89 YJ Fuel Injection Conversion

[Jeepsburg]

I have an 89 YJ. I think I am having a bunch of problems with my old carb (bad idle, will stall sometimes after starting or when not warm yet). So I really wanted to do a Fuel Injection swap. I had a few questions though.

1. What is a good model to use
2. Where can I get it
3. How much does it cost
4. How hard is it to put in
5. Would I have to buy any other accessories, or should it work puuurfecto

Thanks so much to any one that answers, Jon

You can get near FI performance from swapping to a Motorcraft 2150 carb. It requires a Mr. Gasket carb adapter.

The stock Carter carb is known for running like crap as they get old. Rebuilds are futile.

It's FIXED!!
I know it has taken a long time to get here, but I finally finished my Fuel Injection conversion swap.
I still have a few questions thought if someone knows the answer;

1. The instruction mentioned something about the manifold heater needing to be connected (the swap un-connects it), but I was not sure if I should hook it up, and how to go about doing so, if you think it should be done.

2. I am running my ECM off of the 12V switched wire that used to run to my old ECM. Do I need to switch it to a new line or should that work fine.

3. I have two secondary air lines that connect to the catalytic converter, that used to be hooked up to the old carb air cleaner. Can I just let them hang there or do I have to do anything about them.

Thanks so much for anyone who has given me input and though in this process.
If anyone has any questions about the conversion swap, I will be glad to give some input.
It cost $1200 from 4wd.com, but they were very nice and price-matched it down some with another web site.
