Stumble when t-stat opens...
I'm getting a stumble that sorta feels like a fuel mixture problem, ONLY when the thermostat starts to open. Car runs great when cold, or when warmed up. I'm assuming no codes are being thrown because the SYS light isn't on (thanks, Case, for explanation in another thread!) and I thought I'd ask here before crawling under the steering wheel to get at the OBD connector etc etc.
I'm driving a 94 LT1 6spd bone stock. Anybody out there that's already solved this one?
Thanks!

I am having the exact same problem with mine. Same car, only mine's a black coupe. There's alot to check like : a possible vacume leak, bad opti, cap and or wires, faulty TPS, bad coil, etc. Needless to say, I'd be more than interested if you narrow down the problem first. I'll post if I do.
