i had to scan my truck to reset a couple codes and did a "live run test" however im having trouble understanding if these values are in the correct range, ext. any help would be appreciated >also showing a inconsistant tp% (15-20ish @ idle) tb is super clean so what would cause this & how can i resolve it? also pretty sure its telling me my o2s are toast but i figured as much

 

Things look pretty good actually... Of course, Can't see 'live' data in a pic. O2 sensors should bounce around .5 volts, fairly quickly. If they stay constant, they are toast.

Short term fuel trim is adding fuel. (1.6) Long term fuel trim is subtracting fuel. The short term number will likely change fairly regularly as well. LTFT will be a bit more stable.

TPS will likely never hit 0..... but, it should return to the same value at closed throttle. If it doesn't, the throttle either isn't closing all the way, and you need to find out why, or, the sensor simply needs to be replaced.

 

Other than the TPS bouncing, are you having some kind of problems?

 

thanks that helps! the live scan has a option for it to read for about 5 min while your driving & then will show above data (the scanner is a autel autolink al519) tps had me curious after i scanned my ol cadillac & it stayed @ 0% while idling. >Nothing going wrong now, i had a ground issue that messed up my computer relays on firewall. figured itd be a good idea to take a look at things while i was checkin her out. wasnt sure about my tranny shift points also, new tranny but she likes to dig into the rpms to shift (or you have to let off it a bit to engage at lower rpms sometimes (not a big deal just occasionally annoying).. only problems now are what i now think is my power steering pump (thought it was my a/c because it doesnt work & power steering is fine) but belt is squealing like a stuck hog & sounds closer to ps pump now smh

 

The shifting issue could be your TV cable from the trans.

 

iv had to have them adjusted a couple times sine trans. (actually thats one of the ways i found out my plenum was blown) change but luckily i worked with a good shop & sprung for the new factory replacement in place of a rebuild so its still under warranty for a lil while longer so their always more than happy to check/adjust things if needed (trans service was about 2 yrs ago) anyhow i stopped in about a month ago to have it checked out and i think its because i left her set about 9mo or so (the car fits the kids & the harley is meant 4 summer ;-) ). im trying to figure out that damned ps pump ASAP (hopefully without having to spring for a new one right now) going to pull the belt & check pulley, bracket, ext. but i dont understand why its screaming like it is.. pump has fluid, no leaks & is working 100% fine. is this something i could spray down with some lube possibly or change pulley on? just curious what my options are short of new pump because funds are tight & Cadillac needs a ridiculous part now smh if it aint one thang its the next

 

If its just belt squeal, take a close look at the tensioner. They can seize up, and not maintain proper tension on the belt.

 

well i checked everything out today & tensioner is all good, belt is great (replaced about a month ago).. played with things trying to find cause, even sprayed a bit of lithium grease on the back of pulley but didnt help a bit.. the only thing that will make it stop (for a few minutes) is the ol bar of soap trick on the underside of belt, then comes back after accelerating for a min or so

 

Then you either have a belt that isn't tight enough, or a pulley that is binding. Take the belt off, and spin everything by hand. See what ya think.

 

gave everything a look over again & pulled belt, the only thing that made any noise was waster pump (a light, consistent "whirl").. this has really got me confused, squeal almost sounds like the water pump area however water pump is new & operating fine. im wondering if my truck might be temperamental about the brand/kind of belt mabe ..? even if it was water pump why would soap on the belt quiet everything for about 15-30 min of runnin the ***** off of her before she starts to squeak again? lol
