Cuz I read tons here saying they have black smoke due to running rich at WOT, and they are spose to do this....to avoid a lean condition at WOT
I had my wife follow me for a few minutes while we were out today, and was verifying this while she watched from behind while specifically looking for it, and at no speed, or even when I nailed the accelerator, I gt no smmoke at all...
Is this a problem, I know the question may sound silly, but IF I am running lean at WOT, what might my mixture look like while not in the "closed loop" or normal throttle positions???
I was running a little warm, guage reding between O and R after being in city(or town ) traffic, but I was under the imnpression that this has nothing to do with the "closed loop" WOT condition.
It is my understanding that the engine will run a little rich by default if certain cold conditions are met , but only in the normal "open loop" condition.
Either way, it sure wasn't cold....
Spark plugs are only a few months old....(used autolight stock replacements and a gap found to be popular at the tme for those plugs)
wires are only a couple years old....
air silencer has been removed....
SC tubes and intercooler were cleaned when I did motor mounts a few months ago, but funny thing was, there wasn't much "goo" in the induction system at all. Thats why I beleive it has been rebuilt, or at least HGs done at some point...
I usually get about 350+ miles off a tank, but have gotten 375+ if I stay outta the gas.
It seems to have gotten better mileage since I have driven it more after it has sat for over a year... I was getting about 250 BUT it was realyl cold then. So I am curious if the better mileag is a function of getten "re-broken-in" or a function of the warmer weather....
I also "feel" like my exhaust is restrictive... I can't really explain why, I guess it feels like there is a little loss of power. or a little "flat spot" in the power between 2-3rd gear at low normal driving speeds.
My cast do not "glow" as I understand they will if getting clogged...
I Ported the exhaust manifolds, while changing out my motor mounts. I USED TO have a perfect SC, and I don't remmeber thenpower feeling this way.
The mileage on this SC is a big mistery, as it has had a broken odometer, which was replaced at "75K" miles but no idea how long it was broken....
I feel like I have been blessed with reliability, in comparison with a lot of problems I hear about here. I beleive the engine may have been rebuilt, and also the tranny... It shifts like it is new, and even if the 75K was accurate (doubtful) the 75K+my 8K would be a long lasting tranny...to shift this good anyway...
Just trying to keep her healthy... and keep things properly tuned!
OK book over, just thgouht I would throw the details out there. Thanks for reading.
Input is well appreciated
