ok soo ever since i did the under drive pulley swap and smog delete and removed the a/c my car feels like it wants 2 shut down in low rpm's ooh and its a auto but when it wants 2 shut down i put in N and the engine spins fine any ideas????

mjr46

when you deleted the smog did you cap off the vaccum lines at the source???

skumbee

ahhh no........but this feels like the belt slides or something.....and i dont want 2 plug them cuz i need them for smog in the future[:@]

Put a screw/bolt in the vacum line to plug it and u need it again just take out the screw/bolt. otherwise ur car will run like it has a vacum leak.

skumbee

well i douth this is a vacum leak cuz i hear a wierd noice when it wants 2 shut down

skumbee

hmm but ill try it then

mjr46

either way you need to plug off the lines..follow them back to where they plug into the intake and un plug them ...lay to side and cap of intake port where they go= easy

skumbee

ok sooo right now i was checking out my car and about that thing that needs to be plug wheres exsacly is it at????
is it that thing behind the heads??????

mjr46

if you removed all the smog..I assume you removed the thermactor air diverter valve and bypass valves that connected to smog pump above passanger side header..and to those valves were two vaccum lines that go to the TAB and Tad selonoids..both have two ports.....one for source vaccum and the other goes to the valve to activate it....from the selonoids the lines go to intake I believe..if you want you can cap of selonoid ports..whatever is easiest

huh, my car seemed to do the same thing when i did those mods, but i just messed with the timing a little and it fixed the prob
