J30 just died on me after putting in a new radiator??

[95j30okc]

OK so my radiator had been losing fluid, so I just put a new one on it, flushed the system a couple times, then go drive around a little bit.

Car drives fine for about 10 minutes, then it just dies. I try and start it, and it keeps turning over, but never catches. I wait like 15 minutes, try again, and it starts right up. Somehow I make it back to the house and park it and just let it idle, and it dies in about 2 minutes.

I started it back up, and for some reason it was idling at 1700! (usually 700-800) The RPM's started dropping slowly until it leveled out where it typically idles, stayed there for about 30 seconds, then started dropping and it died, yet again.

I havent done tons of work on this car, and i have no friggin clue what going on. Thanks for your help!

Does the car overheat?

Did you re-use the old thermostat?

I have a feeling your problem is unrelated to the new rad. Have you pulled codes?

Nah, it wasn't overheating, was leaking a little.

I just pulled the codes this evening, and sure enough, they are the commons ones:

13 ECT Sensor
32 EGR Function
34 Knock Sensor

thank God those are the ones that always come up

That ECT code could be your problem.
Connector tight on the sensor ??
