car is running like s**t
car is running like s**t my camaro is running like **** last night it dropped all 4 cylinders on the drivers side. i can barely drive it but when the computer goes into limp mode it is fine?? i changed out the o2 sensor and that made no difference what is the matter it used to just do it in the morning but now it does it at all speeds and all gears. i have to go to freeport tonight should i be able to get there in limp mode and not hurt anything??? help im a carb guy not a f/i guy.
Thats wierd Billy. First thing I'd check is all the easy stuff, like make sure all connections are sound, (coil pack harnesses as well as the injector harness). May want to check the plugs as well, but I doubt that'd be the problem.
Wierd problem for sure, hope you get it sorted out!

ok going up to port aurther it was fine SES light went off and it felt like it should. got all the way there with no problems (except the rear end sprayed gear lube all over the back of my car) butt other than that she ran great! coming back it ran a little rough but it was cold so and then when i got stuck in traffic (BIG wreak on I-10 moved like 5 feet in 1 and 1/2 hours) but then it started running funny? backfiring spitting SES light flashing all of that stuff and then i noticed i had half a tank left. so today i filled back up and turned off the SES light and now its running fine any ideas? the codes were 02 sensor dirvers side unusualy high reading

Am I the only one that believes by the sound of things it has been severely abused? At first I though you just had an odd issue but now that you mention gear lube flying everywhere, I think it may have been a little neglected?

Billy, just an idea.
Most people don't know this, but the LS1 computer will pull timing out when the knock sensors sense knock or detonation. Thats a good thing. However, it will not add the timing back in until it senses that the fuel level has been raised. A friend's LS1 was runing slower than we expected one night and slowing down. He added a couple gallons of fuel, and the very next run picked up about 2-3 mph.
The engineers did this to compensate for bad gas. Their thinking is "Well it is detonating because of bad gas or lack of octane. That problem will not be solved until fresh gas has been added". This is the reason some cars seem to run stronger right after you fill up, and another reason that some cars with exhaust rattle always run like crap(the engine senses the rattle as a knock, thus pulling timing.)
I don't know if it ties into your problem, but you said it runs better after you put fresh gas in it. Next time is starts to happen, drive to the nearest gas station and top the tank off, see if there is an immediate change or not. Another thing, where do you buy your gas from? If you get your gas from the same station every time, there may be a problem with their gas. Believe it or not, there ARE some stations out that dilute their gas, or may even fill the tanks with the incorrect grade of gasoline in hopes of boosting profits. You may want to try changing stations. FWIW I've always had good luck with Shell gasoline.
Good luck and let us know!
