Hi everyone,

I am currently having a maddening issue with my 1998 420 Si, 16 valve T series 2.0 liter.

When I start it it's all fine but after driving for roughly 4-5 minutes, when it properly warms up, the ignition starts cutting for a millisecond. The idling is completely fine but it does this whenever I rev it. There is no specific RPM range for it to do it, it does this whenever I push the throttle.

My current suspicion is the crankshaft sensor as the coil was changed and the IAC was also changed and the problem pursues.

I would greatly appreciate all the feedback.

Thank you kindly.
