I agree misfire is usually a plug problem...

 

well they dont make the fast 92 anymore so i had to go the 102 route lol. i just figured what the hell if im gonna do it go big... I have ported 243 heads on the way as well. Should be a nice setup

 

You said that it was running okay at first? If you hadn't of put this intake on then I would suspect an O2 sensor. But here I'm betting that your LTFTs have just worked themselves into the double digits. Good luck.

 

Dude you go from a previously tuned ls1 intake and TB, to a freakin huge intake and tb, without re-tuning and your wondering why its running like ****? Then on top of that your injectors are stock? Your all over the place man, buy the right parts for what you have, go get a tune for your new setup, THEN let us know how shes running, im sure ull be happy

 

well i knew it wasn't going to have the full blown power it should have or be running the way it should be, i just assumed id be able to pedal it to the tuner.

Of course i have larger injectors on the way, and of course i am getting it tuned. Im just surprised the computer couldn't compensate for the extra air coming in to be able to grandma it to a tuner.

Shooting for the high 430s with what im going with.....

 

true, u got a point, sick setup, get us some vids later!

 

I too would recheck to make sure you seated the upper lid back on the lower correctly after you took it apart to drill out for the MAP sensor.

You did drill out a hole for the MAP sensor to read, right?

 

Following.... Can't wait to see how this comes out.

Good Luck!!!

 

Its Fixed!!!

It was the o2 sensor on the driver side. Bought a new one and had to splice some of the old wires to the new o2 sensor because it wouldn't reach the harness. Other than the occasional rpms jumping up when i brake. Car runs fine now. YAY!

 

Look who almost diagnosed it, lol.

 

lol it was wierd because i put these headers and o2 sensors on like a year ago. Don't know how the driver side failed so quickly....

 

Check to see if you melted a wire. That happened to me one time. I replaced both of them when I replaced the burnt one. I also ditched the extensions and just got vette o2 sensors since they're longer.

 

hmm vette o2 sensors are longer eh? What year would i have to use for my 04 goat?

 

Not sure on the goat, but any C5 should work. It's been a while since I bought them but you might need to buy the rear O2 sensors. Either way they'll have them behind the counter at an autoparts store. The front and rear are the same type of sensor, but on the vette I think they're really long.

 

^^ True, If you need new o2's and also need o2 extensions (for longtube headers) the best way to go is what he just said.
Go to any autoparts store and get a set of 2000 corvette rear o2 sensors. They will reach with no problem.
Also, Get some with a LIFETIME WARRANTY (free replacement) B/c they will go out again over time!

Good Luck!
