Hard cold starts and dying while driving Hello,
I have a 2001 Firebird with a built ls2 and I’m having problems with the cold start and dying at stops when driving. The hvac vacuum line was not hooked up when I bought the vehicle so when I got it home and plugged it in I started having these issues, unplugged it and issues went away. I went had a tune on it and it seems the motor was tuned to speed density and is not running boost nor has a mass airflow sensor. The guy that tuned it recommended a new throttle body as it had a cheap Holley knock off in it with new Iac and tps. I replaced with a Nick Williams tb and new sensors. The problem consists. Any ideas?
