Yesterday my car just up and died on me on the freeway, its a s4 t2 with a new motor. I have been very careful with the breakin process seeing as how it has 464 miles on it. I got the car back to my house and today i thought it was the alt but it tested ok.

I got the car to start back up today it seemed just fine then it just died. Started it back up and same thing ran for a bit then died. The only think different that i noticed was that the idle dropped to 1300 from where it originally was set at 1500. I havent checked the compression yet but i dont think its the motor since it starts up ok but i will check it this after noon. What other things can I check anyone had this problem?

 

vacuum leak probably check your lines and make sure all of your connections are tight

 

That's a high idle anyways, I thought FCs idle at 800. then again don't know diddly squat. I can say good luck though.

 

I have it idling high because i took off the vac rack and bac im just waiting on my standalone in the mail should fix that. I just changed the spark plugs and it runs like normal now but when i turn it off it massivly floods. the old plugs had crap all over them looked like oil. Could it be my injectors? i been getting horrible gas milage.

 

try this: since whem u turn ur car off, it floods. pull ur fuel pump relay under the steering column, wait a few hours, plug the relay back in and start it up.

most likely you have leaky injectors like all of us!

 

yeah thats what i was thinking, i think i just stalled it in traffic the other day and the battery wasnt charged enought to turn it over even doing the relay to unflood it. Seems to be working ok now dunno haha
