i just installed my skunk2 intake mainfold into a b18b. i'm having trouble . seams like it been bogging alot. the idel is horrable as well. i tried to make the best of it and adj it to make but only got about 3-400 rpm at idel. it bounces to 100 rpms ever few mins as well. i raise the fuel pressure to tried to get ride of the bogging . that helps alot but i still am not sure if i am doing this all right. do i have to advance or retard the timing gear ?

 

did you connect all the right plus to where they go? you might of gotten the TPS and MAP sensor wired wroung since there both the same plug. Check it out

 

Sounds like a vacuum leak to me. Double check all the connections and harnesses. Are you throwing any codes? Can you hear the vacuum leak?

 

i lable all the sensors but i'll double check that as well. so far no engine light. i don't think there is a vacuum leak anywhere and i will double check on that. But this is the werid part. when i drive around . i hear a small whistle noise when i gas it. been woundering about that as well.

 

what intake manifold gasket did you use? And did you remove the old gasket completly?

 

i bough one from kragens(a near by autopart store). it wasn't the paper one nor copper one. it is a silver gasket. i replace all of the O rings on the fuel injectors just to be sure. i found no difference after replacing them.

 

i notice that i have alot of back fire driving around today . i set the fuel regulator back to stock psi. and got the bogging affect again. it still back fires and burns a shit load of gas. i'm hella lost . i check over every possable leak. no luck. i have no clue. anyideas guys ?

 

well it dosen't look like i can fine the problem . thanks anyways . i'm going to uninstall this manifold . look like i'm the only one with this problem . my plugs are going bad . running rich is never fun .

 

my car backfires like crazy ever since i put my skunk2 IM on my car...i went to the dyno and leaned it out and still get backfiring...i even started getting black soot on the back of my car when i put this on!
