Here's the story.
I have the maftpro speed density. With the stock o2 sensor UNplugged I don't get a code 21? With it plugged it it doesn't change anything.
When I unplug it for PTT it doens't throw the heater circuit code how could this be? And with it unplugged I still get a VF voltage...
Sorry I should of told you I have 100% GTE eletronics from a 87-88.
Why I don't get a code 21 with the o2 unplugged, and why the stock o2 doen't do anything is confusing the hell outta me.
Code 31 i'm buying resistor today for the HAC.
And code 34 I dont get either, how would it...
thedave925 are you saying if you dont fix those codes tuning will be hard? I thought they wouldn't effect anything?
Anyways I don't want to thread jack but figure it'd be good to keep this together.
I'm running 87na-t maftpro spd dens. I got codes 24,31,32,34. It's like my cars AFR have a...
GO BUY A LOTTERY TICKET!!!!!
Cars doing whats it supposed to, TOO!
...but you don't need thread sealant on your turbo feed line.
also maybe I missed it, but what was the problem?
yah it seems wierd, but hmm 3 weeks later, trannys fubar:icon_roll
and whats that have to do with the motor sneakypete?
roadboy, the stories he had were of older gm vehichles, but how do they differ from import autos?
It's prolly an old wifes tale but my instructor told me if a tranny isn't regularly service, and you change the oil/filter after its hasn't been changed in years you prolly shouldn't. I'm not sure how much proof/truth there is behind that.
Supracentral, guess what I just ordered. We send out oil analyisis all the time for equipment at work, but didn't know the general public could get it done for so cheap. THANKS!!
As for my suggestion to cut open a filter, usaully by the time you hear knock there's a good chance you'll see a...
Me neither but I have a MAP sensor. Some things you can cheap out on, but when it comes to the mechanics of things Toyota did these things for a reason.
I got the maftpro aswell, I've never used the safc but the maftpro can handle everything. It's as close to a standalone as you can get. If you use the 680's you can just turn your mainscale down to adjust for it, not sure if it will affect atomization/spray pattern though, somone with more...
I didn't say spun, he'd know if it did. You'll still get a bit metal in the filter if knock is developing.
I totally missed you said it might be the valve train CajunKenny, you could pull the valve covers and check you cam caps/valve lash ect.
Notice a change(a drop more importantly) in oil pressure? Cut open your oil filter next time you change your oil, squeeze the oil out of a few pleats, and shiny=bad. Good Luck...
