I built some ram air scoops and ever sense I built them my car doesn't want to idle when it is warmed up. When the car is cold it is runs/idles fine. Once its warmed up it wants to idle around 2,000 and when i go to brake, the idle is lowered below 2,000 and the car runs like **** and throws code 33(low vacuum) Could the scoops be effecting the idle? Any suggestions will be greatly appreciated.

 

uhhh... not unless you are trying to idle at 140 MPH... and even then...

sounds like you have a huge vaccume leak or bad senser somwhere. unplug your MAF and see if it makes a difference.

 

correct me if im wrong...but I think his 91 has a MAP, not a MAF. Just had a problem with a code 33, but I could have it backwards.

 

91+ is speed density,they have map sensors instead of maf,make sure the vacum line is hooked to the map,and isnt broken anywere,if thats all good,get urself oen can of carbcleaner,and spray around all the vacum lines,and places were there would be gaskets on the intake manifold,if the idle jumps up even higher or the car stalls when u do that u have found ur vacum leak.if nothing changes u prolly just have a dead map sensor,
