View Full Version : Anyone else have a "weak" 3400?

My 3400 feels like a 4 cyl. If I didn't know if was a V6, I would think it's a 2.4 LD9.

I've driven a couple of 3400 SE GA's that would roast the tires if you punched it from a 10mph roll. With mine, the tires don't even squawk and the tranny really feels like it's starting from second gear.

My engine has piston slap for about a minute when started cold. Doesn't burn a drop of oil though. It only has 55,000kms (33k miles.)

Anyone in the same boat and if so, is there a cure? I've done a Motorvac fuel injection cleaning and a new fuel filter so far. No help there.

from a 10mph roll you should get a little spinnage but your and my defination of "roasting tires" must be completely diffrent.

Smoke and burnout marks arent going to happen in a stock v6 grand am just from punching it at a stop.

When you have an SC or a Turbo, tire-roasting is a reality. :metal:

When you have old RSA tires that look like slicks, you can roast them easy.

Ok, roast is exaggerating a bit then. But with the GA's I drove, the tires would break loose easily at a 10mph roll but with mine I don't even get so much as a chirp.

I'm not interested in smoke shows or burnout marks either. I'm just concerned that my lack of power may be an indication that my engine will die a premature death.

And we all complain when they fall apart with 20,000 miles on them? I wonder why...

Def not here. I have no trouble peeling when I stomp the gas. I get pretty well planted into my seat when I floor it. Haven't had a chance to get to a track. The nearest one is almost 2 hours away, unless I'm mistaken. Anyone know any good tracks in central Maryland?

Perhaps something is clogging the intake on your car.

BTW, how much did that Motorvac injector cleaning cost? The previous owner of my GA didn't take very good care of the engine. Rarely changed oil, never changed the air filter, never rotated or changed tires. Currently using Royal purple fully synthetic oil, Fram Air Hog in my stock intake, and Venture high performance tires. Think I got a leak in my radiator, but the radiator sealant I put in seems to have patched it up for now. How much does a replacement radiator cost and where can I get it where it doesn't cost me an arm and a leg. But I only paid $3k for my 99 GA GT. :tongue2:

back when i first drove an alero gls, we had just gotten it and it only had 31,xxx miles, on some types of roads(not dirt!) it would chirp the tires a little when you hammered the gas at about 10-15 mph....not anymore though at 70,500-still plants you in the seat though. gotta love torque. oh also (asked about this before) the GAGT has a diff. final drive than an alero 3400
3.05 and 3.29 :1

Hmmm, go to http://calid.gm.com/. Enter your VIN, select PCM & Normal programming. This may only apply to '99 3.4's but:


There is a known issue with our cars and the knock sensor. Specifically, a calibration was introduced to deal with "Lack of power" because the knock sensor would mistake normal engine noise as pre-detonation. If you do not have the latest calibration, this _could_ be the issue. You can go to a GM service shop and have the new calibration applied, or get a DHP PCM. ;) A typical shop will most likely charge you about $60.00

The noise you hear when you start up: Are you positive it is really detonation? Or is the noise coming from your valve train? Just about all GM 60 pushrod engines with roller lifters I have ever heard on a "cold" start will make valve train noise until the oil begins circulating through the passages...

can u go to any certified gm shop to reprogram that knock???

It's not really knock, that is the problem. The PCM thinks there is knock due to some normal things going on. In short, you can go to any shop that has a Tech-II. Expect to pay somewhere in the order of $60.00

An alternative would be to buy a DHP PCM, since it has the latest and greatest calibration.

When my ga was stock i could EASILY squak the tires, even at a 10mph roll. Now i can squak them at about 20 and at a stand still i can litteraly roast them when i put the pedal to the floor almost get half way through 2nd gear before they stop.

FWIW, I've been selling Pontiacs for 5 years now, and have probably driven at least 50 different 3400 GAs. A GA GT, from a dead stop, without power braking, should have no difficulty burning rubber all the way through first and part of second. Don't ask how I know this... :D
