List of problems with 98 Camaro Z28 I am having a few issues
The car does not start right up. it takes a good couple of seconds
the fuel gauge does not read my fuel proper. the gauge just moves wherever it wants
when the car is ready to shift to 2nd, it kicks very hard into 2nd. (automatic)
i have 4 CEL's
P0420
P0430
P0171
P0174
Any ideas?
I think there may be a vacuum leak aswell. I hear a loud hiss noise around the intake area.
Could a bad PCV Hose cause these issues? which vacuum line could actually cause problems like this?

Vacuum leak and the catalytic converters are bad. Any work done recently?
Not too many vacuum hoses on the LS1 - take a can of carb cleaner and spray around the engine. Listen for an increase in RPM and you found your leak. PCV hoses can rot out on the back of the engine, check for that as well as swelled/blown intake gaskets.
edit: exhaust leak could cause this as well - but since its starting hard i'd think vacuum leak

On older, high mileage LS1s, the ring gasket/seal for the EGR pipe's nipple into the top of the intake manifold gets old/drys out/goes bad often.
Check to see if that "hiss" is coming from that area, as this is a very cheap piece to replace ($.99 @ Rock Auto, $1,99 for a Fel Pro locally for me).
MANY/MOST on here would NEVER know this since the EGR system (along with the A.I.R. system) is the very first thing they dump/get rid of on these cars when they get them.
