Ok, I have an s4 na fc and the oil lines leaked, so i had someone make me some steel braided line because it was cheaper than anything else. while i was waiting for the lines to be made, i thought is was a good idea to take out the oil injecters to run primix. I swear i did it right, but before my car ran fine, but now it has bad cold starts. It starts right up when warm and thats how it used to be for cold starts. i've tried everything, but i did take out what i thought was the cruse control, but was it the "choke" for the lack of a better word right now. it had a vacc line and a throttle line and a plug going into it and it was right next to the charcoal canister. Was this a bad idea? Also, it burns oil because the oil control rings are going out, but it never was a problem before. thanks before hand. Sorry, i'm on vaccation so i can't take pics, but will when i get back.

no choke means you're gonna have to do manual idle until it warms up; unless it's not starting at all, in which I'd look into the unflooding procedure.

Unless you swapped EFI for a carb, you don't have a choke. Yes, cruise control is where you described, sounds like that's what you removed. Dunno about your problem, though.

How did you plug the oil injector holes?

And I know it doesn't hace a choke, but the mechanism that is equivalent to that on this engine. I believe it uses thermo wax. Is there any sensors that I may have left unpluged when i put the uim back on?

A bolt I'm assuming you used to plug the hole? It's an odd thread type and the shop that built mine used hex screws I believe with locktight or something of that nature

Yeah, but it really doesn't sound like a vac leak because it runs like it did before when warm. I've done a lot more resurch and everthing and I need to look at my car again, but i'm still on vacation. Sunday I will post pics of everthing so you guys can hopfully tell me what I overlooked. Thanks again guys.

Wow, so I got tired of not having a car so I decided to do something about it. I cleaned the plugs and added a ground, but no luck. I thought I'd check for more vacc leaks when I came across something. My damn temp sensor was unplugged! I swear I checked that, but i'm glad I didn't spend money on crap. Thanks for the input guys

Did you put the injectors in backwards cause if you look at the holes on them one is smaller than the other
