I've got some weird problems going on with my LT1.

Recently I switched over to the delteq ignition system. The led is always on like it should be.

It ran really bad the first few times I started it. Then after like 5 starts, it ran perfect, like before. Drove it around all day, it made tons of power.

Then later on in the day after the motor cools off, it runs like crap again. Very rough idle, motor shaking. So I try resetting the pcm by pulling the neg battery cable for a few minutes. It then runs perfect again!

We'll, i hooked up datamaster today to see what the motor is doing at idle. It is in cell 16 like it is supposed too. The right and left integrators are 128. But the right and left block learns are both stuck at 160, even at closed loop.

No trouble codes yet.

Any thoughts on what I should do next?
