Re: -.1
The old MAF's mixture was good at about 0.75%. I swapped it out because I had rough idle. However, that was also with 2 leaking fuel injector O rings and with the old fuel regulator and accumulator (so I don't know if the old MAF is the culprit for the rough idle).
I can't get the new MAF to go down below 2.95% at idle but I checked again today and the CO does go down when I revv - goes up when idling...so at least that's a relief, don't know what happen the other day.
The CO was checked with one of those professional machines, at my mechanic's workshop. Inconvenient though... else, I'll swap out the MAF back and forth !
I found 3 vacuum leaks - including one major (brake servo vacuum connection), 2 at the fuel regulator and accumulator (basically the Y connector had hardened). Fixed them but no difference to the CO. At least my brakes now feel like they're assisted.
Now, should I rip off the cover of the MAF and fiddle round with the spring ? I presume I should tighten the spring ? For leaner ? Is this an easy to do ? And obvious ?
The funny thing is that the car now idles and runs sweetly, I'm just afraid that my plugs will eventually foul up.
