1990 325i, fairly well maintained with no noticeable vac leaks.
New o2 sensor
New fuel pump, fpr, and filter
chipped for 91 octane by a local guy
New plugs
TPS clicks immediatly off idle
Throttle cable adjusted to zero slack
Idle at 800rpm (slightly rough)
323i flywheel (12lb I believe)
Relatively good condition cap/rotor, unknown wires
Car seems to hesitate slightly when accelerating off of idle, it sometimes stumbles for about half a second before picking up speeds. It is worse when cold, but the problem doesn't disappear when hot, and in neutral it takes almost a 50%+ throttle kick to get the engine up to 3500-4000rpm. I've sprayed around every possible source of vac leaks I could find with brake cleaner and had zero luck finding any leaks. What else can I look at that doesnt involve throwing parts at it?
