Hi, i just finished up doing some mods. PnP TB, pacesetters, slp lid, tick master, new plugs, 3 inch duals with borla xr1s. Now under a load i get a sporatic miss. Could this be the computer 'learning', or do i need a tune?

CEL's?

How long after the mods did the miss start occurring? I'm assuming you have an SES light on if you put headers on? Have you read the codes to see if it's showing anything other than o2 sensors? What rpm range does this miss occur at?

Check the plugs. You need a tune, but it shouldn't be missing that bad.

No idea what CeLs are. I can only notice the miss in 5th or 6th gear, pulling around 2-3 grand

I assume Check Engine Light...took me a little bit myself since I've always seen it as SES.

Check Engine Lights = CEL's. If its that slight, I have to say its due to the upgrades. Check your plugs.

plugs or o2 sensors

Mine does the same thing and wasnt the plugs or wires, i just changed them. Car shows no CEL.

I didn't buy the O2 extensions. I spliced them myself. I could have gotten a bad splice on one of the wires I guess. its almost as though its loading up, cause it pulls like a champ in lower gears at higher rpms.

i dont think the rear o2s could affect it could it? (to that degree)
I do have the extensions on mine if this helps at all.

My rear O2s are disconnected. The front I spliced

2-3 grand only in 5th or 6th? Or 2-3 grand in any gear? Is it just one miss and then it goes away or does it constantly miss through that rpm range?

You probably have a bad 02 splice. Do it right and get the longer 02s

The front O2s will set of an SeL even functioning correctly without cats correct? Wondering if i can check them without redoing everything.

^^^ +1... If you have never changed them before your probably due for new ones by now... Get the corvette O2s they are longer. No need for extensions.

I've seen a lot of people that splice the O2's have problems. How you splice them can alter the voltage, even a little bit will cause problems.

Only difference is extensions are $30 new O2's are $150.

^^^ ya I know that. But since he splice the O2. (If that is the problem) he will need new O2s.... if he buys the Fbody O2s he will need extensions. If he just buys the Corvette O2s he will not need the extensions. Should have been more clear about what I was tryna say

Good point
