The car hasnt ran right ever since the lt install. It will barely start and will not idle at all. I drive it and it will not accelerate worth ****. It is like I'm wot in 6th gear at 40 mph...abotu how fast I can accelerate. I just put in brand new ac delco o2's. Brand new o2 extension. Everything related to a lt install is brand new. I cannot figure out what could be wrong here... oh it throws a code 13 every now and then but it goes away and comes back...

Hmm vicous header leak? Bad O2 connection. A stupid question but did you plug up all of the oil AIR and EGR stuff.

What does code 13 stand for?

Well it could be a viscous header leak but the damn thing wont idle so I cant get out and feel around the headers for leaks. I need to check for continuity at the o2's to see if that is a problem. I plugged up the 2 holes in the back of the intake and my headers dont have emissions so I didnt have to plug those.

I just took out the a/c and intalled the delete pulley if that helps. I just ripped out all the lines up to the light green box up under the cowl and did nothing else. Did I forget something for the a/c removal?

New ovc plug wires. Positive they are wired right. I'm just dumbfounded as to what is wrong here...

I have'nt read all the posts in here, so i maybe repeating or soemthing, just wanted to put in a little input. First I would say that it would be something emissions related since you removed it all.....BUT that could never cause the problems as drastic as you say they are, so honestly i think it is a problem with one of the o2's. Either the extenion is bad or something, but maybe its in harness, or a burnt wire. Do you have a scanner? COuld you check to see the o2 reading if you get a chance?

Don't have a scanner but wish I did. And yes, the problems are not exagerated. My car will go 0-60 mph in about 30-40 seconds wot.

Jeez, what all did you take off when you did the headers. Why wont the car idle? What does it do?

The engine will turn over and over but not fire up without depressing the gas pedal. When the pedal is depressed while I crank it, it will fire up after 5 or 10 seconds and maybe give me a loud pop (backfire) every once in awhile. It runs somewhat smooth but absolutely will not idle, it just dies. So I took it for a spin and it was just slow as ****. It will rev up pretty good while not under load but as soon as it's in gear and I punch it, it just doesnt go.

I took off the egr, air, and the a/c. I plugged 2 holes in the back of the manifold for egr. I left the solinoid as is and plugged in. I left the 2 barbs on the solenoid open. Maybe the solenoid is f'in me over?

I ripped out everything relating to the a/c up to the green thing under the cowl on the passenger side. I installed the a/c delete pulley.

I installed taylor ovc plug wires.

New ac delco unheated o2's and an extension for the passenger side (the driver side reached without an extension).

True dual 3" x-pipe exhaust ending with bullet mufflers before the axle. There is a slight leak at the collecter to exhaust joint on the passenger side.

This is all I did and the car's been out for 3 weeks for a freakin header install. Help!
