Hey all,
I am still chasing down an intermittent RICH condition when the car is fully warmed up. 1.7L D-Jet After fully warmed up with a tuned and rebuilt MPS I can come to a stop light and idle steady at 850rpms, next stop light it's bogging down to almost 200-300 and barely running. Then next light it's idling normally again. Some days I have no issues with idle at all, others I do. I've gone through all the components and troubleshot my way through everything on the PBANDERS list of "my car is running rich". I am as confident as I can be through extensive troubleshooting and testing that my ECU, AAR, MPS, CSV, Vacuum Leaks, CHT, Injectors, Fuel Pressure etc are all good. All new wiring harnesses, plugs, plug wires, cap, rotor, coil, etc. The ONLY thing I haven't worked on is the distributor. I am reading up on the possibility of the Trigger Sensor Contacts being warn and bouncing possibly shooting off extra injection pulses...could this be the cause of the intermittent problem? It doesn't have points anymore, but a petronix I believe. What do you guys think? Is there an easy test for this or do I replace the trigger contacts or the whole dizzy? Cheers!

Got the distributor installed, I opted for the Bluetooth one for the flexibility in curves...Starting to worry I shouldn't have done that.
It doesn't come with any pre-programmed curves and I am having a hard time finding the OEM curves for my distributor....any input? My distributor was the 0 231 174 001 for a 1.7l Djet. I have a call in to the 123 rep but am hoping someone on here may have the info I need. Thanks! |

Nothing you can download from the website?
Really interested to hear how it works out. |
