Mods are in sig. The car has always had a little surge with the TR230 cam, but it has started surging really bad and dies fairly often, especially in the first few minutes after startup.... hot or cold.

I've done a PCM reset and an idle relearn (tried more than once) and it hasn't changed even after driving a few hundred miles

Any ideas? Plugs maybe? I have about 10k on some TR6's.

Any tuning done to it?/

I'll check over the hoses tomorrow.

MTI did the tuning.

10k is alot of miles on TR6's. I'd just switch those out anyway for performance issues. I believe most change them every 3-5k.

But check the hoses that go form the valve covers to the intake and etc. Might be a leak. Also just check and make sure the intake bolts are all tq'ed down good.

if not, maybe the hooter weather has played some effects on the car. I mean did the car just start to get worse in the warmer air?

might need higher idle, tb drilled a little more, or some timing added in park. That cam can be a PITA in some cars from what I see, but mostly A4's

good luck and wish i coulda helped more

Hey Scotty sell that thing and buy a Cobra like everybody else is doing. Just kidding, call if you need any help. Jason

I had a set of Autolite plugs that were a step colder for my nitrous setup and I went 40K and several bottles of the juice before I changed them and they didn't show anything major and wore only alittle.

10-4 on the hooter weather :p

Definetly sounds like a vacuum problem. Measure engine vacuum at idle, you need at the very least 17 Hg.
