recently i when to start my 86 s4 and when i turned on the car it wold start but it whold die not just stright up die but lose rpms till it whold just die but if i give it a stedy throttel (wile in nutral) it will stop and idel right and not die any one have any ideas on what it could be? ( resently took off both mufflers due to holes in them and going to replace i was thinking maybe its because of that maybe not enough back pressure
|
if it has been sitting for a while try draining out the old gas
|
hasent been sitting gas if new
|
1)What does it do when it warms up?
2)The mufflers will not effect the idle 3)Sounds like a vaccum issue to me |

Try removing the vaccum line that runs to the pressure sensor. Its on the front of the strut tower on the passenger side. The car may still die the first time you start it but start it again, and that should bring the idle to normal if the sensor is bad. Mine used to die about 3 times before I could coax it into holding idle, and then after a minute or two the idle would go from 1500rpm down to 600rpm then back up. The pressure sensor was bad. If that doesnt work, let me know and Ill give you option B lol.

No problem man, glad I could help. It took me awhile to source the same problem, but it will run fine without it. |
