Distributors and Trigger Points (New Dizzy Installed), Troubleshooting Parts - CHT appears bad Options

[tvdinnerbythepool]

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?

I have the same issue with my 71-4.
Checked everything on the D-Jet and still random stalling (or almost stalling)when hot.
I will swap the ecu (have a NOS) and see if there is a difference. I suspect that maybe there is a bad soldering somewhere on the print. Had this on a BMW E30 years ago. Drove me nuts until I opened up the brain and found a capacitor came loose. Maybe a search option?
