ss1275

i have a 01 ss slp camaro well it has ... super poor acceleration and crappy torque.. it doenst even spin the tires .. i dunno what it could be.. it has a custom tune already installed.... i bought the car a week ago and when i test drove it, the car was runnin damn good.. but now its really crappy .. it has a comp cam but u can tell the idle isnt that great it dies at stop signs and when i put it in gear even after a 10 minute warm up .. any idea of what it might be?.. its not throwing any codes no check engine light or SES light .. any input will be great appreciated...

You may possible have a front O2 about to go out or is responding very slowly. But does it clear up sometimes and the car just launch forward out of no where like you just hit a 200 shot of nitrous?

You need to get a scan using a real OBDII scanner....so you can see how the 02 sensors are switching while the engine is idling.

If its not that, I'd look into a dirty fuel filter or fuel injectors.

the reason for not throwing any codes or an SES could be that "custom" tune it has. sounds to me like some sort of fuel problem, does it smell like its running rich(noticable gas smell)after you drive it for awhile?

i would double check with a scanner the obd system is pretty good at pinpointing a problem like the one you are having. for all you know maybe there is no bulb for the ses light? or his tuner erased some codes permanently prior to the sale
