Question

Misfiring - Please help

Hi, I own an automatic 2000 Ws6 TA: LS1 with 92mm throttle body and intake, headers, cam, trickflow head, forged pistons, forged connecting rods, crankshaft has been cut with updated bearings. New Transmission, New engine. Remote start

The car has been tuned and is misfiring. We have already: changed the spark plugs, wires, coils. Checked the valve springs to see if they were broken. Nothing ...

it seems to misfire between 2,000 and 2,500 rpms.

Does anyone have any ideas?

Please help

Check to make sure none of the plug wires are touching any part of the metal exhaust manifold piping....at all.

That has caused mid range missing allot of times.

Thanks - I will definitely have that checked as soon as I can. This is giving me a headache. I am hoping there isn't a problem with the intake ... can't afford to replace it and its only a year old.

A broken spark plug can cause it too....if the ceramic cracks.
