My 02 TL just started surging while warming up, almost sounds like it’s going to stall. If I drive before it gets hot, my acceleration will give be jumpy problems and short blips of lost power. If I put it start flipping through R, N, D in idle my lights start to surge and dim?

all of this goes away when warm.

I’ve got no codes. I’ve changed the spark plugs, replaced the ECT sensor and cleaned the EGR ports.

Any insight would be great!
