ROUGH IDLE AND ABS CODES BUT NO WARNING IDICATOR.

2004 BMW 330ci • 6 cylinder 2WD Automatic • 67,800 miles

2004 Bmw 330ci

Okay so I changed the spark plugs in my car, looked at the ignition coils the seemed fine, did an obd ii scanner check on my car and it show's the #3 cylinder running in the negatives -3. Where as all the rest of the cylinders are running close to positive or higher. Is this a fuel injector problem. Or can it be the adjuster on the intake manifold or the t-shape idle regulator valve. The car seems to have a rough idle.
But shows no codes for engine problems.

Second of all the obd ii scanner is mentioning these problems
Abs 5e24 pressure sensor

Wouldn't the car have set abs warning light on, full time

The problems you are experiencing could be from issues such as a bad coil or an intake manifold leak. The information provided is generic in nature and therefore I am unable to pinpoint cause at this time. The ABS issue could be simply a plausibility fault, clear the fault and see if it reoccurs.
