5 grand idle ??
Re: 5 grand idle ??
my friend actually had a problem with his car runnign at a low rpm also and also with dieing while driving sometimes, his was fuel pump, very easy to change out IF u do the hole in back thing, its actrually very easy to do it that way, saves LOTS of time and cuss words, i recommend u get a fuel pressure tester from advanced auto or auto zone and test the psi, and when u turn the car off it should hold the psi at that level when car is on or no more than 10 below it, thats my guess

Stock programming for an A4, fully warmed up, is 550rpm in gear and 650rpm in neutral. There is a cold idle table:
A4:
COOLANT TEMP - IN GEAR - IN NEUTRAL
-40 ------- 800 ---- 1200
-19 ------- 800 ---- 1200
+3 -------- 800 ---- 1200
24 -------- 800 ---- 1000
46 -------- 800 ---- 950
68 -------- 800 ---- 900
89 -------- 800 ---- 900
111 ------- 800 ---- 900
132 ------- 750 ---- 850
154 ------- 650 ---- 750
176 ------- 550 ---- 650
>176 ----- 550 ---- 650
If the idle doesn't match properly, it may be a problem with the IAC valve, or plugged passages for the idle air flow. Check the IAC valve "counts" with a scanner, and see how it reponds.
