General Maintenance & Repairs - rough start

My camaro has been starting up rough lately on a cold start it starts up perfect and on a hot start as well but when the engine is warm like i left the car for like an hour its not all the way cold it just doesnt start up smooth its been really rough what can be the problem

Is the SES light on?
How many miles are on your car?
You may need new plugs, fuel filter.... TUNE UP.

MAF is what runs things when you make a cold start....clean the MAF with MAF cleaner. Also, lift your lid and spray the hell out of the IAT sensor thats in the inside of the lid with the MAF cleaner.

Other things that cause rough cold starts can be easy stuff like spark plugs, wires. To very bad things like leaking valve seals in the heads that crud up the spark plugs each time you shut the engine off. Then when you go to start it up, that crud has to burn off the plugs before it runs smooth again.

.

Mine was caused by a bad fuel pressure regulator.

well right now i have 95000 miles no ses light my ses light was on due to a bad cat but thats all fixed but its only rough on a hot start like if i drive the car and leave it for about an hour and try to start it up its rough really rough so can it still be the maf or is it just time for a tune up?
