I haven't, maybe I'll get a opportunity to do that it's weekend and report back

there is tech 1 data for the lt1 at the top of the section. it is limited to 93 so maf is not there. there is tech 1 data for the 3.4 in the v6 section.

I was just wondering about EGR, not MAF. SES light has not come back on since replacing the EGR valve last night. Might have fixed it. (hopefully) Still has a slight stumble at low speed cruising, like 35 mph in 5th gear, just cruising along, light pedal pressure, I can feel it miss. I wonder why it does not trigger a misfire code, or does OBDI not have misfire codes? If I press on the gas more and it goes away.

The Actron CP9185 will read just about any code, from any vehicle that has a computer. I have the CP9185 and just about every adapter cable that is made for it. I have connected to very OBDI car that I have ever tried, and it works like a dream come true on my 1994 Camaro Z28 (auto) and my 1994 S-10 pickup (4.3L, auto).

I have also used it to get codes from my 2008 Silverado, 2000 Jeep Cherokee, and a 1998 Hyundai Accent (all OBDII). I could probably hook it up to the space shuttle and pull the codes if NASA ever wanted to put one back on the launch pad.

sounds like its lugging. should not get the rpms to low in a high gear. getting off topic a tad, maybe start a thread.

I believe I have the older model of this scanner, the 9045? just had to purchase the cable for the 94 seperately (I think it's the 9185 cable). I think I got it for around $100 on ebay, and another 25 for the cable. Not exact prices but it's pretty close.

Agreed.

I use the Innova 3140. It's good for OBDI and 2.

35 in 5th gear? Is it a 6 cylander? Regardless, that's simply to slow to be in 5th gear. You may well indeed have a stumbling problem. But if it goes away once you bring up the Rpms, you know ur just lugging it at to low an rpm. Get into fourth and stay above 1500 Rpms. Not good for the trans to buck like that. if it still shows the same symptoms at a higher rpm, start digging.

Yeah, I meant more like 45 in 5th. I'm also running rich as indicated by my tailpipes turning black wihtin a week of shining them up. I wish it would throw a code so I could figure out wth is wrong with it...lol. OBDI is just about useless.
