Impala came in shop with a P0372 and a P0133. Performance complaint was will go dead on take off after warm, always starts back, sometimes a long crank.
We replaced the Optispark Distributor with hall, ignition module and coil.
Now has P0336 and performance issue of will stall when putting in gear when hot. The Lo Resolution Angle shows +17 to +21. The value should be -10 degrees to +7 degrees.
Replaced the Distributor with a different brand, same issue. Replaced with an Accel, same issue and same incorrect angle. Replaced the timing chain and gears and crank sensor and pigtail with same results of +17 to +21, P0336 and idle stall when warm when putting in gear. AC Delco or GM Distributor.
