In Windows 10 you right click on the logo and select device manager.

I hadn't gotten that far with windows 10. Tried everything I could. Couldn't get it to make a connection for some reason. Downgraded it to XP lol. And then when I couldn't find the option in v5 I did version 4 and it was right there. But I'll try it again when I get back home.

Thanks again man

Today I learned that Gateway made gaming laptops... And I've been into computers since the 386. :lol: That's a new one to me!

It looks like you have a couple stored MALF Codes - 13 - O2 sensor bad and 34 - low MAP but they seem to be working OK. You need to reset it by disconnecting the battery for a few minutes. Your Integrator (it went into closed loop at ~120*) is calling for ~128 which is good but, at idle the Block Learn Multiplier is low meaning rich. Your timing, once warmed up is jumping from as low as 16* up to 22*, don't know why. It looked like your idle was pretty good 650 - 700RPM. When you revved it up you got 74 Knock Counts but it didn't pull any timing. By just revving it up you shouldn't see any KCs. You probably need to take it for a drive and try to duplicate your problems.

Again, I'm guessing you have a 7427 PCM, it would be nice if we had that confirmed and what bin you have. I'm using A219$OETP5v250.adx to run your log (with the assumption on the '94 7427).

Anyone else wanna take a shot at it?

The stored codes are from when I unhooked them when trying to do some troubleshooting. So those are just retained from my doings. As far as knock count I'm not sure as I was testing it before with a wrench and tapping on the side to make sure it got voltage. Unless it starts at zero each time I start the truck? And yeah I'm not sure what the timing was doing. As far as the file, I'm using the one straight off of tunerpro for the 94-95 c/K (should be the only option) I'm going to do a compression test tomorrow before I do a driving log. Just to make sure the valves are good and what not. If anyone else has any ideas for the time being let me know.

It started at zero (always does), then it went up to 504 while cranking (normal), and stayed there while you were idling, then went up to 574 when you revved it up.

And yeah I'm not sure what the timing was doing.
If we had the bin and confirm the PCM we could look at it and see if there's a reason for the timing jumping. You may have a bad ICM or ESC?

Did it run OK during your data log? If not, where/what did it do? You still need to clear the codes so we know they're not coming back.

Again, if anyone wants to chime in, it's greatly appreciated.

Understood. When it was cold it idled ok. But when the idle finally came down. It had the typical miss. It's not a constant miss but itll run smooth then shake a time or two and then ok and shake again. I'd say roughly every 3 seconds or so. And it takes a little longer for it to crank than normal. That's why I was curious because when the MAP sensor is unplugged itll fire right up and it runs as smooth as a new engine. Which would make me think it's a lack of fuel, but yet the ECM is stating rich. As far as codes are concerned I will clear them but not once have I had a check engine light during this whole time. They have only illuminated when I had the o2 or the MAP unplugged.
