Default CQ is having some trouble starting

Tried to start it up the other night and it took longer than normal to turn over, about 4 or 5 seconds. Drove it around and it performed okay, although I'm hearing an exhaust rattle now. Turned it off and it started right back up after being warm.

Just replaced the O2 sensor, fuel filter, injectors, and had an exhaust leak repaired along with new gasket between em and exhaust.

Haven't tried to fire it up since then, but I will tonight to see if it happens again. Any ideas where to start looking? ISV?

Default Mine has a hard time starting too...

We don't know what is the problem yet but we'll change the fuel filter and try it back.. I already changed the spark plugs but it didn't do anything good.

I think it may only be my fuel filter since it's the old one from the old engine and hadn't been working for a while !

No clue about yours though.. hope this helps

Possibly a temp sensor somewhere in there might be going bad.
