i had a guy on long island where i live tune it, tr6 plugs and the gap is like .30 i think?

stock fuel pump, and fuel filter was changed about 15k miles ago, when he read the numbers he did say i was "close to being maxed out" on my fuel pump. now im not sure what that means, i know a bunch of people running a 3.4 setup on a stock fuel pump

2 things...

1) Your tuner sucks wang if he is maxing your your factory pump on a 3.4"...your motor is probably flooded and your running richer than sin.

2) Plug gap = .050" - .055", not anything like .030".

The reason the car runs better cold is your knock sensors don't become active until about 160F. Therefore you have no protection against knock. Which is why it's bad to beat a cold car.

If the plugs, coils and wires are good, swap the ICM. It's odd, but I have come across ICM's that weren't firing one cylinder.
