I'm working on a 2000 S3T with Andrews n6 cams, forcwinder, race ecm and exhaust. It has a major engine studder under a load. It runs fine in the garage, other than a pour idle, but when it's out on the road under any acceleration it misses and has no power.

I've tested: fuel pressure, injectors, coil, swapped out ecm's, tps/afv reset. The next thing I was going to go after is the cam trigger.

Any suggestion from those that know would be appreciated.

Thanks Matt

Replace the ETS.

Don't overlook the HT coil leads & spark plugs

I'll try those things. I've got a few ets's laying around so should be a quick test.
Thanks Matt

I got it fixed.

Stupid me. I should have looked at everything the dealership did first.
They "adjusted" the timing. I went to check it and found they used the holes instead of the slots to hold the cam sensor plate on; so you couldn't adjust the timing. Dialed the timing in and runs great.

What a bunch of morons.


Thanks Matt

The Service Manager strikes again.

Don't let him install a Kooks exhaust for you...
