I had a TPS go bad and it would fall on its face like that.

 

I will check it I am trying everything!!!

 

okay I have a scanner that data logs !!!rpm is 655 maf flow is 6.39 map kpa 37 ign adv jumps around a bit from9-13-22-8 and so on 02s12 v .445-.440 is all the moves that makes and o2s21 v .815-.675-.520-.900 I hope someone understands this stuff cause I sure dont I hope I can get some help!

 

If your O2s are constantly showing that much difference in voltage something is wrong, either with the sensors or with the fueling. What are the STFT and LTFTs like? Is it setting a CEL?

 

the stft goes from 0.0up to 2.3 and #2 is from 0 to 3.9 . the ltft stays at 9.3 and #2is at 10.9

 

dont see any cel.

 

I put the truck on jack stands and put it in drive and it did fine the only thing is the gauges beep and say brake ! when I dont even have the brake on also it says trac off .is this a tuning issue ?

 

im having the same problems with my ls1 swap. it stalls right out after i put it in drive after a little bit. haven't gotten a scanner on it yet though. i also have some fluctuating oil pressure when its in gear. may be the oil sending unit. but similar problems. i'll let you know if i come up with anything.

 

I FIXED IT !!!!!@!@! the etc was still on which was retadrding the timing turned it off and wooooohhhioooooooooo!! man I am happy
