I have a miss, and am wondering how much slower my car isnow. I have a manifold leak at the gasket. A leak at the egr.one of my pass side 02 wires came loose, but is now fixed. I have stock 02s w/ lt headers, and I think theyre bad. I have the home made 02 extensions, and also when i took the plugs out during header install, i dropped a couple, and at the time, didnt know about gapping the plugs, so I just opend them up. A couple of them are too tight, and a couple to open. Im geeting all these problems fixed, plus a neww opti, 02 extensions with the harness connectors, coil, and wires. Anybody know how much I could currently be losing w/ these problems? thanks

 

It's anyone's wild guess. There is no real way to tell.

 

Ohhhhh Swammee,---
Ooooops my crystal ball went dark.

 

I have a terrible miss with my setup and ran a 12.64 for now... hoping a low 12/ high 11 second run.

 

400rwhp...I ran 12.00 with 300 rwhp
