Subtle change - and I love it!
Also - due to the low control pressure when the car was in I put the 090 WUR I had in the vehicle (had an 033 when I purchased the car).
It’s running rough - but working through some troubleshooting while I wait to have the motor pulled.
Right now with the 090 in - when I unplug the relay under the drivers seat nothing changes to the idle, which I believe means it is non functioning. To that end I am going to replace that - and crossing my fingers it really helps to straighten some things out.
If my research was correct - while running the 033 WUR, which is designed for older models - it was simply bypassing the 02 sensor, that relay, and any fuel enrichments that were supposed to take place because of those and the frequency valve.
Here’s to hoping Mav is one of those stories that the simple relay replacement really wakes up the car and straightens some things out! I am certain I still have some air leaks to work through - but bit by bit working my way through it.
Stay tuned as the sorting continues!
