Installed rebuilt 703 injectors in the jeep "1987" yesterday and now it dies when coming to a stop, Any ideas? It never had any problems with the old ones. And yes the wires are connected to the right ones. I'm guessing bad injectors, just wanted to check before i take them out and send them back

Get 746s.

Or, you busted the vacuum line from the throttle body to MAP sensor.

Must be PERFECT. Spray some carb cleaner around it at idle and see what happens.

Just did a set on Programbo's suggestion and a bunch of Yeehaas from Flintstone. They work better than any others I've used.

I cracked/ broke vacume lines on the 89' I had some basic aquarium hose and slide it on the vacume line and it was a PERFECT fit, couldn't help but added some silicone addhesive. Had it overlapping the oem hose about a 1" on each side then push the two oem hose ends togther done.Did the spray test and not a single leak. Just two pennies in the bucket

You'll probably be just fine.

Programbo, here on CF, sells the refurbished injectors for those of you that are interested.....

I'm not really selling them they are there to stay for now. You should get the 743's Cruiser54 said they work better than 703 there is a link for them on here.
