Since last year my X has been running rough on start up, both cold start as well as hot restart. It sounds like it's on 3 cylinders, but there is no single cylinder out. After 5 minutes of this, it seamlessly smooths out and runs fine.
If I disconnect the spark plug leads to cylinders 1, 2 or 3, I hear no change in running, but if I disconnect #4, the engine dies pretty much right away. I have spark in all plugs, and plugs are clean. I hooked up a fuel pressure gauge, and it seems my fuel pressure doesn't go above 40, is that low? Injectors were cleaned professionally about 17 years ago, or 15K miles. I can't think of any other condition that would resolve itself in about 5 minutes.
Ironically my Nissan has a sticky lifter which also takes about 5 minutes to quieten down...
