Hmmmmm..... I have now either replaced or swapped the following parts:
Coil, Plugs & wires, cap, rotor, fuel pumps, OVP relay, fuel pump relay, EHA unit, fuel regulator (on the side of the throttle body), fuel distributor, airflow sensor, TPS (the switch mounted on the lower "flap"), CIS sensor in intake, EZL unit and Green lead. I think tomorrow I will try the distributor... I wonder if my wife would miss the kitchen sink?????
Same symptoms: stumbles on heavy acceleration from a stop (like a stop sign) them runs fine, idles fine and accelerates fine if done slowly or after moving......
