Multimedia Exchange - Vid inside-how slow is my bone stock 99 T/A

This is my first ls1 f-body, just did a full tuneup on it and there are no codes. My 04 GTO felt quite a bit faster. Its bone stock except for a few free mods 76k a4 2.73 rear. It won't even spin the tires if you try.

The 2.73 gear doesnt help at all!

Leave the gears and add a stall ASAP!!!!

If you can't spin the tires in your RWD muscle/pony car you should probably sell it.

holy hell, think my 2.2 cavalier is fast than that... 3.73s, stall and exhaust

looks like you might be missing like 6 spark plug wires,or your driving into 100mph winds,either way its not good

3.42 and retune set the shift 6200-6300rpm you'll think you added nitrous... :D
Are you sure your TB is opening all the way? I'm not joking I drove a couple of bone stock F-bodies with 2.73 but that was very slow 250-270rwhp maybe?

yeah that was slow a$$ hell.get 3.73 and a stall asap

Holy crap! And I thought my Z28 was slow (also stock)!

even bone stock with 2.73's shouldnt be that slow. theres something wrong.

It definetly feels choked off, meaning like it sounds like its running hard but as soon as you open it more than 1/2 or so and gets above 2k rpm it feels like something is holding it back....clogged cats? Its faster at half throttle than at WOT also by a large margin.

What's a "full tuneup"?

Plugs/wires, air filter, pcv valve, fuel filter, oil change. Sadly most of the stuff I replaced was in good shape.

how many miles? is the mat not causing the gas pedal to go down all the way?

I thought you meant that you actually had it tuned. Compression / leak down test will tell the tale...

wow that is super slow. I wuld do a compression test. take cats off get a tune and see how it runs.

Taking cats off tomorrow, it gets full wot even w/ the mat in the floor, 76k. The half throttle feeling stronger is what gets me.

I remember when a buddy of mine and I went looking for to get him an f-body. We drove the crap out 10 different cars and were LS1's and stock. There was a huge difference between them. He ended up getting an A4 w/2:73s and it had troubles spinning the tires.

instead of taking off the cats just remove the o2 sensor after it gets hot and see if the issue goes away if not check the back pressure

I've experienced that very same thing in a chevy truck with 5.3 that turned out to be clogged cats.

You could check them with a back pressure gauge if you can get your hands on one. Like unit213 said, compression test and leak down test would be good idea as well. Theres quite a few things that can cause lack of power like that. i wouldnt spend any money on mods until you get it running 100%.

Do all the wheels spin freely with the car jacked up? Dont wanna overlook something dumb like a seized caliper or something.

OP, I'll try to get a video of my 0-100 tomorrow and upload it for reference. That way we can compare and everyone else can tell me if my turd is too slow too.

Wheels spin free, verified that checking gear ratio in the driveway. I have access to lifts 24/7 so I figure I can run open manifolds for a short time to see what it acts like. I'm hoping its the clogged cat thing, that millisecond when you put your foot down it acts like its gonna take off and then its just got nothing. Its hard to put into words without feeling it I guess.

Compression test/leak down, wouldnt invest anymore time/money untill that was done, stock a4 with a crap gear isnt going to break the sound barrier anytime soon,

wow...ok...well...what a freakin turd!!!

:| sorry bro...but DAYUM!!!!

Another way of checking the cats is with a laser temp gauge. Before temp/After temp, Left temp. vs. Right temp. If there is an issue it should be creating loads of heat in the cat.

Also when i had my 2.72 Z28, I swapped in 3.42's, lid, and catback. Holy crap it was like a whole new car! I also went through 2 sets of cats on that car when it was bone stock, It would fall on it's face and sound like a helicopter. :lol:

first i read all the comments then watched the video and im blown away that was slow. I sware the 2001 bonneville SSEi 3.8L S/C would give that a good run i had years ago.

That engine is missing a ton of power. Probably 100+hp.

Don't bother with the exhaust. If one or both cats were restricted you wouldn't be able to spin the engine up as high as you did in the video. You would hit an RPM wall, like a soft rev limiter. Usually in the 2500-3500RPM range.

If you had low compression or a misfire, you'd probably notice that at idle.

You've got either a bad/contaminated MAF or the PCM is pulling timing (false knock, poor fuel delivery, etc). Cleaning the MAF is part of a modern tune-up.

I agree with post above, i really dont think its a exhaust issue,like i said a compression test/leak down doesnt cost alot of money, if that was my car that is the first thing i do, then once that was ok i would go down the list, that car has some kind of issue, i mean thats close to stock 2v territory

Marc 85Z28, thanks for you're input and I believe you may be on the right track. I pulled drivers side cat today and it was perfect. The motor runs perfectly smooth at all rpms so no mis-fires but could it still be low compression? Uses no oil and plugs look great, as does coolant/oil.

I did clean the maf when I tuned it up, forgot to put that. It had lots of dust/small rocks stuck in the screen. Hosed it all down with electronics cleaner and cleaned the screen out with fine wire. It has a tick in the motor at idle but that's the only time you can hear it. Could that be enough to cause false knock? I need to identify it though. Checking fuel pressure should be my next step and its easy.

Wow, 5 seconds to get from 30-60, and 15 seconds to get from 30-90.

lmao. the whole time i was reading the thread (before watching the video) i was just hoping... i hope its not faster than mine. mine feels pretty slow, not sure if its because im just used to it or what.

^x2 lol I was like damn I think mine feels slow, but yeah you defiantly have a problem, when mine was stock with 2.73s it was still a lot faster then That, run a compression test and post up the results

Find a buddy and swap MAF's. My old Trans Am acted like that although not nearly that bad. Changed the MAF and it got a lot better.

Its worth a shot.

If you had that much debris on the screen, you really should replace the MAF and then figure out how all that crap got past the air filter - poorly fitting airbox lid?

Its the maf, unplugged it and the idle cleaned up even more. Jumped in and noticed it even after just putting it in gear and rolling out of the driveway. Then I made this quick vid. Off to find a new MAF! Anyone who's been following this got any handy?

The Cardone remanufactured MAF is decent. You can get one at Advance Auto for $80. Buy it online and use promo code VISA. :D

I have a 75mm maf and an 85mm maf.
