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!

 

guys i gotta figure out what the hell is wrong here, Anyhelp would be much appreciated

 

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.

 

TTT

 

Just did headers?

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

 

BTW did you Mufflex Y line up with the Hookers?

 

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!
