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!

Hey Guys, Thanks for the response.
Long story short, I ended up with 2 Distributors - Bluetooth and a Non Bluetooth. I have opted to use the non bluetooth version. Setting A with Vacuum advance. I could not for the life of me get the thing to run with the bluetooth version with proper curves programmed. Here is where I am at. I replaced the dizzy due to obvious wear and running issues but it did NOT solve my issues... -Wildly varying A/F readings -Inconsistent idle -New issue noted during all my misery today....quite a bit of white smoke coming through the oil filler tube with the cap off. I was surprised by how much. I think the motor may just be too damn worn out and need a rebuild. I plan on doing compression test tomorrow, but I think all the smoke coming out of the oil filler cap is already my answer. I'm also not convinced I don't have an ECU issue that is causing such big swings in A/F ratios. I'm tired and annoyed and another $600 deep with a shit running car....signing off for the night.
