I changed my radiator today and now the engine won't idle. It will run if I give it some gas, but the second I let up it dies. I reconnected the terminal at the airbox ,the low water wire and the two wires at the bottom of the radiator. I cant think of what I've forgotten.

 

The only thing i can think of is the two lil conectors at the bottom drivers side of the rad. If im not mistaken that is the temp sensor for the high idle startup, i maybe wrong. But, the thing is, my car runs fine with out it. Maybe play with it. The problem is probably not your rad at all though, check and readjust your TPS and idle screw. and check for any vac leaks you may have gotten while maybe bumping into something. Good Luck!

 

More likely to be an air lock in the cooling water supply through the BAC.

 

Six, so? The coolant running through the BAC isn't doing squat for idle.. The BAC valve runs fine without coolant.

Could you have removed any other electrical connectors (i.e. AFM) while removing the radiator that you didn't hook back up?

 

Thanks, I'll check again tomorrow. I disconnected/reconnected the terminal at the airbox, two prong one at bottom of radiator and one lead one top of radiator. I can't think of anything else I missed, but I'll double check.

 

Whoops! I went back today and looked at what I had done the day before(it was a long day!) Well, I forgot to hook up a large hose that goes to the bac and a couple other places. Car runs fine now.
