Would semi bad gas drop me to the lower tables repeatedly?
Would the lower tables prevent a burnout without power braking the car on wet roads?
What other issues would be causing such an extreme power loss without setting a cel?
Is my slow driving style somehow making the computer conservative?

L99
3400miles
GM break-in
Daily driver and seldom abused.
TC and TQ off (7 second hold down)
Always use 93 Octane

I have done the fuse pull three times in two months. The other two times it didn't feel right when I got on it at highway speeds. Night before last I decided to do some playing from a stop so I took some back roads home. It was misting rain and I figured I could get sideways a bit without really roasting the tires on dry pavement. To my suprise I didn't break the tires loose. It took launching at 1k with my foot on the brake to spin them. As it hit second it bogged and stopped. Now with the roads being wet I saw this as a problem. Did the fuse pull that night along with the tcm fuses. It was kind of raining off and on all the next morning and was still pretty wet when I took it out after lunch. 3/4 throttle from a stop and I was breaking loose all over the place. Seemed like it had gobs torque and power. Parked for about 20 minutes and drove it hard (for me anyway) home. Later that evening on dry roads it felt just like the night before. I had to power brake to spin the tires. Seeing as how I don't really get on it from a stop I couldn't tell you if it has always been this way or if this is pretty normal for the auto. I wouldn't mind getting it dynoed to see but it kinda gets me in the backside that it costs a couple hundred just to verify the problem exists.

here are a couple of suggestions and experiences I had with my L99 when fully stock.

1) It won't spin the tires unless you are at a dead stop and give it full throttle by mashing it quick, don't ease into it. If you are idling out or easing into it then it just wouldn't break loose. So you shouldn't have to break stand, however keep your left foot on break and then simultaneously lift your left and mash the gas with right foot and it should break lose consistently, no need to hold gas and break at same time to get RPMs up.

2) Try it in Sport mode by shifting it to "M" and then try it, don't need to use paddles just let it shift for you.

3) Time your car to 60 MPH using an iphone or some other accelerometer and see what kind of results you get to compare to others, see the fuse pull thread for various times for the L99.

Thanks for the response. I was in Sport mode and did #1 as you have laid out. This was with a little wetness on the road and all I did was shoot forward. There was no easing into it, I hammered my foot to the floor. It might have started to come loose about 3/4 into first but I started letting off right after. Not sure I have anything to time the 0-60 with but I will do some checking.

JohnInSoCal · 02-21-2010, 09:07 PM

I suppose it's possible you keep getting put into the low octane table, what's your VIN ? If you have an early one maybe they have made some changes, taking it in and getting all updates for your computer might help you out. They should be able to hook it up and see if indeed you are current set for the low octane table. Also maybe mix up the gas stations you go to and try some different ones.

Stock it should be breaking the wheels loose, especially on wet pavement so I would say something is definitely not right with the computer.

brAnd7onX · 02-21-2010, 09:37 PM

Your problem might have possibly been the easy break-in... Every car has a different horsepower output and depending on how the car was broken in it can affect that.

Yeah I am almost on empty and I am going to hit a different one in the morning. Funny thing is the one I go to now is only 2 years old and I would think the gas would be fine. That place is packed daily..

Thats true although I am not sure I agree with that being permenant. Thats a different issue though. If it was the way the car was broken in the fuse pull would not be a major kick in the backside.

JohnInSoCal · 02-21-2010, 11:49 PM

> I would think the gas would be fine. That place is packed daily..

you are probably right, however almost nobody would notice a difference between 93 and 87 as almost all cars are tuned to run on 87 just fine and the camaro can too, however the timing is pulled which effects performance.

In california they do testing to ensure premium is actually premium and owners can get into serious legal trouble and do prison time if they are scamming people. However given all that just a year ago there was a massive bust and scam going on here in socal when gas stations actually rigged the pumps to charge more per gallon than the advertised price. The testing that CA did to make sure the pumps worked only checked the first 5 gallons, so they rigged the computers in the pumps to alter the flow after 5 gallons and nobody noticed it until years later. So anything is possible.

Screaminz2002 · 02-22-2010, 06:25 AM

Very true. I think Texas does their testing every four years but thats only the amount charged and not the grade. I could be wrong. Either way I hit one this morning I never stop at due to the buisness they do. Going to pull the fuses at lunch and see what happens.

I also failed to mention that I have some noise in the front end. It's in a thread here: http://www.camaro5.com/forums/showthread.php?t=63007

I doubt the two are related but you never know. The dealer seems to think it's coming from the power steering pump but is researching it for a solution. Sounds like bad bearings to me. It also sounds like an air pump since the belt change and thats for sure the pump. Going to call them this morning and tell them about the power loss. They are nice people but not well versed in the Camaro yet and really don't seem like enthusists.

Russell James · 02-22-2010, 08:55 AM

Not being able to spin the tires, even when wet is not a good indicator of power of if any problem exists. 20" wheels and tall gearing, makes it a dog off the line. I've driven L99 autos several times, and never could squeek a tire.

Thanks for the info and reply. Could you elaborate on the details of the ones you have driven? Such as the mileage and if you were trying to get the tires to spin etc.

Screaminz2002 · 02-23-2010, 06:55 AM

Anyone else with a L99 want to chime in?

Pulled the fuses and seemed good driving home. Got in it ths morning and it seemed good but it was also 37 degrees and wet so..

Didn't really try and get on it much.

There was a post in the fuse pull 30 pages about getting a cold air intake to lean out the rich granny driving. Anyone have experience with this?

I don't really want to get the dealer involved in this issue unless I have too so thoughts and opinions would be great! I also don't want to slap a cai on if it's something more serious.

JohnInSoCal · 02-26-2010, 01:44 AM

check the l99 fuse pull thread, I think this date is close or before a reported problem with the computers. L99's after this date have the fix but yours may not, check that thread for the exact date, if yours falls before the date of the fix then you can take it in and a reprogram of your computer will fix it.

Screaminz2002 · 02-26-2010, 12:23 PM

Thanks for the info. Honestly I havn't read the entire thread yet. I made it to page 14 or so and skipped to about 24. Will have to go back and look for the date.

Edit: I can't seem to find a date? Trying to get back to the dealer but my schedule has been crazy lately. Can't get my service guy to call me either..

I should count myself fortunate then. I would not even consider nailing it on wet roads. Mine will roast the tires from a stop off idle, no brake. TM stops the fun as it shifts 1-2. Otherwise no complaints. vin 35xxx. I did the fuse pull once for good measure, but I don't think I needed it. I think it is in the gas. Try another station. BP or Shell is all i've used.

Sherwood SS · 02-26-2010, 01:59 PM

Just tried to spin my tires in sport mode and it was a no go as well. I have an L99 with 1800 miles. My vin 2G1FJ1EJ0A9176965. Only using 93 octane here. I haven't read or tried the fuse pull, but it looks like I need to. I broke mine in semi hard. Let me know how it goes.

Roger Ramjet · 02-26-2010, 02:34 PM

Get an ECM & TCM tune - you will never have this issue again! And, you will smile EVERY time you touch the GO pedal.

Screaminz2002 · 02-27-2010, 07:41 AM

I am so aggrivated with my dealer. They tried to tell me one rolled off the truck sounding just like mine. I replied with that's crap as I heard 26 of them last week and none made the noise. They called GM and no reported complaints on the issue so they want to wait until it getz worse. How can I get them to work on the power issue when they won't even fix a bad pulley. I am about 99% sure that's all it is but will post a you tube later and let you decide. At this point I might as well tune it and repair it myself. Wonder if I can tell gm to bite me and get money back for a warranty I will never use.
