N52 dying on cold start
Z4 with an N52. Idle would fluctuate on cold start and at the bottom of the rev it would die. Starting right after or when warm does not have this behavior. This used to happen without it dying but now it does. Smoke tested the manifold and valve cover, didn’t see anything. Smoke tester would pop off the throttle body because of the pressure. Valve cover holds vacuum.
Things I installed: MILVs Three stage intake manifold Carb legal headers Oil cooler adapter Things I replaced: Valve Cover Spark Plugs Coils Valve cover/manifold hoses Water Pump Alternator Belt Belt tensioner Starter Upstream/downstream O2 sensors VANOS solenoids Video: Last edited by gaseosx; 11-09-2024 at 03:11 PM.. |
