I wasn't sure where to post this so i thought here would be a good start.
Ok guys here's the deal, i just got done installing my hooker Lt's y-pipe and hooker catback. So i'm out having some fun and a friend of mine pulls up next to me and i'm in second at about 2500 rpm's and stomp it and double clutch it. well i shift up to third and slow down then turn the corner to my neighbor hood and give it a little gas in second and it kinda stutters then goes sorta. Well I pull into my drive way and put it in neutral and slowly rev it up and it doesn't do it, but if i goose the throttle then it stutters. I noticed that my oil pressure was wobbling around at aroun 37-39 psi. I shut the car off and let it sit for a minute. Well while it was sitting I checked the oil and it appeared fine, then i made sure i hadn't fried any plug wires and they were good. WHAT THE HELL IS GOING ON WITH MY CAR?! Oh and I don't know anyone within 30-45 minutes that can A-tap my car and i also don't own it. Any help would be great. sorry about the long post, but this has me pretty worried, thanks in advance!

Could it possibly be the oil pump?

Check your spark plugs and spark plug wires. I know it sounds dumb, but that was the problem we had on an 01 SS last season. We took it to the dealer for a code scan and it showed a ton of misfires. Got it home and popped the hood to see the #4 wire hanging on the end of the plug. Also, make sure you put some electrode grease on there.

I'll give that a shot and let you know how it worked when I'm done.

Ok i checked all of the plug wires and two were loose. I pushed those back on as tight as I could and started it up. Well it still shutters a little when I give it gas (does it need some runtime to remedy this?). I took it for a drive around the neighbor hood and it still feels like it's pulling timing or something. especially from a dead stop. Any other ideas?

I also revved it from under the hood and the motor shutters a little and then smooths out when i give it a good rev.

Just did headers?

Might want to check the O2 wires and connection sometimes they get burnt to damaged in a header install.

Not very well, there was a lot of cussing and getting pissed off, I also had to cut the I pipe shorter on my hooker catback and have it welded to the 4" to 3" reducer. Major pain in the ***
I does sound really good though!
