Hello everyone!! This is my first time using this program. Ive used some others with OBDII software.
I have a 94 suburban 350 TBI and when I connect to it while the key is on vehicle not running it connects fine. I can see all my sensor data while monitoring. But when I start the vehicle all the sensor values jump wildly and the program tells me it is getting errors. Shutting the engine off and leaving the key on and all returns to normal. I've done some searching and have not come up with anything so hopefully someone can help.
I've tried messing with settings and changing around com ports I case it's a computer problem but nothing seems to affect it. I bought this cable from 1320 electronics on eBay.

Wow, thanks for replying!! I guess I wasn't subscribed to my own thread. I've tried a few different ones. All from this site listed for 94-95 truck and this ECM 16197427. On a side note I took the truck to my brothers house to use his snap on scanner and it wouldn't communicate with the truck either.
This is the first one I tried http://www.tunerpro.net/download/bindef ... 4_v200.xdf
