Default Rough Starts??

Recently my camaro has been starting rough every now and then. Its like it does want to turn over. It always starts on the first crank, but sometimes it starts really rough. I thought it was driver error but I am starting to realize its not me. I heard the my SLP ported TB maybe causing it to do this??? Any ideas why???

I have a similar issue with mine. It starts fine when the engine is cool, but if it's hot I have to crank it twice for the engine to turn over. It's really weird.

Do you have a ported TB? I was told that maybe the problem, if I get some time I will put my stock one back on and see if it helps.

Does it have these rough running starts AFTER the engine is up to operating temp...or only when its a cold start?

First thing would be to clean the MAF?

But I would get a scan to see how your 02 sensors are switching while the engine is running.
