Ok i cleaned my bac valve and i have a good idle with no loads on the engine, in the morning i crank the car and it dosent rev to 3000k or so, and im guessing the cold start thing isnt there, and now when the car is warmed up and i cut it off it cranks just really slowly, like it cranks and stays at like 500 rpms until u gas it, what could this be, and also, on the s5 gxls thats what i have, they have the alarm system, and usally when u press the lock down on the door u hear a beep and the little light comes on, it didnt do that this morning either, whats the prob, all this started at the same time, when i cleaned the back, could this be a fuse or something or what.

Help me before it gets out of hand

 

anyone

 

any ideas

 

bump

 

compression check?

 

How did you clean the BAC? No harsh solvents, I hope...

My S4 will do that, every now & then, on a hot day (start her within 30 minutes of shutdown, she'll idle low & a little rough for a while, but goes back to normal when the throttle is "blipped")

 

i just used thinner, the same as carb cleaner i think
