ecmlink dtc's, start issues

[99 gst spyder]

I was on my laptop messing around with ecmlink.

Went to the dtc's section and one code was there, it was something like a coolant temp sensor, but I hit the erase all and it did, but how can I check if there any more code? Does it just pop up in the dtc box?

Car start's everytime but then dies after revs. There's four bolts to hold the throttle body to manifold and i'm missing two of the bolts. Intake pipe has two hole for vacuum, one is pluged and one is open not.

I should be getting fuel, spark and compression that's why it's starts but why is it dieing on me.

Thanks

Yes, after your car turns on, within minutes, a code will pop up in the dtc box if it detects an issue. If its intermittent, than it will not always show up right away.

Now for the starting then dieing, its probably because of a huge boost leak. Do a boost leak test, and fix the leaks, then see if it still dies on you.

Ryan pretty much hit the nail on the head..

Coolant temperature directly relates to fueling. When broken, the CTS will show (typically) a negative or erratic number. The ecm is seeing such a low value for coolant temperature that it is compensating by dumping fuel.

I found the problem yesterday. There was massive leak, I guess from the throttle body which only has two bolts holding against the intake manifold. I fixed that and it started up, I'm so happy it wasn't anything serious.

Thanks.
