Lt1 24x swap issues
I have a 97 lt1 with a torqhead 24x (0411) pcm conversion.
My main problem currently is bank one STFT have been way off the chart. Adding 14 to 20% and sometimes up to 40 percent. This never hours away under any throttle.
Bank two seems almost normal usually minus 10 percent or better. Goes to norm under throttle.
I activate my LTFT but have not been able to get them read.
U can smell gas in the intake as well as in the oil. I did happen to have smoke come from my intake when I pulled the throttle body.
My vac seems to be low also. I have a 355 with a 234/244 cam on 110 lsa about 6 to 8 inHg at idle.
Now I have no reason to believe I have vac leak.
I've read quite a few posts where they've had the same issue with one bank over the other but it was an injector wiring or firing order issue. From what I know torqhead has that controlled by internal changes in the pcm.
I swapped throttle bodies today and then went back to the original and now I get a crank sensor code p0336 for no reason.
Car starts but runs rough wants to die at idle. Does die most the time.
I can get it to idle at times but feels different.
Also looking to see if anyone will look at my tune.
I'm sure i have more..
Thanks
Bobby
