Yup that is a MAF, not exactly the style in your car but similar.

Just remove it completely and use MAF cleaner on it. Let it sit for a few minutes and re-install. Simple and quick but an important thing to do as they get dirty quicker than most think.

Will upping the octane really help as I was advised to use 85(87 sorry) octane?

Your owners manual says you MUST run 91+ octane.

I suggest you never use anything else, unless you wish to replace your motor sooner that you'd want too.

Whoever said using 85 octane is okay, clearly has no clue about the intenal workings of a motor. Low compression with forced induction needs higher octane.

Nice Picture !

In Response to your listing.

Back in the 60s and 70's I was in the drag racing and built a few cars and obtained a degree in Automotive, I have worked on cars for over 50 years, I am sure you have done the same? I feel I know cars and through College and teaching automotive I feel I have a good understanding of automotive and also working in the Automotive filed for many years. I retired back in 2002.

OK we got that part out of the way. Recommended fuel for performance is one thing. If you try and RACE a car and push it then yeah the higher octane fuel is needed. If you drive like an old lady and do not use the power, " Peddle to the Metal type " then you can run the 87 octane fuel. I had my 2004 Pontiac Grand Prix GTP Special Edition ( as seen below ) at the GM dealership and they even showed me in the maintenance manual where you CAN run 87 Octane in the car, more FOR MORE performance the Preferred use of higher octane is REQUIRED. I run a 2001 Pontiac Bonneville SSEI, yeah Supercharged and I run 87 Octane in it and have for years.

NO, I understand that the two motors , the one in the Grand Prix and the one in the Bonneville are not the same motors, even though they were both Supercharged 3800 motors. The 2004 Grand Prix Special Edition has the SFI, where the old 2001 Bonneville has the PFI or BFI as some called it. Not sure if you know the difference ?

Your older 2000 Grand Prix GTP, may have the same old engine as the 2001 Bonneville SSEi which is NOT the same as motor the 2004 Pontiac Grand Prix Special Edition GTP engine. I know as I have had both and I run the 2001 Bonneville SSEI every day on the lower octane with no issues


I got my 2004 Grand Prix GTP Special Edition with 14,240 miles on it and drove it until about 8 months ago and had 71,640 miles on it and had NO issues running 87 obtain fuel in it most of the time and got about 31 mpg on a trip. I sold the car in order to get my wife a new car, it ran perfect the day I sold it. NO Pinging, no issues at all. If you want performance and like to jackrabbit starts and stuff like then then yeah run the higher obtain fuel. KEEP YOUR FOOT OFF THE GAS.

For running like at high performance the higher octane is needed. I run a 2001 Pontiac Bonneville SSEI, yeah Supercharged and I run 87 Octane in it and have for years and it also says in the manual that regular fuel can be run in the engine. NO, I understand that the two motors , the one in the Grand Prix and the one in the Bonneville were not the same motors also, even though they were both Supercharged 3800 motors.

If you do have the older 2000 Grand Prix GTP, it may have the same old engine as the 2001 Bonneville SSEi which is NOT the same as the 2004 Pontiac Grand Prix Special Edition GTP engine.

Ordered, TYVM! ! !

Why would you order that?

Napa sells cans for like 5 bucks man lol

I can't get it where I'm from! It's cheaper to order it than drive to get it unless I have a big order...thanks though!

Better check your prices, or we're getting ripped off here! $9.71 here with taxes or $9.60 on Amazon.

Just like the disclaimer says, prices always change from store to store or state to state.

My local napa is a private owned business that runs 7 stores in the area, likely a reason some things are cheaper or more money. I also use either my AAA discount or my works discount, so I never pay full price lol.

Where can one find how much transmission oil it takes to flush it out & start over from scratch?

Remember no owners manual here.

Sent from my SAMSUNG-SM-G870A using Tapatalk

A pan drop with filter change is roughly 8 quarts of fluid.

There are various threads out there, maybe even a write up or two wwth other info attached for like shift kits and so on.

And using tapatalk sucks ass to try and research anything, get on a real computer to make life easier.

Just helped a friend do a pan drop/shift kit/TC flush, and used over 3 gallons total. Admittedly, some of that was spilled though.
