I've recently swapped my hatch to b series but I have a problem. I can get in the car and turn the key, it will fire up. It's a rough idle not like insane but it's rough. I had a obd1 dizzy on it when with a converter I first got the ls in and was ready for fire it ran. It was idling up and down thou it drove fine with out bogging. Then I took the top vacum hose on the front of the intake manifold and it stopped idling like that and it ran decent and drove without bogging. So then I went to put new spark plugs in it 20 minutes later and I started it everything was smooth until while it was running my buddy popped off the spark plug wire from the spark plug, instead of bogging down a little it shut off. It turned out I blew the dizzy. My buddy worked magic at advance and got me a free dizzy, only problem it's obd2 big plug. After i got the dizzy i put it on. Everything went smooth it plugged right up and fired. Itt was idling fine. Left it for about 25 min. Then tried to drive it. When i went to give it gas it bogged down and tried to die. I advanced the dizzy and adjusted the tps. I dont have a icv thou. Could that be my problem???? I need help someone please input on this and let me know if you have any ideas please.

Trouble codes? I haven't been able to run a obd gun on it,haven't made it thAt far down the road :/ I will try and get one tomorrow

Most likely going to need to hook up a computer to it,I'd advise that over throwing useless parts into it it's obviously an idle problem however it could be an ecu issue with the fuel

Yea I was thinking ecu too maybe.im not sure what ecu I'm running. Do you hAve an I dea of what one I should run?

You should run the ECU that came with that engine, like a P74 or P75 or whatever. Then pull the trouble codes, because a lot of the answers will become obvious after that. And you do need to use a IACV.

I'm not sure how you're expecting things to work properly if you're ignoring fairly obvious things...

Oh I know I need an iacv but the wiring harness that was in the hatch was cut by the previous owner. It doesn't have a plug for the icv. I'm not sure which two wires it is so I can wire a plug to it. I know it seems from what I wrote I'm cluelessly slow at cars but no I know a bit just am stumped at this point. I've tried looking for a diagram so I can wire the icv but I can't find anything

What's does a firebreathing business man have to do with this?

Hahaha.

It has absolutely nothing to do with it.
