Is there someone that can help???

test your throttle position sensor. have a look at the maf make sure its not dirty. if it is clean with maf cleaner.

here is a link to set your tps similar to testing, you want to make sure voltage rises and lowers steady without jumping. https://camaroforums.com/forum/93-02...-sensor-70605/

Yeah thank u for info I changed tps already and drill slotted holes and set at .65 and changed and cleaned maf there was a post I seen on here awhile back in 2010 by toruqe is good he had same symptoms but it didn't say if he fixed it thanks

look for vacuum leak

I have every where man even changed intake gaskets

I thought I had internal vac leak so I replaced intake gaskets and sprayed crab cleaner everywhere!!

Do u no what might of happens to torque is good symptoms how he fixed it??? Just asking lol

Have you checked the intake elbow from MAF to throttle valve for leaks or cracks. Was the PCM tuned to handle the 383?
