Afraid to drive at night?

 

I'm actually wasting valuable time on here when I should be studying.

 

FUELSYS-B shows CL the whole scan.

 

who knows? I havent even viewed the log

 

Are you still getting that flashing battery light? That was a problem that a few of us had when we swapped in 02 PCM's...I cured mine with a newer alternator and running a second wire from the alt to the PCM (can't remember what pin). I'm sure that there's a way to tune it out though, if you haven't figured it out already...

 

Yep, I set B1638 to not report......

 

yea, you can just disable the light. samething happened to mine.
P1638

 

Man, this sounds rough, makes me not want to start my own tuning.

 

It's really not that big a deal...my biggest problem is I dont have a wideband. Having that solves a lot of things because I could easily then do the auto VE and get that tuned in. I could also see my actual AFR.

And once I get some free time and money in July I'm going to look into some new intake manifold gaskets.

I'm also beginning to wonder if I have the smaller 99 injectors in my truck? My truck is an early 2000 model. I asked a member here a while back and he said all the 2000 auto trucks got the 24.7 injectors, only the 2000 manual trucks got the smaller ones.

 

I was under the impression that only the 99's had the smaller injectors...I guess that your original 4.8 tune is long gone? You could check injector flow rate in there....
