This is also the Same Zed that had a 'Too rich on Throttle Blip' just off Idle.. It would stumble badly if you let it get below 1K RPM when starting out from a lite. Early on in the Troubleshooting, the TPS/MAF/Injectors have been swapped between good Cars.. I've had to flatten out the ' Enrichment Graph' to where it's now flat like some TT Tunes.. And that fixed the Off idle Stumble.. Fuel Pressure is 'Normal'.. No injector leakage suspected.. and it will Idle in Closed loop watching the O2 Sensors Readings ( narrow Bands ).. Fuel Trims are running around 100.. with one bank ~106 and one bank ~98.. This car is put together from 3 zed parts.. it's plated as a '90 built in Late '89, running a 8 But Auto ECU chipped with a Manual E-Rom in a Moates Conversion..The Car is a Manual, and the Chasis was Org a Manual with all the Proper Wiring.. Thanks Sam..
