 Series III engine with just over 300k miles on it. A while back, the engine developed a "tick" coming the rear valve train. My neighbor (who is a boat mechanic and shade tree car mechanic) and I removed the valve cover, and all the valve cover and inspected...

    Removing MAF Sensor from Housing

    I'm replacing the Mass Air Flow sensor in my 06 GP. The local auto parts had the sensor only on the shelf, so I purchased that rather than ordering a sensor with housing. How does the sensor remove from the housing (Pull out, twist out, snap ring, etc)? I just got the sensor today, so I haven't...

    Valve Clicking Diagnosis and Fix

    My 06 GP has 265,000 miles on it, but a couple of weeks ago, there was a clicking noise coming from the valves at the rear of the engine. I removed the valve cover and found that none of the valves seem to loose. All the valves look to have oil at the end of the pushrod, but I can manually apply...

    Fuel Pressure on 06 GP

    I have a baseline 06 Grand Prix that I've recently had problems with misfiring under load (higher RPMs, pulling a hill, etc.). I replaced the plugs and wires back in the spring and replaced the coil packs last week. When I connect a code reader, it gives me the P0300 code for multiple...

    Brake Pedal Vibration Issue

    So I'm seeing something on my '06 Grand Prix that has me a little lost. I figured someone here has seen the issue, and can give me a little guidance. When I'm driving slow (5-15 mph), there is an odd noise that I believe is coming from my brakes. The best way I know to describe it is like...

    Replacing Washer Fluid Level Sensor

    I filled up my washer fluid the day on Monday, and yesterday, I noticed that I had a low washer fluid warning on my '06 Grand Prix. I popped the hood, and checked for fluid in the reservoir. When I opened the reservoir cap, I notice the float from the level sensor floating on top of the washer...

    Persistant Heater Issue

    I have a 2006 Grand Prix that I've been having problems with the heat on for the entire winter. Back in early December, I discovered that I was only getting barely warm air from the heater. It was about this time that I noticed the engine temperature not getting up to where it needed to be. I...

    Coolant Leak Location Identification

    I have a 2006 Grand Prix (Base Model) with 200,000+ miles. I have a fairly significant coolant leak on my car. I finally located it, but to be honest, I can't figure out what the source of the leak is. I hope someone here may can tell me what I'm looking at. I had a slow leak a couple of...
